Multimedia Device Voice Control System and Method, and Computer Storage Medium

摘要

A voice control system and method for a multimedia device are provided. The system includes an image sensing module configured to collect a user action image; an image recognizing module configured to determine a type or a status of a control instruction according to the user action image; a voice recognition status managing module configured to activate or wake up the voice recognition program according to a type of a current control instruction; a pickup module configured to collect voice signal; a voice recognizing module configured to recognize the collected voice data to generate a control instruction; and a multimedia function module configured to execute the control instruction to provide a corresponding multimedia function to the user. An image recognition technology, a voice recognition technology, and a storage medium of a computer are combined in the illustrated embodiment, a free and convenient voice control which is not depended on a hand-held remote control unit and not limited to a close pickup device is achieved. The interference of the sound output by the multimedia device, the environment background noise, and a non-control instruction voice signal of the user to the control instruction voice recognition can be effectively avoided, the instruction of the user can be precisely recognized.
