Cause, be not repeated here herein.
Step 302, the first voice signal of parsing obtain first object vocal print feature, and the second voice signal of parsing obtains second
Target vocal print feature；
In embodiments of the present invention, voice signal includes caller's voice, music, blown a whistle, and parsing voice signal can
To obtain the vocal print feature of some sound, and first object vocal print feature and the second target sound are determined from some vocal print features
Line feature, wherein, first object vocal print feature and the second target vocal print feature are identical vocal print features, and are all conversed for local terminal
The vocal print feature of person.
Wherein, because being the microphone of mobile terminal and microphone all voice letters in collecting vehicle simultaneously of on-vehicle Bluetooth
Number, so the cycle of the voice signal collected is the same, but amplitude may be different, therefore the first voice signal is parsed
To the frequencies of vocal print feature and the vocal print feature for some sound for parsing to obtain to the second voice signal of some sound be phase
It is corresponding, for example, the vocal print feature for some sound for parsing to obtain to the first voice signal includes first caller's phonetic feature
And first music feature, the vocal print feature for some sound for parsing to obtain to the second voice signal is second caller's phonetic feature
And second musical features, then first caller's phonetic feature is identical with the frequency of second caller's phonetic feature, is same vocal print
Feature, first music feature is identical with the frequency of the second musical features, is also same vocal print feature.
Step 303, determine first amplitude of the sound in the first voice signal belonging to first object vocal print feature, and

Step 305, send to opposite end using the 3rd voice signal as speech signal.
In embodiments of the present invention, calculate the absolute value of the difference of first amplitude and the second amplitude, if absolute value be less than or
Equal to default first threshold, then the amplitude average value of first amplitude and the second amplitude is calculated, will be corresponding with amplitude average value
Voice signal is defined as the 3rd voice signal.
Under normal conditions, the amplitude of the first voice signal and the wheat of on-vehicle Bluetooth that the microphone of mobile terminal collects
The amplitude for the second voice signal that gram wind collects will not differ too big, therefore, sound belonging to first object vocal print feature
Second amplitude of the sound belonging to first amplitude and the second target vocal print feature can not or can not also differ too big, in driving conditions
In, the Mike with the microphone of mobile terminal and on-vehicle Bluetooth may be caused because of the movement of local terminal caller's body position
The distance of wind changes, so as to cause the amplitude and on-vehicle Bluetooth of the first voice signal that the microphone of mobile terminal collects
The amplitude size of the second voice signal that collects of microphone it is unstable, then of the sound belonging to first object vocal print feature
The amplitude size of second amplitude of the sound belonging to one amplitude and the second target vocal print feature is also unstable, if by first amplitude with
Voice signal corresponding to the larger amplitude of numerical value is defined as the 3rd voice signal in second amplitude, then the 3rd voice may be caused to believe
Number amplitude it is also unstable, for example, first threshold is 10db, the first amplitude in current duration is 42db, and the second amplitude is
36db, the first amplitude in next duration are 34db, and the second amplitude is 36db, first amplitude and the second amplitude in current duration
Absolute value be less than first threshold, in next duration first amplitude with the absolute value of the second amplitude again smaller than first threshold, if will
First amplitude voice signal corresponding with the amplitude that numerical value in the second amplitude is larger is defined as the 3rd voice signal, then when current
It is that voice signal corresponding to 42db is defined as the 3rd voice letter to need the microphone of mobile terminal collecting first amplitude in length
Number, it is that voice signal corresponding to 36db is defined as to need the microphone of on-vehicle Bluetooth collecting the second amplitude in next duration
3rd voice signal, 36db is gone to from 42db, the down conversion of amplitude one of the 3rd voice signal 6db is right if frequently changing
It is small when big when holding the voice messaging received also, the speech quality of opposite end can be influenceed.Therefore, will voice corresponding with amplitude average value
Signal is defined as the 3rd voice signal, i.e., voice signal corresponding with (36+42)/2=39db is defined as into current duration
Three voice signals, the interior voice signal corresponding with (36+34)/2=35db of next duration is defined as the 3rd voice signal, when current
The long amplitude change rate with next duration is 4db so that the amplitude of the 3rd voice signal changes more gentle, by the 3rd language
Sound signal is sent to opposite end as speech signal, it can be ensured that the speech quality of opposite end.
If absolute value is more than first threshold, the first amplitude amplitude larger with numerical value in the second amplitude is determined, and will be with number
Voice signal corresponding to being worth larger amplitude is defined as the 3rd voice signal.
In embodiments of the present invention, if absolute value is more than first threshold, then it represents that the difference of first amplitude and the second amplitude
It is excessive, if calculating the amplitude average value of first amplitude and the second amplitude again, the amplitude average value can be caused too small, amplitude is put down
Voice signal corresponding to average is defined as the 3rd voice signal and is sent to opposite end, can influence the speech quality of opposite end, for example, the
One threshold value is 10db, and the first amplitude in current duration is 42db, and the second amplitude is 10db, then amplitude average value be (42+10)/
2=26db, it is that voice signal corresponding to 26db is defined as the 3rd voice signal by amplitude, and using the 3rd voice signal as call
The amplitude that signal sends to opposite end the speech signal for because the amplitude is too small, causing opposite end to receive is also too small, reduces speech quality.
It should be noted that if absolute value is more than first threshold, also to compare the larger amplitude of numerical value and default second
The size of threshold value, more than Second Threshold, then it represents that amplitude is excessive, can cause unsweet sound phenomenon, and the excessive speech signal of amplitude is passed
To opposite end, opposite end can hear distorsion, influence speech quality, therefore, if the larger amplitude of numerical value is less than or equal to Second Threshold,
Voice signal corresponding with the amplitude that numerical value is larger is defined as the 3rd voice signal, and believed the 3rd voice signal as call
Number send to opposite end；If the larger amplitude of numerical value is more than Second Threshold, need to carry out range of decrease processing to the amplitude of voice signal,
The voice signal refers to voice signal corresponding to the larger amplitude of numerical value, based on default 3rd threshold value, by the voice signal
Range-adjusting be the 3rd threshold value, and be defined as the 3rd voice signal by the voice signal after amplitude is adjusted, and by the 3rd voice
Signal is sent to opposite end as speech signal, so as to ensure that the speech signal that opposite end receives is not distorsion, improves call
Quality.
