Abstract:
The present invention discloses a method and an apparatus for reducing noise in voices of a mobile terminal and relates to the field of communications technologies, which can improve the effect of noise reduction. The method includes: selecting, from a voice headphone and a microphone built in the mobile terminal, a current communicating microphone and a current noise reducing microphone; obtaining an audio signal received by the current communicating microphone and an audio signal received by the current noise reducing microphone; performing noise reduction according to the audio signal received by the current communicating microphone and the audio signal received by the current noise reducing microphone, so as to obtain a noise reduced signal; and performing voice coding according to the noise reduced signal to generate an audio output signal.
