This corpus contains speech which was originally designed and collected at Texas Instruments, Inc. (TI) for the purpose of designing and evaluating algorithms for speaker-independent recognition of connected digit sequences. 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.

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 in the NIST SPHERE format.

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.
