This CD-ROM contains a corpus of speech which was originally designed and collected at Texas Instruments, Inc. (TI) in 1980 and used initially in performance assessment tests of isolated-word speaker-dependent technology. (See "Speech Recognition: Turning Theory to Practice" by G. R. Doddington and T. B. Schalk, in IEEE Spectrum, Vol. 18, No. 9, September 1981.) The 46-word vocabulary consists of two sub-vocabularies: (1) the TI 20-word vocabulary (consisting of the digits zero through nine plus the words "enter," "erase," "go," "help," "no," "rubout," "repeat," "stop," "start," and "yes" as well as (2) the TI 26-word "alphabet set" (consisting of the letters "a" through "z"). The corpus contains read utterances from 16 speakers (eight males and eight females) each speaking 26 utterances of the 46-word vocabulary: 16 tokens designated as training and ten as test. The corpus was collected at Texas Instruments in a quiet acoustic enclosure using an Electro-Voice RE-16 Dynamic Cardiod microphone at 12.5kHz sample rate with 12-bit quantization. The files are in NIST SPHERE format and have a ".wav" filename extension.
