Abstract:
(EN) According to some aspects, a system for detecting a designated wake-up word is provided, the system comprising a plurality of microphones to detect acoustic information from a physical space having a plurality of acoustic zones, at least one processor configured to receive a first acoustic signal representing the acoustic information received by the plurality of microphones, process the first acoustic signal to identify content of the first acoustic signal originating from each of the plurality of acoustic zones, provide a plurality of second acoustic signals, each of the plurality of second acoustic signals substantially corresponding to the content identified as originating from a respective one of the plurality of acoustic zones, and performing automatic speech recognition on each of the plurality of second acoustic signals to determine whether the designated wake-up word was spoken.
(FR) Selon certains aspects, l'invention concerne un système pour détecter un mot de réveil désigné, le système comprenant une pluralité de microphones permettant de détecter des informations acoustiques provenant d'un espace physique ayant une pluralité de zones acoustiques, au moins un processeur configuré pour recevoir un premier signal acoustique représentant les informations acoustiques reçues par la pluralité de microphones, traiter le premier signal acoustique pour identifier le contenu du premier signal acoustique provenant de chacune de la pluralité de zones acoustiques, fournir une pluralité de seconds signaux acoustiques, chacun de la pluralité de seconds signaux acoustiques correspondant sensiblement au contenu identifié comme provenant d'une zone respective de la pluralité de zones acoustiques, et réaliser une reconnaissance vocale automatique sur chacun de la pluralité de seconds signaux acoustiques pour déterminer si le mot de réveil désigné a été prononcé.
