Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are some of the embodiments of the present invention, instead of all the embodiments.Based on this hair
Embodiment in bright, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, shall fall within the protection scope of the present invention.
Referring to Fig.1, the step flow chart of one of embodiment of the present invention microphone fault detection method is shown.The party
Method is applied to mobile terminal, and specific steps include:
Step 101: in the case where microphone starting, obtaining the output signal of the microphone.
In concrete application, the embodiment of the present invention can be applied to mobile terminal, and mobile terminal includes but is not limited to mobile phone, puts down
Plate computer, laptop, palm PC, car-mounted terminal, wearable device and pedometer etc..
In concrete application, microphone can be silicon microphone either other kinds of microphone, the embodiment of the present invention pair
Microphone is not specifically limited.
It may include multiple microphones in some scenes, in mobile terminal, as shown in Fig. 2, can in multiple microphones
With there are main microphon 10 and secondary microphone 20, main microphon can be used for conventional call, recording etc., and secondary microphone can be with

Embodiment in, the microphone for needing fault detection can be defined in the terminal, need the wheat of fault detection as being arranged
The detection mark of gram wind, only in the case where defining the microphone for needing fault detection starting, just acquisition microphone is defeated
Signal out.
In concrete application, the scene of microphone starting has very much, for example, mobile terminal opens call or sound-recording function,
Or third party software calls microphone to complete certain functions, such as the video or phonetic function of social software, opens in microphone
When dynamic, usually mobile terminal user carries out voice input, therefore, the output signal of available microphone.
Step 102: in the case where the output signal meets the first preset condition, determining that the microphone failure is gone forward side by side
Row is reminded.
In the embodiment of the present invention, if output signal meets the first preset condition, it may be said that failure has occurred in bright microphone, into
And microphone failure prompting can be carried out automatically.
In concrete application, if microphone does not have failure, usual output signal can be normal voice signal, or mix
The voice signal of some noise signal.If microphone breaks down, microphone is likely to occur failure in the terminal
Reason can have: since microphone film rupture causes microphone no signal to export, then signal output waveform amplitude is close to 0；By
Make output signal cause voice to be blanked there are the random noise of duration extremely in microphone, is presented as that recording is only capable of listening
It makes an uproar on earth, voice is faint or does not have voice；Since microphone makes the sound of output less than normal extremely, normal talking/recording is influenced
Effect；Since microphone pickup hole is blocked, the voice signal of input is weaker, and the signal for causing microphone to export is very weak, approximate
It is exported in no signal.
In the case where above-mentioned several microphone failures, common feature is using microphone records normal sound signal
In the case of microphone non-output signal or the efficient voice of output signal it is less.It therefore, can be by by output signal and the
The matching of one preset condition, judges whether microphone breaks down.
In practical application, the first preset condition can be set according to actual application scenarios, such as the first default item
Part may is that there is no voice signal, output signals, and mistake etc. occurs in output signal, as long as the first preset condition can be used for
Determine whether output signal is normal, and the embodiment of the present invention is not specifically limited in this embodiment.
In concrete application, the mode for carrying out the prompting of microphone failure may is that be popped up in the user interface of mobile terminal
Prompting frame prompts user's microphone to break down in prompting frame by text, picture, sound, video etc..Carry out microphone event
The mode of barrier prompt is also possible to: carrying out corresponding voice prompting, vibration prompt, the prompt of flashing device according to presetting
Deng；It is appreciated that the carry out microphone fault cues adapted to can be arranged according to actual application scenarios in those skilled in the art
Mode, the present invention is not especially limit this.
In practical application, if output signal is unsatisfactory for the first preset condition, it may be said that without discovery wheat in bright preliminary judgement
Gram wind failure can terminate this microphone fault detection, the present invention is not especially limit this without prompt.
In conclusion can detecte the starting situation of microphone in the embodiment of the present invention, the case where microphone starts
Under, the output signal of microphone is obtained, in the case where the output signal meets the first preset condition, determines microphone failure simultaneously
It is reminded, i.e., in the embodiment of the present invention, mobile terminal can be automatic to execute to microphone according to the starting situation of microphone
Fault detection, and fault cues are carried out, detection process will not be perceived by the user, and event is only carried out when detecting microphone failure
Barrier prompt, therefore user only needs to know that microphone breaks down according to prompt, significant increase mobile terminal user Mike
The convenience of wind fault detection.
