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.
