Whisper

##
Overview

The Whisper model was proposed in Robust Speech Recognition via Large-Scale Weak Supervision by Alec Radford, Jong Wook Kim, Tao Xu, Greg Brockman, Christine McLeavey, Ilya Sutskever.

The abstract from the paper is the following:

We study the capabilities of speech processing systems trained simply to predict large amounts of transcripts of audio on the internet. When scaled to 680,000 hours of multilingual and multitask supervision, the resulting models generalize well to standard benchmarks and are often competitive with prior fully supervised results but in a zeroshot transfer setting without the need for any finetuning. When compared to humans, the models approach their accuracy and robustness. We are releasing models and inference code to serve as a foundation for further work on robust speech processing.

This model was contributed by Arthur Zucker. The Tensorflow version of this model was contributed by amyeroberts. The original code can be found here.

##
Quick usage

You can run Whisper in less than 4 lines of code and transcribe in less than a minute!

    # pip install transformers torch

    import torch
    from transformers import pipeline

    whisper = pipeline("automatic-speech-recognition", "openai/whisper-large-v3", torch_dtype=torch.float16, device="cuda:0")

    transcription = whisper("<audio_file.mp3>")

    print(transcription["text"])

Voila! You can swap the model with any Whisper checkpoints on the Hugging Face Hub with the same pipeline based on your needs.

Bonus: You can replace `"cuda"` with `"mps"` to make it seamlessly work on Macs.

##
Usage tips

- The model usually performs well without requiring any finetuning.

- The architecture follows a classic encoder-decoder architecture, which means that it relies on the generate() function for inference.

- One can use WhisperProcessor to prepare audio for the model, and decode the predicted ID’s back into text.

- To convert the model and the processor, we recommend using the following:

    python src/transformers/models/whisper/convert_openai_to_hf.py --checkpoint_path "" --pytorch_dump_folder_path "Arthur/whisper-3" --convert_preprocessor True

The script will automatically determine all necessary parameters from the OpenAI checkpoint. A `tiktoken` library needs to be installed to perform the conversion of the OpenAI tokenizer to the `tokenizers` version.

##
Inference

Here is a step-by-step guide to transcribing an audio sample using a pre-trained Whisper model:

    >>> from datasets import load_dataset
    >>> from transformers import WhisperProcessor, WhisperForConditionalGeneration

    >>> # Select an audio file and read it:
    >>> ds = load_dataset("hf-internal-testing/librispeech_asr_dummy", "clean", split="validation")
    >>> audio_sample = ds[0]["audio"]

    >>> # Load the Whisper model in Hugging Face format:
    >>> processor = WhisperProcessor.from_pretrained("openai/whisper-tiny.en")
    >>> model = WhisperForConditionalGeneration.from_pretrained("openai/whisper-tiny.en")

    >>> # Use the model and processor to transcribe the audio:
    >>> input_features = processor(
    ...     audio_sample["array"], sampling_rate=audio_sample["sampling_rate"], return_tensors="pt"
    ... ).input_features

    >>> # Generate token ids
    >>> predicted_ids = model.generate(input_features)

    >>> # Decode token ids to text
    >>> transcription = processor.batch_decode(predicted_ids, skip_special_tokens=True)

    >>> transcription[0]
    ' Mr. Quilter is the apostle of the middle classes, and we are glad to welcome his gospel.'

Whisper is compatible with the following optimisations for both short and long-form generation:

- PyTorch Scaled Dot Product Attention (SDPA): flash attention and memory-efficient attention kernels. Enabled by default for `torch>=2.1.1`.
- Flash Attention 2: improved implementation of flash attention through better parallelism and work partitioning.
- torch.compile: JIT-compile the forward pass to dispatch to efficient fused kernels.

As an example, the following codesnippet enables SDPA and `torch.compile` for up to 5x faster inference:

    >>> from datasets import load_dataset
    >>> from transformers import WhisperProcessor, WhisperForConditionalGeneration

    >>> # Select an audio file and read it:
    >>> ds = load_dataset("hf-internal-testing/librispeech_asr_dummy", "clean", split="validation")
    >>> audio_sample = ds[0]["audio"]

    >>> # Load the Whisper model with SDPA attention
    >>> processor = WhisperProcessor.from_pretrained("openai/whisper-tiny.en")
    >>> model = WhisperForConditionalGeneration.from_pretrained("openai/whisper-tiny.en", attn_implementation="sdpa")

    >>> # Enable static cache and compile the forward pass
    >>> model.generation_config.cache_implementation = "static"
    >>> model.forward = torch.compile(model.forward, mode="reduce-overhead", fullgraph=True)

    >>> # Use the model and processor to transcribe the audio:
    >>> input_features = processor(
    ...     audio_sample["array"], sampling_rate=audio_sample["sampling_rate"], return_tensors="pt"
    ... ).input_features

    >>> # Compile the forward pass
    >>> for _ in range(2):
    >>>     model.generate(input_features)

    >>> # Generate token ids using compiled graph (fast!)
    >>> predicted_ids = model.generate(input_features)

    >>> # Decode token ids to text
    >>> transcription = processor.batch_decode(predicted_ids, skip_special_tokens=True)

    >>> transcription[0]
    ' Mr. Quilter is the apostle of the middle classes, and we are glad to welcome his gospel.'