Referring to Fig. 3, the specific steps flow chart of one of embodiment of the present invention microphone fault detection method is shown.
Specific steps include:
Step 201: in the case where microphone starting, obtaining the output signal of the microphone.
It can also include: that front ring is worked as in identification before step 201 as a kind of preferred embodiment of the embodiment of the present invention
Border.
In the embodiment of the present invention, it is contemplated that if microphone is in noisy environment, in the output signal of microphone
There may be a large amount of noise signals, can cause larger interference to the fault detection of microphone, even result in erroneous judgement, therefore,
The initial of the microphone fault detection of the embodiment of the present invention is carried out, first identification current environment.
In concrete application, current environment may include quiet environment and noisy environment；Quiet environment specifically can be sound
Noisy value is lower than the environment of preset threshold, correspondingly, noisy environment can be the environment that a riot of sound value is higher than preset threshold；It can
To understand, preset threshold can be set according to actual application scenarios, and the present invention is not especially limit this.
In concrete application, step 201 can be executed in the case where current environment is quiet environment, carry out Mike to be promoted
The accuracy of wind fault detection.
It is appreciated that if microphone is that the occupied output signal extremely short time, got may be not enough to point
Whether analysis microphone breaks down, therefore, in order to obtain can be used for accurately analyzing the output signal of microphone failure, this hair
It is described in the case where microphone starting in a kind of preferred embodiment of bright embodiment, obtain the output letter of the microphone
It number include: to obtain the output signal of the microphone in the case where microphone starts more than the second preset duration.
In concrete application, the starting situation of microphone interface can be detected on the backstage of mobile terminal, if microphone opens
Dynamic duration exceeds the second preset duration, then obtains the output signal of microphone；Wherein, the second preset duration can be according to actual
Application scenarios are set, and the embodiment of the present invention is not especially limited the second preset duration.
Step 202: the actual signal duration of the detection signal is compared with the first preset duration.
In the embodiment of the present invention, the first preset duration can be set according to actual application scenarios, for example, if mobile terminal
In the output signal of microphone is detected by A algorithm, the output signal of fixed input T duration is needed in A algorithm, then first is pre-
If duration can be set as T.
In the embodiment of the present invention, the actual signal duration of output signal if it is greater than or be equal to the first preset duration T, then say
Bright acquisition is effective output signal, can further be detected to the output signal；And the actual signal duration of output signal
If smaller than preset duration, possibly fault detection can not be carried out to microphone by the output signal, it is believed that get
Output signal be invalid output signal, in the embodiment of the present invention, it is contemplated that detect usually to invalid output signal
Accurate detection is unable to get as a result, therefore, after the signal duration of output signal being compared with the first preset duration,
Determine whether to continue output signal detection.
Step 203: the case where the actual signal duration of the output signal is greater than or equal to first preset duration
Under, detect the output signal.
In the embodiment of the present invention, the case where the actual signal duration of output signal is greater than or equal to the first preset duration
Under, it may be said that it is bright to have got effective output signal, therefore can detecte the output signal.
In the embodiment of the present invention, invalid output signal can be filtered out by step 202 and step 203, only to effective
Output signal is detected, and avoids carrying out invalid signal detection calculating, and then save the computing resource of mobile terminal.
In concrete application, if the actual signal duration of output signal is less than the second preset duration, it may be said that bright acquisition is
Valid output signal, can detecte whether microphone is still running the functions such as call or recording, if microphone is still occupied,
The judgment step of step 201 to step 203 can be re-started.
As a kind of preferred embodiment of the embodiment of the present invention, the step of the detection output signal, comprising:
Sub-step A1: the output signal is subjected to framing operation, obtains echo signal.
Sub-step A2: the phonetic feature of each frame of the echo signal is extracted respectively.
Sub-step A3: the phonetic feature is analyzed.
In the embodiment of the present invention, by taking the output signal of T a length of when obtaining as an example, N frame can be divided into output signal, often
The frame length of frame is T/N, wherein N can be set according to the detection algorithm for carrying out output signal detection, the embodiment of the present invention
N is not especially limited.
