Abstract

L'invention concerne un procédé et un dispositif de réduction du bruit dans des signaux vocaux, utilisant des connaissances a priori la production de la parole et des connaissances de dynamique de la parole, telles que des connaissances portant sur la production de sons dans les régions de la bouche et de la gorge. Le procédé et le dispositif de l'invention utilisent également un nouveau modèle basé sur un algorithme de soustraction spectrale, consistant à remplacer une partie du signal original contenant des sons par des impulsions de synthèse, ce qui améliore la réduction du bruit sans affecter les composantes (vocales) du signal recherchées. Le procédé, qui peut être utilisé pour un SNR faible (SNR<10 dB), résulte avantageux lorsqu'on l'utilise dans le cadre de communications utilisant des téléphones cellulaires.
