Abstract

The invention discloses a microphone-based voice detection method and device. The method comprises the following steps of acquiring a first digital voice signal and a second digital voice signal, wherein the first digital voice signal is obtained by processing a first analog voice signal acquired by a first microphone, and the second digital voice information is obtained by processing a second analog voice signal acquired by a second microphone; analyzing the second digital voice signal to obtain a second background voice signal in the second digital voice signal; and obtaining an effective voice signal corresponding to a voice signal sent by a wire controller based on the first digital voice signal and the second background voice signal. According to the method and the device, the technical problem that the detection accuracy is relatively low due to the fact that the noise exists in a detection environment when the wire controller is subjected to voice detection in the related technology is solved.

Description

technical field [0001] The present invention relates to the technical field of voice processing, in particular to a microphone-based voice detection method and device. Background technique [0002] In view of the misdetection of the voice of the wire controller by the intelligent detection equipment of the wire controller, after on-site investigation, it was found that the voice detection principle of the wire controller is a detection method for the microphone to receive a voice signal with a fixed frequency spectrum. However, because there is a lot of noise in the on-site use environment, the voice of the wire controller will be very weak, making it difficult to measure or even make a wrong measurement, which will affect the efficiency of intelligent detection of the wire controller. [0003] Aiming at the problem of low detection accuracy caused by noise in the detection environment when performing voice detection on the wire controller in the above-mentioned related tech...
