the content of the speech in various conditions and transform from speech
to text automatically. Based on human hearing perception mechanism, we
propose a decomposition method using independent parallel subbands for
speech recognition. In this method, wavelet processing is introduced into
Hidden Markov Model (HMM) and Fuzzy Neural Network (FNN) is used to improve
the convergence speed and to avoid local optimal in speech detection.
Experiment results show that the proposed hybrid speech recognition model
is more robust when noise presents. We combine the dynamic modeling of
CDHMM and the classification capability of fuzzy neutral network, this
has been a hot research area in recent years and can be applied to speech-text
transform devices.]]>Allen, J.B.,19944567577Bershtein, L.S. and S.M. Kovalev,20046899904Bourlard, H. and S. Dupont,19971997pp: 12511254Cui, M.,20042799102Desai, V., A. Dibazar, T.W. Berger and S.
