## Dataset Summary

Introducing [**Bud500**](https://huggingface.co/datasets/linhtran92/viet_bud500), a comprehensive Vietnamese speech corpus designed to support ASR research community. With aprroximately **500 hours** of audio, it covers a broad spectrum of topics including podcast, travel, book, food, and so on, while spanning accents from Vietnam's North, South, and Central regions. Derived from free public audio resources, this publicly accessible dataset is designed to significantly enhance the work of developers and researchers in the field of speech recognition.

The corpus was prepared by `VietAI` research team, a non-profit organization with the mission of nurturing AI talents and building a community of world-class AI experts in Vietnam.

## Dataset Structure

A typical data point comprises the Audio object dict `audio` and its `transcription`.

```
{'audio': {'path': None,
           'array': array([0.00125122, 0.00228882, 0.00213623, ..., 0.00354004, 0.00442505, 0.00650024]),
           'sampling_rate': 16000},
 'transcription': 'ai cho phép em uống nhiều rượu như vậy'} 
```

### Data Fields

- `audio`: A dictionary containing the path to the downloaded audio file, the decoded audio array, and the sampling rate. Note that when accessing the audio column: `dataset[0]["audio"]` the audio file is automatically decoded and resampled to `dataset.features["audio"].sampling_rate`. Decoding and resampling of a large number of audio files might take a significant amount of time. Thus it is important to first query the sample index before the `"audio"` column, *i.e.* `dataset[0]["audio"]` should **always** be preferred over `dataset["audio"][0]`.

- `transcription`: textual form of the audio content.

### Data Splits

The speech material has been subdivided into portions for train, test and validation.

| Total size: 98Gb | Train  | Validation  |  Test  |
| ---------------- | -----  | ----------- | ------ |
| Samples          | 634158 |     7500    |  7500  |  
| Duration         | ~500h  |    ~5.46h   | ~5.46h |