This is the configuration class to store the configuration of a WhisperModel. It is used to instantiate a Whisper model according to the specified arguments, defining the model architecture. Instantiating a configuration with the defaults will yield a similar configuration to that of the Whisper openai/whisper-tiny architecture.

Configuration objects inherit from PretrainedConfig and can be used to control the model outputs. Read the documentation from PretrainedConfig for more information.

Example:

    >>> from transformers import WhisperConfig, WhisperModel

    >>> # Initializing a Whisper tiny style configuration
    >>> configuration = WhisperConfig()

    >>> # Initializing a model (with random weights) from the tiny style configuration
    >>> model = WhisperModel(configuration)

    >>> # Accessing the model configuration
    >>> configuration = model.config

( feature_size = 80 sampling_rate = 16000 hop_length = 160 chunk_length = 30 n_fft = 400 padding_value = 0.0 return_attention_mask = False **kwargs )

Parameters

- feature_size (`int`, optional, defaults to 80) — The feature dimension of the extracted features.
- sampling_rate (`int`, optional, defaults to 16000) — The sampling rate at which the audio files should be digitalized expressed in hertz (Hz).
- hop_length (`int`, optional, defaults to 160) — Length of the overlaping windows for the STFT used to obtain the Mel Frequency coefficients.
- chunk_length (`int`, optional, defaults to 30) — The maximum number of chuncks of `sampling_rate` samples used to trim and pad longer or shorter audio sequences.
- n_fft (`int`, optional, defaults to 400) — Size of the Fourier transform.
- padding_value (`float`, optional, defaults to 0.0) — Padding value used to pad the audio. Should correspond to silences.

Constructs a Whisper feature extractor.

This feature extractor inherits from SequenceFeatureExtractor which contains most of the main methods. Users should refer to this superclass for more information regarding those methods.

This class extracts mel-filter bank features from raw speech using a custom numpy implementation of the `Short Time Fourier Transform` which should match pytorch’s `torch.stft` equivalent.

__call__

< source >

( raw_speech: Union truncation: bool = True pad_to_multiple_of: Optional = None return_tensors: Union = None return_attention_mask: Optional = None padding: Optional = 'max_length' max_length: Optional = None sampling_rate: Optional = None do_normalize: Optional = None device: Optional = 'cpu' return_token_timestamps: Optional = None **kwargs )

Parameters

- raw_speech (`np.ndarray`, `List[float]`, `List[np.ndarray]`, `List[List[float]]`) — The sequence or batch of sequences to be padded. Each sequence can be a numpy array, a list of float values, a list of numpy arrays or a list of list of float values. Must be mono channel audio, not stereo, i.e. single float per timestep.
- truncation (`bool`, optional, default to `True`) — Activates truncation to cut input sequences longer than max_length to max_length.
- pad_to_multiple_of (`int`, optional, defaults to None) — If set will pad the sequence to a multiple of the provided value.

  This is especially useful to enable the use of Tensor Cores on NVIDIA hardware with compute capability `>= 7.5` (Volta), or on TPUs which benefit from having sequence lengths be a multiple of 128.

- return_attention_mask (`bool`, optional) — Whether to return the attention mask. If left to the default, will return the attention mask according to the specific feature_extractor’s default.

  What are attention masks?

  For Whisper models, `attention_mask` should always be passed for batched inference, to avoid subtle bugs.

- return_tensors (`str` or TensorType, optional) — If set, will return tensors instead of list of python integers. Acceptable values are:
  - `'tf'`: Return TensorFlow `tf.constant` objects.
  - `'pt'`: Return PyTorch `torch.Tensor` objects.
  - `'np'`: Return Numpy `np.ndarray` objects.
- sampling_rate (`int`, optional) — The sampling rate at which the `raw_speech` input was sampled. It is strongly recommended to pass `sampling_rate` at the forward call to prevent silent errors and allow automatic speech recognition pipeline.
- padding_value (`float`, optional, defaults to 0.0) — The value that is used to fill the padding values / vectors.
- do_normalize (`bool`, optional, defaults to `False`) — Whether or not to zero-mean unit-variance normalize the input. Normalizing can help to significantly improve the performance of the model.
- device (`str`, optional, defaults to `'cpu'`) — Specifies the device for computation of the log-mel spectrogram of audio signals in the `_torch_extract_fbank_features` method. (e.g., “cpu”, “cuda”)
- return_token_timestamps (`bool`, optional, defaults to `None`) — Whether or not to return the number of frames of the input raw_speech. These num_frames can be used by the model to compute word level timestamps.

Main method to featurize and prepare for the model one or several sequence(s). Implementation uses PyTorch for the STFT computation if available, otherwise a slower NumPy based one.

