Abstract(in English) | Surrounding noise is one of the most serious problems to realize a speech recognition system.Because noise affects the performance even if its level is low.On the other hand,human being can easily recognize what speech means when noise has comparable level with speech.This means the human auditory system has some mochanisms to reduce the effect of noise.We have used masking model based on psychophysical experiments,as a front-end of speech recognition system which simulates voice controller of television set.In this paper,we propose a new parameter extraction method using a digital cochlear model instead of masking model.The model consists of the middle ear and the mechanical motion of the cochlea.The experiments are carried out on condition that the proposed method is implemented in the voice controller of television set. |
