The embodiment of the present invention provides a kind of Mike's changing method, and for many Mikes terminal, these many Mikes wrap
Including a main Mike and at least one secondary Mike, see Fig. 2, key step may include that
201, terminal detects the voice signal of main Mike input the most extremely.
Wherein, terminal can be believed by detection voice of main Mike input before coder Codec
Number whether abnormal, the voice signal of the main Mike input after can being processed by detection coder Codec
Whether abnormal, or whether the voice signal after can being processed by detection digital signal processor DSP
Abnormal, determine that the voice signal that main Mike inputs is the most abnormal.Certainly, terminal can also be by detection
The voltage of the voice signal of main Mike input, or detect the frequency spectrum of the voice signal of main Mike input, or
Person, by the way of speech recognition, determines that the voice signal that main Mike inputs is the most abnormal.The present invention is real
Execute example the most abnormal to which kind of mode to detect and to determine the voice signal that main Mike inputs especially by
Do not limit.
If 202 terminals detect that the voice signal that main Mike inputs is abnormal, then terminal is by a secondary wheat
Gram it is set to main Mike, in order to carry out voice by the main Mike after arranging and send words.
Wherein, when terminal detects the voice signal exception the most main Mike exception that main Mike inputs,
The main Mike specified may damage, it is impossible to carries out voice again and send words, now can be secondary by one
Mike is set to main Mike, in order to carries out voice by the main Mike after arranging and send words, thus
Ensure that terminal can be normally carried out voice call.
Need to carry out additionally, Mike's changing method that the embodiment of the present invention provides is also applied for terminal
Scene during recording.Concrete, when terminal is recorded, main wheat in many Mikes can be detected
Whether the voice signal of gram input is abnormal, if terminal detects that the voice signal that main Mike inputs is different
Often, then a secondary Mike is set to main Mike by terminal, in order to entered by the main Mike after arranging
Row recording, during such that it is able to main Mike occurs abnormal in many Mikes of solution prior art, terminal can not
The problem being normally carried out recording.From carry out unlike voice call, recorded by main Mike
During sound, secondary Mike can not work, and digital signal processor DSP is also without the signal to typing
Carry out noise reduction process, say, that if terminal detects that the voice signal that main Mike inputs is abnormal,
Then terminal Mike of can leaving unused is set to main Mike, in order to by the main Mike after arranging
Record.
The embodiment of the present invention provides a kind of Mike's changing method, when main Mike input in many Mikes being detected
Voice signal exception time, a secondary Mike is set to main Mike, in order to after arranging
New main Mike carries out voice and send words, with prior art in when the main Mike specified occurs abnormal,
Other secondary Mike in terminal can not carry out voice and send words to compare, the side that the embodiment of the present invention provides
Method can solve the problem that when main Mike occurs abnormal in many Mikes of prior art, terminal can not be normally carried out voice
The problem of call.
The embodiment of the present invention provides a kind of Mike's changing method, for many Mikes terminal, this terminal
Including Mike's routing switch, and the input of Mike's routing switch is connected with many Mikes, Mai Kelu
It is connected by the input of the outfan switched with coder Codec, sees Fig. 3, the most permissible
Comprise the following steps:
301, the voltage of the voice signal that terminal detects main Mike input by Mike's routing switch is
No exception.
In this step, the voice signal that terminal inputs main Mike through coder Codec it
Before, can be the most different by the voltage of the voice signal of Mike's routing switch detection main Mike input
Often.
Exemplary, comparator can be set in Mike's routing switch, detect main Mike input
The voltage of voice signal whether abnormal.Concrete, when causing due to reasons such as main Mike's damages
During main Mike's exception, main Mike cannot typing voice signal, the main Mike now detected input
Signal be probably the noise of circuit, owing to the amplitude of circuit noise is the least e.g., less than
10mV, it is believed that main Mike is without input signal, and the voice signal of the most main Mike input is abnormal,
Otherwise, when main Mike is normal, the voice signal of typing should be that the voice signal of user is made an uproar with environment
The superposition of sound.Therefore, it is possible to one end of comparator to be set to the constant voltage of 10mV, will
The voice signal that the other end inputs with main Mike is connected, if the language of main Mike input in the appointment time
The voltage magnitude of tone signal is less than 10mV, then it is believed that main Mike's no signal inputs, and main Mike
The electric voltage exception of the voice signal of input.Exemplary, this appointment time can be 1 minute.
