### Dataset Summary
The LibriVox Indonesia dataset consists of MP3 audio and a corresponding text file we generated from the public 
domain audiobooks [LibriVox](https://librivox.org/). We collected only languages in Indonesia for this dataset. 
The original LibriVox audiobooks or sound files' duration varies from a few minutes to a few hours. Each audio 
file in the speech dataset now lasts from a few seconds to a maximum of 20 seconds. 

We converted the audiobooks to speech datasets using the forced alignment software we developed. It supports 
multilingual, including low-resource languages, such as Acehnese, Balinese, or Minangkabau. We can also use it 
for other languages without additional work to train the model.

The dataset currently consists of 8 hours in 7 languages from Indonesia. We will add more languages or audio files
as we collect them.

### Languages
```
Acehnese, Balinese, Bugisnese, Indonesian, Minangkabau, Javanese, Sundanese
```

## Dataset Structure
### Data Instances
A typical data point comprises the `path` to the audio file and its `sentence`. Additional fields include 
`reader` and `language`.
```python
{
  'path': 'librivox-indonesia/sundanese/universal-declaration-of-human-rights/human_rights_un_sun_brc_0000.mp3',
  'language': 'sun',
  'reader': '3174',
  'sentence': 'pernyataan umum ngeunaan hak hak asasi manusa sakabeh manusa',
  'audio': {
    'path': 'librivox-indonesia/sundanese/universal-declaration-of-human-rights/human_rights_un_sun_brc_0000.mp3', 
    'array': array([-0.00048828, -0.00018311, -0.00137329, ...,  0.00079346, 0.00091553,  0.00085449], dtype=float32), 
    'sampling_rate': 44100
  }, 
}
```

### Data Fields
`path` (`string`): The path to the audio file

`language` (`string`): The language of the audio file

`reader` (`string`): The reader Id in LibriVox

`sentence` (`string`): The sentence the user read from the book.

`audio` (`dict`): 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]`.

### Data Splits
The speech material has only train split.