( config: WhisperConfig )

Parameters

- config (WhisperConfig) — Model configuration class with all the parameters of the model. Initializing with a config file does not load the weights associated with the model, only the configuration. Check out the from_pretrained() method to load the model weights.

transformers.modeling_outputs.Seq2SeqModelOutput or `tuple(torch.FloatTensor)`

Parameters

- input_features (`torch.FloatTensor` of shape `(batch_size, feature_size, sequence_length)`) — Float values mel features extracted from the raw speech waveform. Raw speech waveform can be obtained by loading a `.flac` or `.wav` audio file into an array of type `List[float]` or a `numpy.ndarray`, e.g. via the soundfile library (`pip install soundfile`). To prepare the array into `input_features`, the AutoFeatureExtractor should be used for extracting the mel features, padding and conversion into a tensor of type `torch.FloatTensor`. See call()
- attention_mask (`torch.LongTensor` of shape `(batch_size, sequence_length)`, optional) — Mask to avoid performing SpecAugment data augmentation on padding token indices. Mask values selected in `[0, 1]`:
  - 1 for tokens that are not masked,
  - 0 for tokens that are masked.

  What are attention masks?

- decoder_input_ids (`torch.LongTensor` of shape `(batch_size, target_sequence_length)`, optional) — Indices of decoder input sequence tokens in the vocabulary.

  Indices can be obtained using WhisperTokenizer. See PreTrainedTokenizer.encode() and PreTrainedTokenizer.call() for details.

  What are decoder input IDs?

  Whisper uses the `decoder_start_token_id` as the starting token for `decoder_input_ids` generation. If `past_key_values` is used, optionally only the last `decoder_input_ids` have to be input (see `past_key_values`).

- decoder_attention_mask (`torch.LongTensor` of shape `(batch_size, target_sequence_length)`, optional) — Default behavior: generate a tensor that ignores pad tokens in `decoder_input_ids`. Causal mask will also be used by default.

  If you want to change padding behavior, you should read `modeling_whisper._prepare_decoder_attention_mask` and modify to your needs. See diagram 1 in the BART paper for more information on the default strategy.

- head_mask (`torch.Tensor` of shape `(encoder_layers, encoder_attention_heads)`, optional) — Mask to nullify selected heads of the attention modules in the encoder. Mask values selected in `[0, 1]`:
  - 1 indicates the head is not masked,
  - 0 indicates the head is masked.
- decoder_head_mask (`torch.Tensor` of shape `(decoder_layers, decoder_attention_heads)`, optional) — Mask to nullify selected heads of the attention modules in the decoder. Mask values selected in `[0, 1]`:
  - 1 indicates the head is not masked,
  - 0 indicates the head is masked.
- cross_attn_head_mask (`torch.Tensor` of shape `(decoder_layers, decoder_attention_heads)`, optional) — Mask to nullify selected heads of the cross-attention modules. Mask values selected in `[0, 1]`:
  - 1 indicates the head is not masked,
  - 0 indicates the head is masked.
- encoder_outputs (`tuple(tuple(torch.FloatTensor)`, optional) — Tuple consists of (`last_hidden_state`, optional: `hidden_states`, optional: `attentions`) `last_hidden_state` of shape `(batch_size, sequence_length, hidden_size)`, optional) is a sequence of hidden-states at the output of the last layer of the encoder. Used in the cross-attention of the decoder.
- past_key_values (`EncoderDecoderCache` or `tuple(tuple(torch.FloatTensor))`, optional) — Pre-computed hidden-states that can be used to speed up auto-regressive (sequential) decoding. There are four sets of pre-computed hidden-states: key and values states in the self-attention blocks (2) and in the cross-attention blocks (2). The `past_key_values` are returned when `use_cache=True` is passed or when `config.use_cache=True`

  Two formats are allowed:

  - An EncoderDecoderCache instance;
  - Tuple of `tuple(torch.FloatTensor)` of length `config.n_layers`, with each tuple having 2 tensors of shape `(batch_size, num_heads, sequence_length, embed_size_per_head)`) and 2 additional tensors of shape `(batch_size, num_heads, encoder_sequence_length, embed_size_per_head)`.

  If `past_key_values` are used, the user can optionally input only the last `decoder_input_ids` (those that don’t have their past key value states given to this model) of shape `(batch_size, 1)` instead of all `decoder_input_ids` of shape `(batch_size, sequence_length)`.

- decoder_inputs_embeds (`torch.FloatTensor` of shape `(batch_size, target_sequence_length, hidden_size)`, optional) — Optionally, instead of passing `decoder_input_ids` you can choose to directly pass an embedded representation. If `past_key_values` is used, optionally only the last `decoder_inputs_embeds` have to be input (see `past_key_values`). This is useful if you want more control over how to convert `decoder_input_ids` indices into associated vectors than the model’s internal embedding lookup matrix.
- use_cache (`bool`, optional) — If set to `True`, `past_key_values` key value states are returned and can be used to speed up decoding (see `past_key_values`).
- output_attentions (`bool`, optional) — Whether or not to return the attentions tensors of all attention layers. See `attentions` under returned tensors for more detail.
- output_hidden_states (`bool`, optional) — Whether or not to return the hidden states of all layers. See `hidden_states` under returned tensors for more detail.
- return_dict (`bool`, optional) — Whether or not to return a ModelOutput instead of a plain tuple.
- cache_position (`torch.LongTensor` of shape `(sequence_length)`, optional) — Indices depicting the position of the input sequence tokens in the sequence. It is used to update the cache in the correct position and to infer the complete sequence length.

