Problems solved by technology

[0002] In the environment where the smart home is located, the noise sources are internal noise and external noise. Internal noise includes: air conditioner noise, TV noise, fan noise, etc. External noise includes: car noise, raining sound, etc. For using the microphone- In the singing scene composed of speakers, since the microphone does not have the function of selective audio collection, the noise signal is also collected together with the human voice, and finally the signal output by the speaker also contains the noise signal, and the singing effect is not good
[0003] Most of the existing noise reduction processes use software algorithms for noise reduction processing, but they can only reduce noise for fixed noises, and cannot filter out various environmental noises and machine noises.

Abstract

An embodiment of the present invention provides a microphone noise reduction processing method, including: the microphone collects noise signals; the microphone preprocesses the collected noise signals, and stores the processed noise signals in segments; In the working state, the stored noise signals of each segment are selectively sent to the noise reduction unit. The microphone noise reduction processing method provided by the embodiment of the present invention collects environmental audio data during the period when the speaker is not awakened, and monitors the change of the working state of the speaker, and then selectively sends the collected environmental audio data to the noise reduction unit as a noise reference. source, so that the noise reduction unit can perform noise removal calculations for the subsequent output audio. The microphone noise reduction processing method provided by the present invention can cope with various environmental noise variables, and better realize the filtering of environmental noise and the filtering of the machine's own noise.
