Abstract

The invention discloses a smart home voice control system combined with a video channel and a control method thereof. The system comprises a gesture detection module, a human face detection module, a recognition system module, a command judgment module and a command display and confirmation module which are sequentially connected. The recognition system module comprises a lip language part and a voice part, wherein the lip language part comprises a human face tracking and positioning module, a lip language video input module and a lip language recognition module which are sequentially connected; and the voice part comprises a voice input module and a voice recognition module which are sequentially connected. By detecting control gestures and recognizing human faces and lip language information to supplement the recognized voice information, the accuracy of control commands is improved and the feasibility of using voices to control a smart home is increased. The smart home voice control system combined with the video channel has very strong interference resistance, can be widely used for various complex environment modes and is particularly suitable for the situation of high noise because of a great number of people in home environments.

Description

technical field [0001] The invention relates to a video voice recognition technology, in particular to a smart home voice control system combined with a video channel and a control method thereof. Background technique [0002] At present, most of the complicated home appliances are remote controlled through the keyboard input mode of the remote control. remote control. Language is the most direct and convenient way of communication and expression for human beings. If speech recognition technology is adopted, the original passive static structure can be transformed into a smart tool with active recognition of speech execution, so as to meet the growing needs of people. [0003] In recent years, speech recognition technology has developed very rapidly, and many automatic speech recognition products have appeared, such as the ViaVoice speech system developed by IBM. However, these systems still lack strong anti-interference ability, because it can only obtain information from...
