## Dataset Summary
The origin dataset from: [PhoST](https://github.com/VinAIResearch/PhoST)

A speech-to-text translation dataset with source audio in English and target sentences in Vietnamese.

```
{'path': 'stvi/train/waves/315814.wav', 'audio': {'path': 'stvi/train/waves/315814.wav', 'array': array([-0.0050354 , -0.00296021, -0.00549316, ..., -0.0085144 ,
       -0.00686646, -0.00018311]), 'sampling_rate': 16000}, 'sentence': 'tôi cảm thấy bẽ mặt và xấu hổ đến mức tôi chạy ngay về nhà với mẹ và trách phạt bà vì để tôi mặc cái áo gớm guốc'}
```

### Data Fields
- path: The path to the audio file
- audio: A dictionary containing the path to the downloaded audio file, the decoded audio array, and the sampling rate.