The WhisperModel forward method, overrides the `__call__` special method.

Although the recipe for forward pass needs to be defined within this function, one should call the `Module` instance afterwards instead of this since the former takes care of running the pre and post processing steps while the latter silently ignores them.

Example:

    >>> import torch
    >>> from transformers import AutoFeatureExtractor, WhisperModel
    >>> from datasets import load_dataset

    >>> model = WhisperModel.from_pretrained("openai/whisper-base")
    >>> feature_extractor = AutoFeatureExtractor.from_pretrained("openai/whisper-base")
    >>> ds = load_dataset("hf-internal-testing/librispeech_asr_dummy", "clean", split="validation")
    >>> inputs = feature_extractor(ds[0]["audio"]["array"], return_tensors="pt")
    >>> input_features = inputs.input_features
    >>> decoder_input_ids = torch.tensor([[1, 1]]) * model.config.decoder_start_token_id
    >>> last_hidden_state = model(input_features, decoder_input_ids=decoder_input_ids).last_hidden_state
    >>> list(last_hidden_state.shape)

The WhisperForConditionalGeneration forward method, overrides the `__call__` special method.

Although the recipe for forward pass needs to be defined within this function, one should call the `Module` instance afterwards instead of this since the former takes care of running the pre and post processing steps while the latter silently ignores them.

Example:

    >>> import torch
    >>> from transformers import AutoProcessor, WhisperForConditionalGeneration
    >>> from datasets import load_dataset

    >>> processor = AutoProcessor.from_pretrained("openai/whisper-tiny.en")
    >>> model = WhisperForConditionalGeneration.from_pretrained("openai/whisper-tiny.en")

    >>> ds = load_dataset("hf-internal-testing/librispeech_asr_dummy", "clean", split="validation")

    >>> inputs = processor(ds[0]["audio"]["array"], return_tensors="pt")
    >>> input_features = inputs.input_features

    >>> generated_ids = model.generate(inputs=input_features)

    >>> transcription = processor.batch_decode(generated_ids, skip_special_tokens=True)[0]

