TIDIGITS was developed by Texas Instruments, Inc. (TI) and consists of approximately 13 hours of digit sequences in English spoken by over 300 men, women, and children. This corpus contains speech which was originally designed and collected at TI for the purpose of designing and evaluating algorithms for speaker-independent recognition of connected digit sequences.


The corpus was collected at TI in 1982 in a quiet acoustic enclosure using an Electro-Voice RE-16 Dynamic Cardiod microphone, digitized at 20kHz. The waveform files are single channel, 16-bit files in the NIST SPHERE format. There are 326 speakers (111 men, 114 women, 50 boys and 51 girls) each pronouncing 77 digit sequences. Each speaker group is partitioned into test and training subsets. Speaker metadata includes gender, age, and dialect.



As of April, 2015, TIDIGITS is also available in flac compressed wav. This package is available to licensees as an additional download. Not included in this version are the folders relating to handling the shortened sphere files of the original corpus.
