Abstract

This paper presented an adaptation approach based on Baum-Welch algorithm method. This method applies the same framework as they are used for training speech recognizers with abundant training data. The Baum-Welch adaptation method adapted to all the parameters of the hidden markov models (HMM) with adaptation data. If large amount of adaptation data is available, these methods could gradually approximate the speaker-dependent ones. The approach is evaluated through the phoneme recognition task on the TIMIT corpus. On the speaker adaptation experiments, up to 91.48% recognition rate is achieved.
