The embodiment of the invention provides a kind of methods of determining upstream voice data, are applied to mobile terminal 10, such as Fig. 1 institute
Show, a main microphon 11 and at least for the voice data for acquiring sound source generation specifically can be set in the mobile terminal 10
One secondary microphone 12, also, the distance of the main microphon 11 apart from sound source is less than distance of the secondary microphone 12 apart from sound source, i.e.,
There is a distance L between main microphon 11 and at least one secondary microphone 12.
In one embodiment, as shown in Figure 1, main microphon 11 involved in the embodiment of the present invention specifically may be disposed at
Mobile terminal 10 one predetermined position of lower part (lower part concretely mobile terminal 10 by when normal use close to user's mouth
That is the part of sound source), at least one secondary microphone 12 is set to the top one opposite with the lower part of mobile terminal 10 and presets position
Set place (top concretely mobile terminal 10 by when normal use close to the part of user's auricle).When secondary microphone 12 exists
When multiple, multiple secondary microphones 12 may be disposed at the predetermined position on 10 top of mobile terminal.
As shown in Fig. 2, the method for the determination upstream voice data can specifically include:
Step 201, the amplitude of the pulse code modulation signal for the first voice data that real-time monitoring main microphon 11 acquires
Whether the first preset value is greater than.
When the acoustic pressure that sound source generates reaches the acoustics overload point (Acoustics Overload Point, AOP) of microphone
When the case where will appear voice data distortion, the amplitude of the pulse code modulation signal of the voice data in such situation can approach
0dBFS.So for the quality for improving upstream voice data, the case where avoiding upstream voice data from being distorted, the present invention is real
Apply the first voice data for determining that the method for upstream voice data needs real-time monitoring main microphon 11 to acquire provided by example
Whether the amplitude of pulse code modulation signal is greater than the first preset value (limit1), and in the first language acquired when main microphon 11
When the amplitude of the pulse code modulation signal of sound data is greater than the first preset value, first voice data is abandoned, by the application institute
The secondary microphone 12 being related to replaces that the appearance is distorted in the second speech data acquired with the first voice data synchronization
One voice data is transmitted as final upstream voice data；If the pulse code modulation of above-mentioned first voice data is believed
Number amplitude be less than or equal to the first preset value, transmitted using first voice data as upstream voice data.

Or close to preset value voice data as second speech data, that is, final transmitted upstream voice data, to can ensure that
The quality of upstream voice data, avoids the occurrence of the case where upstream voice data is distorted.
Second preset value (limit2) also optional, adjustable numerical value involved in above-mentioned, its object is to can
Top-quality one is selected from multiple voice data that multiple secondary microphones 12 acquire, and i.e. there is no the voices of distortion situation
Data.In one embodiment, which is smaller than the first preset value, such as -2dBFS.
Third preset value (limit3) also optional, adjustable numerical value involved in above-mentioned, and by the language of selection
The amplitude of the pulse code modulation signal of sound data be amplified to third preset value process be digital gain amplification process, mesh
The transmission quality for being to ensure that the voice data, that is, enhance the voice data send when signal-to-noise ratio, avoid the voice data
Occur quality problems during transmission.In one embodiment, which can be greater than the first preset value, example
Such as -0.5dBFS.
Step 203, the first voice data of second speech data replacement synchronization is carried out as upstream voice data
Transmission.
It, can be from 12 institute of secondary microphone after passing through the monitoring of above-mentioned voice data, comparison, selecting, determine operation processing
Selection determination can replace the second speech data of the first voice data of synchronization at least one voice data obtained, will
First voice data of second speech data replacement synchronization is transmitted as final upstream voice data, so as to
The quality for ensuring upstream voice data avoids the problem that upstream voice data has distortion.Corresponding to the voice data of conversational class,
Communication effect can be promoted, recipient is enable not hear the voice communication content for sending words side；Corresponding to recording class voice data, can mention
The effect of recording broadcasting is risen, noise is reduced.
The realization that the method for upstream voice data is determined provided by the embodiments of the present invention, by mobile terminal 10
The main microphon 11 and at least one secondary microphone 12 of voice data for acquiring sound source generation, the main microphon 11 are set
There is a distance between at least one secondary microphone 12, and the pulse for monitoring the first voice data of the acquisition of main microphon 11 is compiled
Whether the amplitude of code modulated signal is greater than the first preset value；If the width of the pulse code modulation signal of first voice data of moment
Degree is greater than the first preset value, obtains the second speech data that at least one described secondary microphone 12 acquires at the moment；By institute
The first voice data for stating second speech data replacement synchronization is transmitted as upstream voice data.So as to effectively disappear
Except the distortion situation of upstream voice data, the quality of upstream voice data, use feeling of the enhancing user for mobile terminal are promoted
By.
Below for a specific embodiment of the method for determining upstream voice data provided by the embodiment of the present invention