Simultaneously as the voltage magnitude of environment noise is generally higher than 10mV, thus can also pass through
Comparator in Mike's routing switch comes whether the voice signal of comparison secondary Mike input is less than
10mV, if the voltage magnitude of environment noise is less than 10mV in secondary Mike, then it is believed that secondary wheat
The input of gram no signal, the electric voltage exception of the voice signal of secondary Mike input, i.e. this secondary Mike are abnormal
Cisco unity malfunction.
In addition it is also possible to design Mike's routing switch by other hardware circuit, thus detect
The voltage of the voice signal of main Mike input is the most abnormal, and the embodiment of the present invention does not limits.
It should be noted that the voice that main Mike can be inputted by terminal when conversing every time
Signal carries out one-time detection；Abnormal in order to prevent main Mike from occurring in communication process, terminal is also
The voice signal that periodically can input main Mike detects, such as can be every 10 points
Clock detects once, does not limits.
If 302 electric voltage exceptions, then terminal determines that the voice signal that main Mike inputs is abnormal.
If in step 301, Mike's routing switch detects the electricity of the voice signal that main Mike inputs
Pressure is abnormal, then may determine that the voice signal that main Mike inputs is abnormal, may thereby determine that main wheat
Gram exception.
It should be noted that the voice signal that terminal can also input main Mike is through coder
Arranging processing unit before Codec, the voice signal inputting main Mike carries out spectrum analysis, if
Frequency spectrum not (the such as language in user voice signal spectral range of the voice signal of main Mike input
Sound spectrum scope is generally 80Hz～12kHz), then may determine that the voice signal that main Mike inputs
Abnormal；Or this processing unit can also determine by the way of speech recognition that main Mike inputs
Voice signal whether abnormal.The embodiment of the present invention language to specifically how detecting main Mike input
Tone signal is the most abnormal not to be limited.
303, terminal passes through Mike's routing switch output port by main Mike abnormal for voice signal
Disconnect with input port corresponding with main Mike in coder Codec, and according to default
The selected secondary Mike of Mike's order, by the output port of selected secondary Mike and coder Codec
The input port corresponding with main Mike connects.
When in step 302, terminal determines that the voice signal that main Mike inputs is abnormal, and the most main Mike is different
Chang Shi, main Mike may damage, it is impossible to carries out voice again and send words.Now, terminal is permissible
By Mike's routing switch by the output port of main Mike abnormal for voice signal and coder
Input port corresponding with main Mike in Codec disconnects, and according to default Mike's order choosing
Fixed secondary Mike, by the output port of selected secondary Mike and coder Codec with main Mike couple
The input port answered connects, thus arranges new main Mike.Wherein, Mike's routing switch is arranged
The process schematic of new main Mike may refer to Fig. 4.By the output port of selected secondary Mike
After connecting with input port corresponding with main Mike in coder Codec, this secondary Mike is set
It is main Mike, now can carry out voice by the new main Mike after arranging and send words, thus protect
Card user can be normally carried out voice call.
During according to the default selected secondary Mike of Mike's order, if step 301 detects
During to the i.e. secondary Mike exception of electric voltage exception of the voice signal of secondary Mike input to be selected,
Then can come the secondary wheat after current secondary Mike according in the default selected order of Mike's order
Gram, and it is set to new main Mike.
Exemplary, terminal can be according to many Mikes position in mobile phone and the use habit etc. of user
Information, is configured default Mike's order, and default Mike is sequentially written in memorizer.
