  • the display module displays voice control information corresponding to the control device of the control device, where the voice control information includes a control state value of the control device, and the control Whether the device is in the user control state, whether the control device performs voice control, and the control device performs voice control content.
  • the display module displays the voice control information of the smart phone on the display screen of the terminal as: the control state value of the smart phone is: 1.
  • the smart phone is in the user control state, the smart phone performs voice control success, the smart phone performs voice control of watching Andy Lau movies, etc.;
  • the voice control information of the display PAD is: the control state value of the PAD is 1, the PAD is not in the user control state, The PAD does not perform voice control or the like.
  • the determining module 20 acquires the audio reflection gain value of each control device. Since the user usually approaches the control device when performing the voice command, the audio reflection gain value is determined. The largest control device is in the user control state, and the determining module 30 determines it as the master device that currently performs voice control on the terminal, thereby further improving the accuracy of the terminal voice control.

Abstract

L'invention concerne un procédé de commande vocale d'un terminal. Ce procédé de commande vocale d'un terminal comprend les étapes suivantes consistant à : détecter le nombre de dispositifs de commande connectés à un terminal (S10) ; lorsqu'il existe plusieurs dispositifs de commande, déterminer un dispositif de commande dans un état d'opération utilisateur parmi les dispositifs de commande (S20) ; déterminer le dispositif de commande dans l'état d'opération utilisateur comme un dispositif de commande maître pour effectuer actuellement une commande vocale sur le terminal (S30) ; et acquérir des données vocales du dispositif de commande maître, et effectuer une opération correspondante conformément aux données vocales (S40) L'invention concerne également un appareil de commande vocale d'un terminal. L'efficacité de la commande vocale du terminal est améliorée.
