Abstract

L'invention concerne un dispositif intelligent, comprenant un appareil de collecte de voix (103), une puce de réveil (102) et une puce de commande principale (101). L'appareil de collecte de voix (103) est connecté à la puce de réveil (102) pour collecter des premières informations vocales et envoyer les premières informations vocales à la puce de réveil (102) ; la puce de réveil (102) est connectée à la puce de commande principale (101) pour recevoir les premières informations vocales et reconnaître et analyser les premières informations vocales, lorsque les premières informations vocales comprennent une instruction vocale prédéfinie, une notification de réveil est générée, et la notification de réveil est envoyée à la puce de commande principale (101) ; après la réception de la notification de réveil, la puce de commande principale (101) réveille une fonction de commande du dispositif intelligent. En ajoutant une puce de réveil (102) indépendante dans le dispositif intelligent, la puce de commande principale (101) n'a pas besoin d'être toujours en état de fonctionnement pendant un processus de veille, ce qui réduit ainsi la consommation d'énergie du dispositif intelligent. L'invention concerne également un procédé et un appareil de réveil vocal et un support de stockage du dispositif intelligent.
