This version of the TIMIT Acoustic-Phonetic Continuous Speech Corpus (LDC93S1) has all the waveform files formatted with ms-wav / RIFF headers, to make the corpus more accessible to a wider audience.
The TIMIT corpus of read speech is designed to provide speech data for
acoustic-phonetic studies and for the development and evaluation of
automatic speech recognition systems. TIMIT contains broadband
recordings of 630 speakers of eight major dialects of American English,
each reading ten phonetically rich sentences. The TIMIT corpus
includes time-aligned orthographic, phonetic and word transcriptions
as well as a 16-bit, 16kHz speech waveform file for each utterance.
Corpus design was a joint effort among the Massachusetts Institute of
Technology (MIT), SRI International (SRI) and Texas Instruments, Inc.
(TI). The speech was recorded at TI, transcribed at MIT and verified
and prepared for CD-ROM production by the National Institute of
Standards and Technology (NIST).
The TIMIT corpus transcriptions have been hand verified. Test and
training subsets, balanced for phonetic and dialectal coverage, are
specified. Tabular computer-searchable information is included as
well as written documentation.
