Dataset Card for LibriVox Indonesia 1.0
Dataset Summary
The LibriVox Indonesia dataset consists of MP3 audio and a corresponding text file we generated from the public domain audiobooks LibriVox. 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.

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
