The invention discloses an intelligent TV speech enhancement control method and system based on multi-microphone noise reduction. The method comprises the following steps: collecting main audio information and auxiliary audio information of the intelligent TV surrounding environment in real time through a main microphone and various auxiliary microphones; performing similarity matching on the output audio information output by an intelligent TV by utilizing the collected main audio information and the auxiliary audio information, thereby acquiring a similarity matching result; judging whetherinput control audio information is existent in the collected main audio information and the auxiliary audio information based on the similarity matching result; performing filtering frequency divisionprocessing on the main audio information and the auxiliary audio information to extract the main frequency division information and the auxiliary frequency division information; performing enhanced fusion processing on the main frequency division information and the auxiliary frequency division information; and inputting the enhanced fusion audio information into an intelligent TV audio control module. In the control method disclosed by the embodiment of the invention, the speech input control of the TV in the program playing process can be realized, the speech control accuracy is improved, and the user experience is enhanced.
Description
technical field [0001] The invention relates to the technical field of intelligent control, in particular to a method and system for intelligent TV voice enhancement control based on multi-microphone noise reduction. Background technique [0002] Smart TV, based on Internet application technology, has an open operating system and chip, has an open application platform, can realize two-way human-computer interaction function, integrates multiple functions such as audio-visual, entertainment, data, etc. TV products with individual needs; its purpose is to bring users a more convenient experience, which has become the trend of TV.