Such as, if mobile phone has 3 Mikes of numbered 1,2,3, lay respectively at bottom front, just
In the middle part of top, face and the back side, then No. 1, No. 2, No. 3 Mikes combination can be set, and according to
The use habit of user, the Mike's order that can the main Mike preferentially used order be i.e. preset sets
Be set to No. 1, No. 2, No. 3 Mikes, i.e. No. 1 Mike as the priority of main Mike higher than No. 2
Mike, No. 2 Mikes as the priority of main Mike higher than No. 3 Mikes.When conversing, can
Using by No. 1 Mike as main Mike, No. 2 Mikes, No. 3 Mikes are as secondary Mike；When No. 1 wheat
Time gram abnormal, according to default Mike's order, No. 2 Mikes can be set to main Mike, No. 3 wheats
Gram as secondary Mike, when No. 1 Mike recovers normal, can recover be set to by No. 1 Mike
Main Mike, No. 2 Mikes, No. 3 Mikes are secondary Mike；When No. 1 Mike, No. 2 Mikes are the most abnormal
Time, No. 3 Mikes can be set to main Mike, now, due to 1 according to default Mike's order
Number Mike, No. 2 Mikes are all abnormal, thus terminal only includes main Mike and do not includes secondary Mike, terminal
Carry out voice by main Mike and send words, but voice de-noising can not be carried out by secondary Mike.Certainly,
Can also by No. 1, No. 2, Mike's order in No. 3 Mikes combination be set to No. 2, No. 1,3
Number or No. 3, No. 2, No. 1 etc..
If additionally, mobile phone includes 3 Mikes, it is also possible to arrange No. 1, No. 2 Mike's combinations, or
No. 1, No. 3 Mike's combinations or No. 1 Mike's combination etc., now, not included in the Mike's group arranged
Some or certain several Mikes in conjunction will not work, and be idle Mike.The embodiment of the present invention
The concrete Mike arranged combination and the Mike's order preset are not limited.
It addition, when proceeding by voice call, currently used main Mike can be Mike's group
Close the Mike that medium priority is the highest, it is also possible to the main Mike arranged when being last call.
It should be noted that the embodiment of the present invention is to set between Mike and coder Codec
Putting what Mike's routing switch illustrated, this Mike's routing switch can also be integrated in coder
Inside Codec, the embodiment of the present invention does not limits.
Certainly, Mike's changing method that the embodiment of the present invention provides is also applied for terminal to be needed to carry out
Scene during recording.Concrete, when terminal is recorded, Mike's routing switch can be passed through
The voltage of the voice signal detecting main Mike input is the most abnormal, if electric voltage exception, then terminal is true
The voice signal of fixed main Mike input is abnormal, and now, terminal passes through Mike's routing switch by voice
Defeated corresponding with main Mike with in coder Codec of the output port of the main Mike of abnormal signal
Inbound port disconnects, and according to the default selected secondary Mike of Mike's order, by selected secondary wheat
Gram the output port input port corresponding with main Mike with in coder Codec connect, thus
When can solve that in many Mikes of prior art, main Mike occurs abnormal, terminal can not be normally carried out recording
Problem.From carry out unlike voice call, when being recorded by main Mike, secondary Mike can
Not work, digital signal processor DSP carries out noise reduction process also without to the signal of typing,
If it is to say, terminal detects that the voice signal that main Mike inputs is abnormal, then terminal can be by
One Mike of leaving unused is set to main Mike, in order to recorded by the main Mike after arranging.
The embodiment of the present invention provides a kind of Mike's changing method, when by many Mikes and coder
Mike's routing switch between Codec, detects that in many Mikes, the voice signal of main Mike input is different
Chang Shi, by the output port of main Mike abnormal for voice signal and coder Codec with main wheat
Gram corresponding input port disconnects, then according to the default selected secondary Mike of Mike's order,
The input corresponding with main Mike with in coder Codec by the output port of selected secondary Mike
Port connects, thus this secondary Mike is set to new main Mike, now can be by arranging after
Main Mike carry out voice and send words, it is thus possible to solve main Mike in many Mikes of prior art and occur
Time abnormal, the problem that terminal can not be normally carried out voice call.
