LibriVox Spanish consists of approximately 73 hours of Spanish read speech and transcripts. The audio data was taken from Spanish audiobooks developed by LibriVox, a non-profit project that creates audiobooks from public domain works. The transcripts were developed for this release.


The audio is comprised of sentences from 300 books read by 154 speakers (77 men and 77 women). Audio files were manually segmented and are between three and ten seconds in length. Native Spanish speakers transcribed the audio data.

Audio is presented as 16kHz, 16-bit, single channel flac files. When uncompressed, they produce PCM wav files.

Transcripts are contained in a single plain text file encoded as UTF-8. Speaker metadata is also provided.
