Speaker independent digit recognition with reference frame-specific distance measures

This work defines novel distance measures for speech recognition which: 1. Model the statistical interaction between adjacent speech frames, 2. Model the statistical characteristics of different speech sounds individually, 3. Are specifically designed to differentiate between confusable speech sounds. Speaker independent recognition tests performed on the Texas Instruments multi-dialect isolated digit data base give substitution rates as low as 0.6 % with a vocabulary of 11 digits.