The embodiment of the present invention provides a kind of Mike's changing method, sees Fig. 5, mainly can include with
Lower step:
501, terminal detects the voice signal of main Mike input by digital signal processor DSP
Voltage is the most abnormal.
In this step, the voice signal that terminal inputs main Mike through coder Codec it
After, the voltage of the voice signal of main Mike input can be detected by digital signal processor DSP
The most abnormal.Due to after coder Codec, the analog voice signal of Mike's input
Have been converted to digital signal.When causing main Mike's exception due to reasons such as main Mike's damages,
Main Mike cannot typing voice signal, now, the main Mike detected before coder Codec
Input signal is probably the noise of circuit.Exemplary, due to the noise signal voltage amplitude of circuit
Be worth less, after coder Codec is converted into digital signal for constant low level (if warp
Anti-phase process is likely to as constant high level), thus it is believed that main Mike is without input signal,
The voice signal of the most main Mike input is abnormal.When main Mike is normal, the voice signal of typing should
This is the voice signal of user and superposing of environment noise, through coder Codec analog digital conversion
After signal should be low and high level interval digital signal.Therefore, it is possible to pass through digital signal
Whether the voltage of the voice signal that processor DSP detects main Mike input is constant voltage, if
It is to may determine that the voice signal electric voltage exception that main Mike inputs.In like manner, abnormal as secondary Mike
Time, it is also possible to the voltage causing the voice signal that secondary Mike inputs is steady state value, thus, it is possible to
The most abnormal to be detected the voltage of the voice signal of secondary Mike input by the method.
It is of course also possible to detected the voltage of the voice signal of main Mike input by other method
The most abnormal, such as by detecting whether the voltage of the voice signal of main Mike input exceedes a certain
Threshold value, exceedes this appointment threshold value if being in the appointment time, then it is believed that main Mike input
The electric voltage exception of voice signal, which kind of mode of employing is detected main Mike input by the embodiment of the present invention
The voltage of voice signal whether abnormal do not limit.
It should be noted that the voice signal that when conversing every time, main Mike can be inputted
Carry out one-time detection, it is also possible to the voice signal periodically inputted main Mike detects,
Such as can every detection in 10 minutes once not limit.
If 502 electric voltage exceptions, then terminal determines that the input signal of main Mike is abnormal.
If in step 501, digital signal processor DSP detects the voice letter that main Mike inputs
Number electric voltage exception, then may determine that the voice signal that main Mike inputs is abnormal, such that it is able to really
Fixed main Mike is abnormal.
It should be noted that the voice that main Mike can also be inputted by digital signal processor DSP
Signal carries out spectrum analysis, if the frequency spectrum of the voice signal of main Mike input is not believed at user speech
In number spectral range (such as voice spectrum scope is generally 80Hz～12kHz), then may determine that
Main Mike's input signal is abnormal, so that it is determined that main Mike is the most abnormal.The embodiment of the present invention is to tool
How body detects the voice signal of main Mike input does not limits the most extremely.
503, terminal selectes secondary wheat by digital signal processor DSP according to default Mike's order
Gram, and then control selected secondary Mike and carry out voice as main Mike by coder Codec
Send words.
When in step 502, terminal determines that the voice signal that main Mike inputs is abnormal, and the most main Mike is different
Chang Shi, main Mike may damage, it is impossible to carries out voice again and send words.At this point it is possible to pass through
Digital signal processor DSP is according to the default selected secondary Mike of Mike's order, and then controls selected
Secondary Mike carry out voice as main Mike by coder Codec and send words.Concrete, numeral
Signal processor DSP can be by main Mike couple abnormal with voice signal in coder Codec
The output port answered is corresponding with main Mike abnormal with voice signal in digital signal processor DSP
Input port disconnect, and according to the default selected secondary Mike of Mike's order, by coder
In output port corresponding with selected secondary Mike in Codec and digital signal processor DSP with
The input port connection that main Mike is corresponding, thus new main Mike is set.Wherein, digital signal
Processor DSP arranges the process schematic of new main Mike and may refer to Fig. 6.By selected
After secondary Mike is set to main Mike, voice can be carried out by the new main Mike after arranging and send words,
Thus ensure that user can be normally carried out voice call.
