Title (EN) MULTI-MODE NOISE CANCELLATION FOR VOICE DETECTION
(FR) ANNULATION DE BRUIT À MODES MULTIPLES POUR DÉTECTION VOCALE
Abstract:
(EN) Methods and systems provide dynamic selection of noise-cancelling algorithms, and dynamic activation and deactivation of microphones to provide multi-mode noise cancellation for a voice-detecting headset in situations where ambient noise prevents voice navigation from accurately interpreting voice commands. To do so, when an ambient noise is detected that exceeds a threshold, a particular noise-cancelling algorithm best-suited for the situation is selected, and one or more noise-detecting microphones is activated. The noise-detecting microphone(s) receiving the highest level of ambient noise can remain activated while the remaining noise-detecting microphones can be deactivated. A speech signal received by the speech microphone can then be optimized by cancelling the ambient noise signal received from the activated noise-detecting microphone(s) using the selected noise-cancelling algorithm. After the speech signal is optimized, it can be communicated to the voice-detecting headset for interpretation.
(FR) La présente invention concerne des procédés et des systèmes qui assurent une sélection dynamique d'algorithmes d'annulation de bruit, et une activation et une désactivation dynamiques de microphones afin d'obtenir une annulation de bruit à modes multiples pour un casque de détection vocale dans des situations où le bruit ambiant empêche une navigation vocale d'interpréter correctement des instructions vocales. Pour ce faire, lorsqu'un bruit ambiant qui dépasse un seuil est détecté, un algorithme d'annulation de bruit spécifique, qui est le mieux adapté à la situation, est sélectionné, et un ou plusieurs microphones de détection de bruit sont activés. Lesdits microphones de détection de bruit recevant le niveau de bruit ambiant le plus élevé peuvent rester activés pendant que les autres microphones de détection de bruit peuvent être désactivés. Un signal vocal reçu par le microphone vocal peut ensuite être optimisé par annulation du signal de bruit ambiant reçu desdits microphones de détection de bruit activés à l'aide de l'algorithme d'annulation de bruit sélectionné. Une fois optimisé, le signal vocal peut être communiqué au casque de détection vocale en vue de son interprétation.
