Title (EN) SYSTEMS, METHODS, AND APPARATUS FOR MULTI-MICROPHONE BASED SPEECH ENHANCEMENT
(FR) SYSTÈMES, PROCÉDÉS ET APPAREILS D'AMÉLIORATION VOCALE À PLUSIEURS MICROPHONES
Abstract:
(EN) Systems, methods, and apparatus for processing an M-channel input signal are described that include outputting a signal produced by a selected one among a plurality of spatial separation filters. Applications to separating an acoustic signal from a noisy environment are described, and configurations that may be implemented on a multi-microphone handheld device are also described.
(FR) L'invention concerne des systèmes, des procédés et des appareils de traitement d'un signal d'entrée sur canal M, qui comprennent la fourniture d'un signal délivré par un parmi plusieurs filtres de séparation spatiale. Des applications pour la séparation d'un signal acoustique d'un environnement bruyant sont décrites et des configurations qui peuvent être mises en oeuvre sur un dispositif manuel à plusieurs microphones sont également décrites.
