Abstract

The embodiment of the invention discloses a voice recognition method and device and relates to the field of voice recognition. The problem that the voice recognition rate of TV is low when the TV is subjected to remote voice control by a user is solved. According to the specific scheme, the voice recognition method comprises the following steps: acquiring a first sound source by virtue of a microphone array, separating a target sound source from the first sound source by adopting a preset algorithm, receiving a second sound source transmitted by a peripheral device connected with a voice recognition device, superimposing the target sound source and the second sound source, obtaining the superimposed sound source, recognizing the superimposed sound source, and performing corresponding operations according to the recognition results. The embodiment of the invention is applied to the process of recognizing the user voice by the TV.

Description

technical field [0001] Embodiments of the present invention relate to the field of voice recognition, and in particular, to a voice recognition method and device. Background technique [0002] At present, a microphone array is arranged in a television set, and the array is arranged in a linear or uniform array for far-field voice enhancement, so that a user can control the television set by voice when the user is far away from the television set. [0003] However, when performing far-field speech enhancement, as the sound propagates, as the distance increases, there are many and complex environmental noises and interferences, which will cause the sound pressure level to attenuate, and the ratio of the direct sound to the total of various noises , decreases as the distance between the sound source and the microphone array increases, so if the user is too far away from the TV, the voice recognition rate of the TV is low, and even the recognition system fails completely. In th...
