Title (EN) DEVICE FOR CAPTURING AND OUTPUTTING AUDIO
(FR) DISPOSITIF DE CAPTURE ET DE SORTIE AUDIO
Abstract:
(EN) This specification describes a device comprising: an acoustically transparent housing; a microphone array comprising a plurality of microphones for capturing audio data, the plurality of microphones being located at a lower end of the housing; at least one speaker configured to output an output sound dependent on an output audio signal, the speaker being located above the microphone array; and a data processing apparatus configured to provide: a plurality of acoustic echo cancellers, each for use in generating a respective echo cancelled audio signal dependent on audio data derived from a respective microphone, using information derived from the said output audio signal; and an adaptive beamformer configured to combine the echo cancelled audio signals..
(FR) La présente invention concerne un dispositif comprenant : un boîtier acoustiquement transparent ; un réseau de microphones comprenant une pluralité de microphones pour capturer des données audio, la pluralité de microphones étant située au niveau d'une extrémité inférieure du boîtier ; au moins un haut-parleur conçu pour émettre un son de sortie en fonction d'un signal audio de sortie, le haut-parleur étant situé au-dessus du réseau de microphones ; et un appareil de traitement de données conçu pour fournir : une pluralité de dispositifs d'élimination d'écho acoustique, chacun destiné à être utilisé pour générer un signal audio à écho éliminé respectif en fonction de données audio dérivées d'un microphone respectif, à l'aide d'informations dérivées dudit signal audio de sortie ; et un formeur de faisceaux adaptatif conçu pour combiner les signaux audio à écho éliminé.
