Title (EN) MULTI-SENSORY SPEECH ENHANCEMENT USING A SPEECH-STATE MODEL
(FR) AMELIORATION VOCALE MULTIDETECTION PAR MODELE D'ETAT VOCAL
Abstract:
(EN) A method and apparatus determine a likelihood of a speech state based on an alternative sensor signal (316) and an air conduction microphone signal (318). The likelihood of the speech state is used, together with the alternative sensor signal and the air conduction microphone signal, to estimate (322) a clean speech value for a clean speech signal (324).
(FR) Procédé et dispositif permettant de déterminer la probabilité d'un état de parole sur la base d'un signal de détecteur de substitution et d'un signal de microphone en conduction aérienne. On utilise cette probabilité et les deux signaux considérés pour estimer une valeur vocale propre correspondant à un signal vocal propre.