ModelOutput or `torch.LongTensor` or `Dict[str, Any]`

Parameters

- input_features (`torch.Tensor` of shape `(batch_size, feature_size, sequence_length)`, optional) — Float values of log-mel features extracted from the raw speech waveform. The raw speech waveform can be obtained by loading a `.flac` or `.wav` audio file into an array of type `List[float]` or a `numpy.ndarray`, e.g. via the soundfile library (`pip install soundfile`). To prepare the array into `input_features`, the AutoFeatureExtractor should be used for extracting the mel features, padding and conversion into a tensor of type `torch.FloatTensor`. See call() for details.
- generation_config (`~generation.GenerationConfig`, optional) — The generation configuration to be used as base parametrization for the generation call. `**kwargs` passed to generate matching the attributes of `generation_config` will override them. If `generation_config` is not provided, the default will be used, which had the following loading priority: 1) from the `generation_config.json` model file, if it exists; 2) from the model configuration. Please note that unspecified parameters will inherit GenerationConfig’s default values, whose documentation should be checked to parameterize generation.
- logits_processor (`LogitsProcessorList`, optional) — Custom logits processors that complement the default logits processors built from arguments and generation config. If a logit processor is passed that is already created with the arguments or a generation config an error is thrown. This feature is intended for advanced users.
- stopping_criteria (`StoppingCriteriaList`, optional) — Custom stopping criteria that complement the default stopping criteria built from arguments and a generation config. If a stopping criteria is passed that is already created with the arguments or a generation config an error is thrown. This feature is intended for advanced users.
- prefix_allowed_tokens_fn (`Callable[[int, torch.Tensor], List[int]]`, optional) — If provided, this function constraints the beam search to allowed tokens only at each step. If not provided no constraint is applied. This function takes 2 arguments: the batch ID `batch_id` and `input_ids`. It has to return a list with the allowed tokens for the next generation step conditioned on the batch ID `batch_id` and the previously generated tokens `inputs_ids`. This argument is useful for constrained generation conditioned on the prefix, as described in Autoregressive Entity Retrieval.
- synced_gpus (`bool`, optional, defaults to `False`) — Whether to continue running the while loop until max_length (needed for ZeRO stage 3)
- return_timestamps (`bool`, optional) — Whether to return the timestamps with the text. This enables the `WhisperTimestampsLogitsProcessor`.
- task (`str`, optional) — Task to use for generation, either “translate” or “transcribe”. The `model.config.forced_decoder_ids` will be updated accordingly.
- language (`str` or list of `str`, optional) — Language token to use for generation, can be either in the form of `<|en|>`, `en` or `english`. For batched generation, a list of language tokens can be passed. You can find all the possible language tokens in the `model.generation_config.lang_to_id` dictionary.
- is_multilingual (`bool`, optional) — Whether or not the model is multilingual.
- prompt_ids (`torch.Tensor`, optional) — Rank-1 tensor of token IDs created by passing text to `get_prompt_ids()` that is provided as a prompt to each chunk. This can be used to provide or “prompt-engineer” a context for transcription, e.g. custom vocabularies or proper nouns to make it more likely to predict those words correctly. It cannot be used in conjunction with `decoder_start_token_id` as it overwrites this value.
- prompt_condition_type (`str`, optional) — Only relevant for long-form transcription. Condition type of `prompt_ids`. ‘first-segment’ means only the first segment is conditioned on `prompt_ids`. ‘all-segments’ means each segment is conditioned on `prompt_ids`. Make sure to enable `condition_on_prev_tokens` for ‘all-segments’. Defaults to ‘first-segment’. For short-term transcription only ‘first-segment’ is possible.
- condition_on_prev_tokens (`bool`, optional) — Only relevant for long-form transcription. Whether to condition each segment on the previous segment. As shown in the the Whisper paper, this can help to improve performance.
- temperature (`float` or list of `float`, optional) — The temperature to be used for generation. Passing a single `float` value and `do_sample=True` activates generation using sampling. For long-form transcription, temperature fallback can be activated by passing a list of float values such as (0.0, 0.2, 0.4, 0.6, 0.8, 1.0). As shown in the the Whisper paper, this can help to improve performance.
- compression_ratio_threshold (`float`, optional) — Only relevant for long-form transcription. If defined, the zlib compression rate of each segment will be computed. If the compression rate of a segment is higher than `compression_ratio_threshold`, temperature fallback is activated: the generated segment is discarded and the generation is repeated using a higher temperature. The intuition behind this feature is that segments with very high compression rates suffer from a lot of repetition. The unwanted repetition can be reduced by injecting more randomness by increasing the temperature. If `compression_ratio_threshold` is defined make sure that `temperature` is a list of values. A common value for `compression_ratio_threshold` is 1.35. As shown in the the Whisper paper, this can help to improve performance.
- logprob_threshold (`float`, optional) — Only relevant for long-form transcription. If defined, the average log-probability of each segment will be computed. If the log-probability of a given segment is lower than `logprob_threshold`, temperature fallback is activated: the generated segment is discarded and the generation is repeated using a higher temperature. The intuition behind this feature is that segments of low log-probability can be improved by injecting more randomness by increasing the temperature. If `logprob_threshold` is defined make sure that `temperature` is a list of values. A common value for `logprob_threshold` is -1.0. As shown in the the Whisper paper, this can help to improve performance.
- no_speech_threshold (`float`, optional) — Only relevant for long-form transcription. If defined, the “no-speech” token combined with the `logprob_threshold` is used to determine whether a segment contains only silence. In this case, the transcription for this segment is skipped. As shown in the the Whisper paper, this can help to improve performance.
- num_segment_frames (`int`, optional) — The number of frames a single segment is made of. If not defined, `num_segment_frames` defaults to the model’s stride times the maximum input length.
- attention_mask (`torch.Tensor`, optional) — `attention_mask` needs to be passed when doing long-form transcription using a batch size > 1.
- time_precision (`int`, optional, defaults to 0.02) — The duration of output token in seconds. E.g. 0.02 means that a generated token on average accounts for 20 ms.
- return_token_timestamps (`bool`, optional) — Whether to return token-level timestamps with the text. This can be used with or without the `return_timestamps` option. To get word-level timestamps, use the tokenizer to group the tokens into words.
- return_segments (`bool`, optional, defaults to `False`) — Whether to additionally return a list of all segments. Note that this option can only be enabled when doing long-form transcription.
- return_dict_in_generate (`bool`, optional, defaults to `False`) — Whether or not to return a ModelOutput instead of just returning the generated tokens. Note that when doing long-form transcription, `return_dict_in_generate` can only be enabled when `return_segments` is set True. In this case the generation outputs of each segment is added to each segment.
- kwargs (`Dict[str, Any]`, optional) — Ad hoc parametrization of `generate_config` and/or additional model-specific kwargs that will be forwarded to the `forward` function of the model. If the model is an encoder-decoder model, encoder specific kwargs should not be prefixed and decoder specific kwargs should be prefixed with decoder_.

Returns

ModelOutput or `torch.LongTensor` or `Dict[str, Any]`

A ModelOutput (if `return_dict_in_generate=True` or when `config.return_dict_in_generate=True`) or a `torch.FloatTensor` or a dict of segments when `return_segments=True`.

If the passed input is > 30 seconds / > 3000 mel input features and `return_segments=True` then a dictionary of generated sequence ids, called `sequences` and a list of each generated segment is returned.

else if the passed input is <= 30 seconds / >= 3000 mel input features, the possible ModelOutput types are:

- GenerateEncoderDecoderOutput,
- GenerateBeamEncoderDecoderOutput

else only the generated output sequence ids are returned.

Transcribes or translates log-mel input features to a sequence of auto-regressively generated token ids.

