Dataset Description

97:43:54 Hours | 62.2 GB speech data | 1916 Speakers | 1,916 Audio segments | 48 kHz | 16 bit wav. 


 

The LDC-IL Multi-Lingual Raw Speech Corpus dataset is extracted from the raw speech corpora published by LDC-IL in various Indian languages. This dataset is built to address the needs of some applications like language identifier modules where multiple language samples are a requirement, to explore cross-linguistic variations and diatopic comparison to determine what generalizations are possible about the types of variable features, to build multilingual phoneme set and models etc.

The Multi-Lingual speech dataset sampling is taken from the content type of ‘Creative Text-T2’ which is extracted mainly from literary sources. The creative text of the LDC-IL Speech dataset comprises of essays or short stories. One of these essays or short stories, selected randomly from a data set, is assigned to a speaker for reading out. The same story may be read out by multiple speakers.
