The application scenarios of the embodiment of the present invention may is that as shown in Fig. 1 (a), there is main microphon A in smart phone bottom end and raises
There is secondary microphone C on sound device B, the top of smart phone.Under normal conditions, main microphon A is mainly used to acquire the voice of user, secondary
Microphone C is mainly used to acquire outside noise.Smart phone removes main microphon by the outside noise that secondary microphone C is acquired
Noise in the user speech of A acquisition, to generate the higher voice signal of voice quality.
But when user hold smart phone and smart phone is placed on make a phone call by ear when, the finger of user is sometimes
The main microphon A that smart phone bottom end can be blocked, the voice of normal acquisition user is unable to so as to cause main microphon A.At this point, intelligence
Can mobile phone triggering with the voice of user is acquired in the loudspeaker B of smart phone bottom end, to improve voice call quality.
It should be noted that not limiting the position of main microphon A, loudspeaker B and secondary microphone C in Fig. 1 (a).
The embodiment of the invention discloses a kind of voice communication method and mobile terminals, can be improved voice call quality.With
It is lower to be described in detail respectively.
Referring to Figure 1, Fig. 1 is a kind of flow diagram of voice communication method disclosed by the embodiments of the present invention.Such as Fig. 1 institute
Show, which may comprise steps of.
S101, mobile terminal detect the quality of the first voice signal, wherein first voice signal is to pass through mobile terminal
The voice signal of the microphone acquisition of configuration, and first voice signal is to upload to base station by uplink channel.
The mobile terminal may include with voice call function, operation Android operation system, iOS operating system,
Mobile device of Windows operating system or other operating systems, such as mobile phone, removable computer, tablet computer etc..Together
When, which can match microphone and loudspeaker.
The mobile terminal can detect the quality of first voice signal by the objective parameter of first voice signal,
Wherein, the objective parameter of first voice signal can be the signal-to-noise ratio (Signal-to-Noise of first voice signal
Ratio, SNR).SNR can refer to the ratio between the mean power of clean speech signal whithin a period of time and noise signal.
Optionally, the embodiment of the present invention can be applied to the smart phone as shown in Fig. 1 (a).The smart phone includes master
Microphone A and secondary microphone C；Main microphon A is mainly used to acquire the voice of user, and it is extraneous that secondary microphone C is mainly used to acquisition
Noise, smart phone remove the noise in the user speech that main microphon A is acquired by the outside noise that secondary microphone C is acquired
To obtain clean speech signal；The smart phone is acquired outer by the clean speech signal and secondary microphone C that calculate acquisition
The ratio between the mean power of boundary's noise, can be obtained SNR.
The uplink channel can refer to that the physical channel of the mobile terminal Yu the base station communication, the i.e. mobile terminal will be adopted
The signal collected uploads to the communication physical channel of the base station.
S102, the mobile terminal judge whether the quality of first voice signal is less than default quality of speech signal threshold value,
If judging, the quality of first voice signal is less than the default quality of speech signal threshold value, S103 is thened follow the steps, conversely, then tying
This process of beam.
Optionally, if the quality of first voice signal is assessed with SNR, S102 can be with are as follows: the mobile terminal is sentenced
Whether the SNR of first voice signal of breaking is less than default SNR.If the SNR of first voice signal is less than default SNR, judge
The quality of first voice signal is less than the default quality of speech signal threshold value；Conversely, if the SNR of first voice signal is greater than
Or be equal to default SNR, then judge that the quality of first voice signal is greater than or equal to the default quality of speech signal threshold value.Its
In, the SNR of first voice signal can be indicated with 0.7 or 0.8 equal numerical value, which can wait numerical value with 0.4 or 0.5
It indicates.
The loudspeaker that S103, the mobile terminal trigger the mobile terminal configuration acquires the second voice signal.
Optionally, mobile terminal can configure loudspeaker, and the loudspeaker may include vibrating diaphragm and magnetic induction loop.Step
S102 specific steps can be with are as follows:
Step 11), the mobile terminal acquire second voice signal by the vibrating diaphragm and the magnetic induction loop.