Most generation-controlling parameters are set in `generation_config` which, if not passed, will be set to the model’s default generation configuration. You can override any `generation_config` by passing the corresponding parameters to generate(), e.g. `.generate(inputs, num_beams=4, do_sample=True)`.

For an overview of generation strategies and code examples, check out the following guide.

Example:

- Longform transcription: To transcribe or translate audios longer than 30 seconds, process the audio files without truncation and pass all mel features at once to generate.

    >>> import torch
    >>> from transformers import AutoProcessor, WhisperForConditionalGeneration
    >>> from datasets import load_dataset, Audio

    >>> processor = AutoProcessor.from_pretrained("openai/whisper-tiny.en")
    >>> model = WhisperForConditionalGeneration.from_pretrained("openai/whisper-tiny.en")
    >>> model.cuda()
    >>> # load audios > 30 seconds
    >>> ds = load_dataset("distil-whisper/meanwhile", "default")["test"]
    >>> # resample to 16kHz
    >>> ds = ds.cast_column("audio", Audio(sampling_rate=16000))
    >>> # take first 8 audios and retrieve array
    >>> audio = ds[:8]["audio"]
    >>> audio = [x["array"] for x in audio]

    >>> # make sure to NOT truncate the input audio, to return the `attention_mask` and to pad to the longest audio
    >>> inputs = processor(audio, return_tensors="pt", truncation=False, padding="longest", return_attention_mask=True, sampling_rate=16_000)
    >>> inputs = inputs.to("cuda", torch.float32)

    >>> # transcribe audio to ids
    >>> generated_ids = model.generate(**inputs)

    >>> transcription = processor.batch_decode(generated_ids, skip_special_tokens=True)
    >>> transcription[0]
    " Folks, if you watch the show, you know, I spent a lot of time right over there. Patiently and astutely scrutinizing the boxwood and mahogany chest set of the day's biggest stories developing the central headline pawns, definitely maneuvering an oso topical night to F6, fainting a classic Sicilian, nade door variation on the news, all the while seeing eight moves deep and patiently marshalling the latest press releases into a fisher's shows in Lip Nitsky attack that culminates in the elegant lethal slow-played, all-passant checkmate that is my nightly monologue. But sometimes, sometimes, folks, I. CHEERING AND APPLAUSE Sometimes I startle away, cubside down in the monkey bars of a condemned playground on a super fun site. Get all hept up on goofballs. Rummage that were discarded tag bag of defective toys. Yank out a fist bowl of disembodied doll limbs, toss them on a stained kid's place mat from a defunct dennies. set up a table inside a rusty cargo container down by the Wharf and challenged toothless drifters to the godless bughouse blitz of tournament that is my segment. Meanwhile."

- Shortform transcription: If passed mel input features are < 30 seconds, the whole audio will be transcribed with a single call to generate.

    >>> import torch
    >>> from transformers import AutoProcessor, WhisperForConditionalGeneration
    >>> from datasets import load_dataset

    >>> processor = AutoProcessor.from_pretrained("openai/whisper-tiny.en")
    >>> model = WhisperForConditionalGeneration.from_pretrained("openai/whisper-tiny.en")

    >>> ds = load_dataset("hf-internal-testing/librispeech_asr_dummy", "clean", split="validation")

    >>> inputs = processor(ds[0]["audio"]["array"], return_tensors="pt")
    >>> input_features = inputs.input_features

    >>> generated_ids = model.generate(inputs=input_features)

    >>> transcription = processor.batch_decode(generated_ids, skip_special_tokens=True)[0]
    >>> transcription

class transformers.WhisperForCausalLM

< source >

( config )

Parameters

- config (WhisperConfig) — Model configuration class with all the parameters of the model. Initializing with a config file does not load the weights associated with the model, only the configuration. Check out the from_pretrained() method to load the model weights.

Whisper decoder with a language modeling head on top (linear layer with weights tied to the input embeddings).

This model inherits from PreTrainedModel. Check the superclass documentation for the generic methods the library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads etc.)

This model is also a PyTorch torch.nn.Module subclass. Use it as a regular PyTorch Module and refer to the PyTorch documentation for all matter related to general usage and behavior.

transformers.modeling_outputs.CausalLMOutputWithCrossAttentions or `tuple(torch.FloatTensor)`

Parameters

- attention_mask (`torch.Tensor` of shape `(batch_size, sequence_length)`, optional) — Mask to avoid performing attention on padding token indices. Mask values selected in `[0, 1]`:
  - 1 for tokens that are not masked,
  - 0 for tokens that are masked. What are attention masks?
- encoder_outputs (`torch.FloatTensor` of shape `(batch_size, sequence_length, hidden_size)`, optional) — Sequence of hidden-states at the output of the last layer of the encoder. Used in the cross-attention if the model is configured as a decoder.
- head_mask (`torch.Tensor` of shape `(decoder_layers, decoder_attention_heads)`, optional) — Mask to nullify selected heads of the attention modules. Mask values selected in `[0, 1]`:
  - 1 indicates the head is not masked,
  - 0 indicates the head is masked.
- cross_attn_head_mask (`torch.Tensor` of shape `(decoder_layers, decoder_attention_heads)`, optional) — Mask to nullify selected heads of the cross-attention modules. Mask values selected in `[0, 1]`:

