Speaker and session variability in speech processing
FY 2007-08
Summary
Two of the principal problems in speech technologyare speaker recognition (who is speaking?) and speechrecognition (what is being said?). These problemshave resisted solution because of the numerous typesof variability in speech. For example, the performance ofspeaker recognition systems degrades as a resultof channel and microphone effects and careful modelingis needed to distinguish these nuisance effects from aspectsof the speech signal which are useful in discriminatingbetween speakers. In speech recognition on the other hand,variation betweenspeakers is considered to be a nuisance and the only type of variabilitywhich is of real interest is phonetic variability.This proposal is concerned with developing newstatistical methods of modeling speaker and channel variation using`hidden variables' which I call speaker and channel factors.The techniques that I am developing are purely statistical soit is hard to say exactly what the hidden variables represent butit is reasonable to surmise that they capture features such asa speaker's age and sex, electrical noise in transmission channels andordinary background acoustic noise.
