We present a two-channel technique for improving speech analysis in certain applications. One channel is the signal from an electroglottograph (EGG), which monitors the vibratory motion of the vocal folds. The other channel is the speech signal obtained from a conventional microphone. We show how the EGG can be used as a tool for validating speech processing algorithms and estimating possible lower bounds for both computation and performance of these algorithms, particularly closed-phase speech… CONTINUE READING