The two additional tensors are only required when the model is used as a decoder in a Sequence to Sequence model. Contains pre-computed hidden-states (key and values in the self-attention blocks and in the cross-attention blocks) that can be used (see `past_key_values` input) to speed up sequential decoding. If `past_key_values` are used, the user can optionally input only the last `decoder_input_ids` (those that don’t have their past key value states given to this model) of shape `(batch_size, 1)` instead of all `decoder_input_ids` of shape `(batch_size, sequence_length)`.
- inputs_embeds (`torch.FloatTensor` of shape `(batch_size, sequence_length, hidden_size)`, optional) — Optionally, instead of passing `input_ids` you can choose to directly pass an embedded representation.

Although the recipe for forward pass needs to be defined within this function, one should call the `Module` instance afterwards instead of this since the former takes care of running the pre and post processing steps while the latter silently ignores them.

transformers.modeling_tf_outputs.TFSeq2SeqModelOutput or `tuple(tf.Tensor)`

Parameters

- input_features (`tf.Tensor` of shape `(batch_size, feature_size, sequence_length)`) — Float values of fbank features extracted from the raw speech waveform. Raw speech waveform can be obtained by loading a `.flac` or `.wav` audio file into an array of type `List[float]` or a `numpy.ndarray`, e.g. via the soundfile library (`pip install soundfile`). To prepare the array into `input_features`, the AutoFeatureExtractor should be used for extracting the fbank features, padding and conversion into a tensor of type `tf.Tensor`. See call()
- decoder_input_ids (`tf.Tensor` of shape `(batch_size, target_sequence_length)`, optional) — Indices of decoder input sequence tokens in the vocabulary.

  Indices can be obtained using `SpeechToTextTokenizer`. See PreTrainedTokenizer.encode() and PreTrainedTokenizer.call() for details.

  What are decoder input IDs?

  SpeechToText uses the `eos_token_id` as the starting token for `decoder_input_ids` generation. If `past_key_values` is used, optionally only the last `decoder_input_ids` have to be input (see `past_key_values`).

- decoder_attention_mask (`tf.Tensor` of shape `(batch_size, target_sequence_length)`, optional) — Default behavior: generate a tensor that ignores pad tokens in `decoder_input_ids`. Causal mask will also be used by default.

  If you want to change padding behavior, you should read `modeling_whisper._prepare_decoder_attention_mask` and modify to your needs. See diagram 1 in the paper for more information on the default strategy.

- head_mask (`tf.Tensor` of shape `(encoder_layers, encoder_attention_heads)`, optional) — Mask to nullify selected heads of the attention modules in the encoder. Mask values selected in `[0, 1]`:
  - 1 indicates the head is not masked,
  - 0 indicates the head is masked.
- decoder_head_mask (`tf.Tensor` of shape `(decoder_layers, decoder_attention_heads)`, optional) — Mask to nullify selected heads of the attention modules in the decoder. Mask values selected in `[0, 1]`:
  - 1 indicates the head is not masked,
  - 0 indicates the head is masked.
- cross_attn_head_mask (`tf.Tensor` of shape `(decoder_layers, decoder_attention_heads)`, optional) — Mask to nullify selected heads of the cross-attention modules. Mask values selected in `[0, 1]`:
  - 1 indicates the head is not masked,
  - 0 indicates the head is masked.
- encoder_outputs (`tuple(tuple(tf.Tensor)`, optional) — Tuple consists of (`last_hidden_state`, optional: `hidden_states`, optional: `attentions`) `last_hidden_state` of shape `(batch_size, sequence_length, hidden_size)`, optional) is a sequence of hidden-states at the output of the last layer of the encoder. Used in the cross-attention of the decoder.
- past_key_values (`tuple(tuple(tf.Tensor))`, optional, returned when `use_cache=True` is passed or when `config.use_cache=True`) — Tuple of `tuple(tf.Tensor)` of length `config.n_layers`, with each tuple having 2 tensors of shape `(batch_size, num_heads, sequence_length, embed_size_per_head)`) and 2 additional tensors of shape `(batch_size, num_heads, encoder_sequence_length, embed_size_per_head)`.

  Contains pre-computed hidden-states (key and values in the self-attention blocks and in the cross-attention blocks) that can be used (see `past_key_values` input) to speed up sequential decoding.

  If `past_key_values` are used, the user can optionally input only the last `decoder_input_ids` (those that don’t have their past key value states given to this model) of shape `(batch_size, 1)` instead of all `decoder_input_ids` of shape `(batch_size, sequence_length)`.

- decoder_inputs_embeds (`tf.Tensor` of shape `(batch_size, target_sequence_length, hidden_size)`, optional) — Optionally, instead of passing `decoder_input_ids` you can choose to directly pass an embedded representation. If `past_key_values` is used, optionally only the last `decoder_inputs_embeds` have to be input (see `past_key_values`). This is useful if you want more control over how to convert `decoder_input_ids` indices into associated vectors than the model’s internal embedding lookup matrix.
- use_cache (`bool`, optional) — If set to `True`, `past_key_values` key value states are returned and can be used to speed up decoding (see `past_key_values`).
- output_attentions (`bool`, optional) — Whether or not to return the attentions tensors of all attention layers. See `attentions` under returned tensors for more detail.

