  • Method and apparatus for improving signal-to-noise ratio of microphone signal
    Patent number: 11798572
    Abstract: Disclosed are a method and apparatus for improving a signal-to-noise ratio of a microphone signal. The method includes: selecting a target microphone to be improved as a first microphone, and selecting a microphone whose signal-to-noise ratio is greater than a signal-to-noise ratio of the first microphone and exceeds a preset first threshold as a second microphone; and adding, by an adder, a voice signal of the first microphone and a voice signal of the second microphone in a case that a same voice signal is inputted, to obtain a first microphone signal whose signal-to-noise ratio has been improved.
    Type: Grant
