4 - Débruitage de parole par un filtrage utilisant l'image du locuteur. Une étude de faisabilité
1996
Since speech is both auditory and visual, visual cues could compensate to a certain extent the deficiency of auditory ones, in orde r
to improve man-machine communication and telecommunication systems . This paper deals with a noise reduction method base d
on speech enhancement with adaptive filters estimated from the speaker's lip pattern . We first present the two selected filtering
techniques, and then the tool we used to predict the filter pattern from the lip shape . The whole noise reduction system is tested i n
the context of stationary vowels including a first kick into the problem of non-visible gestures . The results of perceptual tests are
quite promising and allow us to validate the basic principles of our system, which should be tested with more complex stimuli i n
the future .