The `FlaxWhisperPreTrainedModel` forward method, overrides the `__call__` special method.

Although the recipe for forward pass needs to be defined within this function, one should call the `Module` instance afterwards instead of this since the former takes care of running the pre and post processing steps while the latter silently ignores them.

Example:

    >>> from transformers import AutoTokenizer, FlaxWhisperModel

    >>> tokenizer = AutoTokenizer.from_pretrained("openai/whisper-tiny")
    >>> model = FlaxWhisperModel.from_pretrained("openai/whisper-tiny")

    >>> inputs = tokenizer("Hello, my dog is cute", return_tensors="jax")
    >>> outputs = model(**inputs)

    >>> last_hidden_states = outputs.last_hidden_state

< source >

( config: WhisperConfig input_shape: Tuple = None seed: int = 0 dtype: dtype = <class 'jax.numpy.float32'> _do_init: bool = True gradient_checkpointing: bool = False **kwargs )

Parameters

- config (WhisperConfig) — Model configuration class with all the parameters of the model. Initializing with a config file does not load the weights associated with the model, only the configuration. Check out the from_pretrained() method to load the model weights.
- dtype (`jax.numpy.dtype`, optional, defaults to `jax.numpy.float32`) — The data type of the computation. Can be one of `jax.numpy.float32`, `jax.numpy.float16` (on GPUs) and `jax.numpy.bfloat16` (on TPUs). This can be used to enable mixed-precision training or half-precision inference on GPUs or TPUs. If specified all the computation will be performed with the given `dtype`. Note that this only specifies the dtype of the computation and does not influence the dtype of model parameters. If you wish to change the dtype of the model parameters, see to_fp16() and to_bf16().

The Whisper Model with a language modeling head. This model inherits from FlaxPreTrainedModel. Check the superclass documentation for the generic methods the library implements for all its models (such as downloading or saving, resizing the input embeddings, pruning heads etc.) This model is also a Flax Linen flax.nn.Module subclass. Use it as a regular Flax Module and refer to the Flax documentation for all matter related to general usage and behavior. Finally, this model supports inherent JAX features such as:

- Just-In-Time (JIT) compilation
- Automatic Differentiation
- Vectorization
- Parallelization

transformers.modeling_flax_outputs.FlaxSeq2SeqLMOutput or `tuple(torch.FloatTensor)`

Parameters

- input_features (`numpy.ndarray` of shape `(batch_size, feature_size, sequence_length)`) — Float values mel features extracted from the raw speech waveform. Raw speech waveform can be obtained by loading a `.flac` or `.wav` audio file into an array of type `List[float]` or a `numpy.ndarray`, e.g. via the soundfile library (`pip install soundfile`). To prepare the array into `input_features`, the WhisperFeatureExtractor should be used for extracting the features, padding and conversion into a tensor of type `numpy.ndarray`. See call()
- attention_mask (`numpy.ndarray` of shape `(batch_size, sequence_length)`, optional) — Whisper does not support masking of the `input_features`, this argument is preserved for compatibility, but is not used. By default the silence in the input log mel spectrogram are ignored.
- decoder_input_ids (`numpy.ndarray` of shape `(batch_size, target_sequence_length)`, optional) — Indices of decoder input sequence tokens in the vocabulary. Indices can be obtained using WhisperTokenizer. See PreTrainedTokenizer.encode() and PreTrainedTokenizer.call() for details. What are decoder input IDs? Whisper uses the `decoder_start_token_id` as the starting token for `decoder_input_ids` generation.
- decoder_attention_mask (`numpy.ndarray` of shape `(batch_size, target_sequence_length)`, optional) — Default behavior: generate a tensor that ignores pad tokens in `decoder_input_ids`. Causal mask will also be used by default. If you want to change padding behavior, you should modify to your needs. See diagram 1 in the paper for more information on the default strategy.
- position_ids (`numpy.ndarray` of shape `(batch_size, sequence_length)`, optional) — Whisper does not use `position_ids` in the encoder as `input_features` is always the same size and doesn’t use masking, but this argument is preserved for compatibility. By default the silence in the input log mel spectrogram are ignored.
- decoder_position_ids (`numpy.ndarray` of shape `(batch_size, sequence_length)`, optional) — Indices of positions of each decoder input sequence tokens in the position embeddings. Selected in the range `[0, config.max_position_embeddings - 1]`.
- output_attentions (`bool`, optional) — Whether or not to return the attentions tensors of all attention layers. See `attentions` under returned tensors for more detail.
- output_hidden_states (`bool`, optional) — Whether or not to return the hidden states of all layers. See `hidden_states` under returned tensors for more detail.
- return_dict (`bool`, optional) — Whether or not to return a ModelOutput instead of a plain tuple.
