### Dataset Summary

ASCEND (A Spontaneous Chinese-English Dataset) introduces a high-quality resource of spontaneous multi-turn conversational dialogue Chinese-English code-switching corpus collected in Hong Kong. ASCEND consists of 10.62 hours of spontaneous speech with a total of ~12.3K utterances. The corpus is split into 3 sets: training, validation, and test with a ratio of 8:1:1 while maintaining a balanced gender proportion on each set.

### Supported Tasks and Leaderboards

Code-switching

### Languages

Chinese and English

## Usage

To obtain the full dataset (complete with train, validation, and test set), simply run this:

```
import datasets
dataset = datasets.load_dataset("CAiRE/ASCEND")
```

## Dataset Structure

A typical data point comprises the path to the audio file, the loaded audio array, and its transcription. Additional fields include datapoint id, duration, language, speaker id, session id, and topic.
