_DESCRIPTION = """\
The Snow Mountain dataset contains the audio recordings (in .mp3 format) and the corresponding text of The Bible 
in 11 Indian languages. The recordings were done in a studio setting by native speakers. Each language has a single 
speaker in the dataset. Most of these languages are geographically concentrated in the Northern part of India around 
the state of Himachal Pradesh. Being related to Hindi they all use the Devanagari script for transcription.
