ABSTRACT

In this paper we present a hybrid multilayer perceptron (MLP)/hidde
arkov model (HMM) speaker­independent continuous­speech recogni­
b
tion system, in which the advantages of both approaches are combined
y using MLPs to estimate the state­dependent observation probabilities
p
of an HMM. New MLP architectures and training procedures are
resented which allow the modeling of multiple distributions for phonetic
