TIMIT acoustic-phonetic speech corpus

A large American-English speech corpus that resulted from the joint efforts of several American research sites.

The TIMIT corpus contains a total of 6300 sentences, 10 sentences spoken by 630 speakers selected from 8 major dialect regions of the USA. 70% of the speakers are male, 30% are female.

The text corpus design was done by the Massachusetts Institute of Technology (MIT), Stanford Research Institute and Texas Instruments (TI). The speech was recorded at TI, transcribed at MIT, and has been maintained, verified and prepared for CDROM production by the American National Institute of Standards and Technology (NIST) (Lamel et al. (1986)).