During according to the default selected secondary Mike of Mike's order, if step 501 detects

Certainly, Mike's changing method that the embodiment of the present invention provides is also applied for terminal to be needed to carry out
Scene during recording.Concrete, when terminal is recorded, Digital Signal Processing can be passed through
The voltage of the voice signal that device DSP detects main Mike input is the most abnormal, if electric voltage exception, then
Terminal determines that the input signal of main Mike is abnormal, and now, terminal passes through digital signal processor DSP
According to the default selected secondary Mike of Mike's order, and then control selected secondary Mike as main Mike
Carry out voice by coder Codec and send words, such that it is able to solve in many Mikes of prior art
When main Mike occurs abnormal, the problem that terminal can not be normally carried out recording.Different from carrying out voice call
, when being recorded by main Mike, secondary Mike can not work, digital signal processor
DSP carries out noise reduction process also without to the signal of typing, say, that if terminal detects
The voice signal of main Mike input is abnormal, then terminal Mike of can leaving unused is set to main Mike,
So that being recorded by the main Mike after arranging.
The embodiment of the present invention provides a kind of Mike's changing method, is examined by digital signal processor DSP
When measuring the voice signal exception of main Mike input, by different with voice signal in coder Codec
In output port that normal main Mike is corresponding and digital signal processor DSP abnormal with voice signal

The problem of words.
The embodiment of the present invention provides a kind of Mike's changing method, sees Fig. 7, mainly can include with
Lower step:
701, terminal detects main Mike and the language of secondary Mike input by digital signal processor DSP
The matching degree of tone signal, matching degree is the weight by the pitch of voice signal, loudness of a sound and the duration of a sound
Institute is calculated.
In this step, the voice signal that terminal inputs main Mike through coder Codec it
After, the matching degree of the voice signal that can be inputted by main Mike and secondary Mike, in order to main wheat
Gram signal is the most abnormal.Such as, digital signal processor DSP can pass through voice recognition mode
The voice signal main Mike and secondary Mike inputted enters with the user speech reference signal of typing in advance
Row coupling, and each Mike of weight calculation according to speech signal parameter pitch, loudness of a sound and the duration of a sound is defeated
The matching degree of the voice signal entered.Exemplary, pitch, loudness of a sound, the duration of a sound weight respectively can
Think 0.5,0.2,0.3, the voice that digital signal processor DSP can input according to each Mike
The characteristic of signal obtains each parameter with user speech reference signal matching rate, the most a certain wheat
Gram input the pitch of voice signal with the matching rate of the pitch of user speech reference signal be
85%, the matching rate of loudness of a sound is 73%, and the matching rate of the duration of a sound is 90%, then this Mike inputs
Voice signal is 84.1% with the matching degree of user speech reference signal, i.e.
85%*0.5+73%*0.2+90%*0.3=84.1%.In like manner, the voice of arbitrary Mike input can be calculated
The matching degree of signal.
If 702 terminals detect, by digital signal processor DSP, the language that arbitrary secondary Mike inputs
The matching degree of tone signal is more than the matching degree of the voice signal of main Mike input, then terminal determines master
The voice signal of Mike's input is abnormal.
After the matching degree of the voice signal obtaining arbitrary Mike input in step 701, if detection
To the matching degree of voice signal of arbitrary secondary Mike input more than the voice signal of main Mike input
Matching degree, then show that the user voice signal of this secondary Mike typing is believed than the voice of main Mike's typing
