Step 102, obtains the second frequency information of the sound simultaneously gathered with described voice signal;
Second frequency information in the embodiment of the present application can be that terminal directly obtains the second frequency information of sound by sensor, namely first frequency information is after collecting sound by microphone, obtain through parsing, and second frequency information is directly obtained by sensor.In intelligent mobile terminal, can an integrated sensor in the terminal, this sensor can directly detect the frequency of external voice, and is recorded by this frequency information.
Second frequency information is the frequency information of the sound directly collected in this application, due to second frequency information record is only frequency, such as, terminal has collected one section of sound by microphone in section sometime, and obtain corresponding first frequency information by resolving, the concrete frequency of which concrete sound can be known by first frequency information.But second frequency information is the frequency information directly gathered by sensor, within the identical time period, by second frequency information, we only know the information of one section of related frequency, corresponding with which concrete sound iff understanding frequency by these second frequency information, we cannot know.
Step 103, according to described first frequency information and second frequency information, sets up the corresponding relation of described second frequency information and described voice signal;
Because second frequency information directly gathers, as in section sometime, terminal had both collected the sound of speaking of people, also the noise in environment has been collected, so first frequency information is exactly the frequency information both having comprised voice, also comprise the frequency information of environmental noise simultaneously, if be only need voice when using the sound in this time period, need the interference getting rid of neighbourhood noise, but in the face of one section of sound cannot simply distinguish voice and neighbourhood noise, within the identical time, the second frequency information of direct collection only comprises the frequency information of sound, but also cannot determine which sound is unwanted by second frequency information.
