Embodiments provide a kind of method determining upstream voice data, be applied to mobile terminal 10, as Fig. 1 institute
Show, in this mobile terminal 10, specifically can be provided with the main microphon 11 and at least of the speech data for gathering sound source generation
One secondary microphone 12, and, this main microphon 11 is less than the distance apart from sound source for the secondary microphone 12 apart from the distance of sound source, that is,
Have one apart from L between main microphon 11 and at least one secondary microphone 12.
In one embodiment, as shown in figure 1, the main microphon 11 involved by the embodiment of the present invention specifically may be disposed at
Bottom one predetermined position of mobile terminal 10 is (near user's mouth when concretely mobile terminal 10 is normally used for this bottom
The i.e. part of sound source), at least one secondary microphone 12 is arranged at mobile terminal 10 top relative with described bottom one and presets position
Place's of putting (near the part of user's auricle when concretely mobile terminal 10 is normally used on this top).When secondary microphone 12 exists
When multiple, multiple secondary microphones 12 may be disposed at the predetermined position on mobile terminal 10 top.
As shown in Fig. 2 this determines that the method for upstream voice data specifically can include：
Step 201, the amplitude of the pulse code modulation signal of the first speech data of real-time monitoring main microphon 11 collection
Whether it is more than the first preset value.
When the acoustic pressure that sound source produces reaches the acoustics overload point (Acoustics Overload Point, AOP) of mike
When the situation of speech data distortion occur, so in the case of the amplitude of the pulse code modulation signal of speech data can be close
0dBFS.So in order to improve the quality of upstream voice data, it is to avoid the situation of distortion in upstream voice data, the present invention is real
The method applying determination upstream voice data that example is provided needs the first speech data of real-time monitoring main microphon 11 collection
Whether the amplitude of pulse code modulation signal is more than the first preset value (limit1), and in the first language gathering when main microphon 11
When the amplitude of the pulse code modulation signal of sound data is more than the first preset value, abandon this first speech data, by the application institute
The secondary microphone 12 being related to replace that this distortion in the second speech data with the first speech data synchronization collection the
One speech data is transmitted as final upstream voice data；If the pulse code modulation letter of above-mentioned first speech data
Number amplitude be less than or equal to the first preset value, this first speech data is transmitted as upstream voice data.
As described above, when speech data pulse code modulation signal amplitude can close to 0dBFS when speech data can go out
, therefore, the situation of distortion, involved by the embodiment of the present invention in order to avoid upstream voice data in the situation of existing distortion

According to.
The realization of above-mentioned steps, can multiple secondary microphones 12 collection multiple speech datas in selection signal optimal quality
Or the speech data close to preset value is final transmitted upstream voice data as second speech data, thus can ensure that
The quality of upstream voice data, it is to avoid the situation that distortion in upstream voice data occurs.
Above-mentioned involved the second preset value (limit2) also optional, adjustable numerical value, its object is to can
Select top-quality one voice that there is not distortion situation from multiple speech datas of multiple secondary microphones 12 collection
Data.In one embodiment, this second preset value is smaller than the first preset value, such as -2dBFS.
Above-mentioned involved the 3rd preset value (limit3) also optional, adjustable numerical value, and the language that will select
The process that the amplitude of the pulse code modulation signal of sound data is amplified to the 3rd preset value is the process that digital gain amplifies, mesh
The transmission quality being to ensure that this speech data, that is, strengthen this speech data send when signal to noise ratio, it is to avoid this speech data
During transmission, quality problems occur.In one embodiment, the 3rd preset value can be more than the first preset value, example
As -0.5dBFS.
Step 203, the first speech data that second speech data is replaced synchronization is carried out as upstream voice data
Transmission.
Through above-mentioned speech data monitoring, contrast, select, determine operation process after, can be from secondary microphone 12 institute
Select at least one speech data obtaining to determine the second speech data that can replace synchronization first speech data, will
The first speech data that this second speech data replaces synchronization is transmitted as final upstream voice data, thus can
Guarantee the quality of upstream voice data, it is to avoid upstream voice data has distortion.Corresponding to the speech data of conversational class,
Communication effect can be lifted, enable recipient not hear the voice call content sending words side；Corresponding to recording class speech data, can carry
Rise the effect of recording broadcasting, reduce noise.
The realization of the method for determination upstream voice data that the embodiments of the present invention are provided, by mobile terminal 10
It is provided for gathering a main microphon 11 of the speech data that sound source produces and at least one secondary microphone 12, this main microphon 11
There is and at least one secondary microphone 12 between a distance, and monitor the pulse of the first speech data of main microphon 11 collection and compile
Whether the amplitude of code modulated signal is more than the first preset value；If the width of the pulse code modulation signal of moment first speech data
Degree is more than the first preset value, obtains the second speech data that at least one secondary microphone 12 described gathers in the described moment；By institute
The first speech data stating second speech data replacement synchronization is transmitted as upstream voice data.Thus can effectively disappear
Except the distortion situation of upstream voice data, lift the quality of upstream voice data, strengthen the use feeling for mobile terminal for the user
It is subject to.
One specific embodiment of the method for the determination upstream voice data being provided below for the embodiment of the present invention
