Title
(EN) AUDIO PROCESSING IN A LOW-BANDWIDTH NETWORKED SYSTEM
(FR) TRAITEMENT AUDIO DANS UN SYSTÈME EN RÉSEAU À FAIBLE BANDE PASSANTE
Abstract
(EN)
The present disclosure is generally directed a system to detect activation phrases within input audio signals transmitted over a low-bandwidth network. The system can use a two-stage activation phrase detection process. First a sensing device, which can include a plurality of microphones for detecting an input audio signal, can detect an input audio signal that includes a candidate activation phrase. Second, the sensing device can transmit the recordings of the input audio signal to a client device for confirmation that the input audio signal includes the activation phrase.

La présente invention concerne de manière générale un système destiné à détecter des expressions d'activation dans des signaux audio d'entrée transmis sur un réseau à faible bande passante. Le système peut utiliser un processus de détection d'expression d'activation en deux étapes. Tout d'abord, un dispositif de détection pouvant comprendre une pluralité de microphones pour détecter un signal audio d'entrée peut détecter un signal audio d'entrée incluant une expression d'activation candidate. Ensuite, le dispositif de détection peut transmettre les enregistrements du signal audio d'entrée à un dispositif client pour confirmer que ledit signal inclut l'expression d'activation.
