The embodiment of the invention provides a microphone switching method and a terminal, and relates to the technical field of electronic terminals. The problem that the terminal cannot perform normal voice communication when a main microphone in a plurality of microphones is abnormal in the prior art can be solved. The specific scheme is as follows: detecting whether a voice signal input by the main microphone in the plurality of microphones is abnormal, if detecting that the voice signal input by the main microphone is abnormal, setting a secondary microphone as the main microphone so as to perform the voice communication through the set microphone. The embodiment of the invention is used for performing the microphone switching.