Using the output signal after progress framing as echo signal, the language of every frame signal of echo signal can be extracted respectively
Sound feature.In concrete application, phonetic feature can be used to indicate that the feature of voice signal or noise signal etc., pass through analytic language
Sound feature can determine whether microphone breaks down.
In the embodiment of the present invention, a kind of method for providing specific detection output signal will be defeated by the detection method
Signal carries out framing operation out, and the phonetic feature for extracting output signal frame by frame is analyzed, therefore available accurate inspection
Survey result.
Step 204: in the case where the output signal meets the first preset condition, determining that the microphone failure is gone forward side by side
Row is reminded.
As a kind of preferred embodiment of the embodiment of the present invention, the phonetic feature includes following at least one: short-time average
Energy, short-time average zero-crossing rate, comentropy, auto-correlation coefficient.
Energy difference phase in concrete application, due to the energy time to time change of voice signal, between voiceless sound and voiced sound
When significant, therefore by analyzing short-time energy and short-time average magnitude, this eigentransformation feelings of voice can be described
Condition, short-time average energy can characterize short-time energy, and short-time average zero-crossing rate can characterize short-time average magnitude.And normal
Voice signal in, occur it is duplicate may be smaller, and in noise signal, occur it is duplicate may be larger, in the concept of entropy
In, for uncertain content, more information is needed to go to determine, information source output is random quantity in information theory, thus its
Degree of indeterminacy can be measured with probability distribution, therefore the usually noise that comentropy is big, the small usually voice signal of comentropy；
And people, in pronunciation, vocal cord vibration sounding, voice can usually embody certain periodicity, noise be do not have it is rhythmic, because
This, can with the auto-correlation coefficient of phonetic feature in output signal it is big be usually voice signal, auto-correlation coefficient it is small be usually
Noise signal.
It is described in the case where the output signal meets the first preset condition based on this, determine the microphone failure
And the step of being reminded, comprising:
It is less than default low energy threshold value, and the echo signal in the short-time average energy of each frame of the echo signal
Each frame short-time average zero-crossing rate be less than preset low zero-crossing rate threshold value in the case where, determine the microphone failure are as follows: wheat
Gram wind ontology failure or microphone path fault, and reminded；
Or,
The default low energy threshold value and default high energy are in the short-time average energy of each frame of the echo signal
It measures between threshold value, and the short-time average zero-crossing rate of each frame of the echo signal is greater than the case where presetting high zero-crossing rate threshold value
Under, determine the microphone failure are as follows: microphone body failure or microphone path fault, and reminded；
Or,
In the case where the comentropy of each frame of the echo signal is greater than presupposed information entropy threshold, the Mike is determined

In the embodiment of the present invention, first by taking short-time average energy and short-time average zero-crossing rate as an example, illustrate to determine microphone
The specific method of failure respectively obtains the short-time average energy En and short-time average of each frame signal of echo signal by calculating
Zero-crossing rate Zn, and be En setting just two decision thresholds TEH and TEL, and TEH > TEL；Correspondingly, Zn setting height two are sentenced
Certainly threshold value TZH and TZL, and TZH > TZL.
If En < TEL, and Zn < TZL, illustrate that the energy of the frame and zero-crossing rate are very low, even equal to 0, it can determine whether that the frame is
Unvoiced segments；If TEL<En<TEH, and Zn>TZH, since the energy of random noise is usually smaller, and zero-crossing rate is higher, therefore can sentence
It is set to noise segment；If En > TEH, and Zn > TZL, then be determined as voice segments.
After each frame signal has all been marked, signal is judged further according to considered repealed scene.If signal there is only
Unvoiced segments illustrate microphone body or microphone access there may be exception, and the output of microphone no signal or sound are less than normal；If
There is only noise segments or voice segments for signal far fewer than noise segment, illustrates microphone body there may be exception, noise disturbs just
Normal call or recording effect.It is appreciated that judging that the process of microphone failure is lost based on several frequently seen user terminal above
Effect mode is actually embodied on the example of each failure and also has subtle difference, but these can be by adjusting detection
Algorithm is adapted to, and principle is all based on the feature whether analysis microphone output signal meets normal speech signals.
It, can be the case where the comentropy of each frame of echo signal be greater than presupposed information entropy threshold based on similar principle
Under, determine microphone failure are as follows: microphone body failure or microphone path fault；In the auto-correlation of each frame of echo signal
In the case that coefficient is less than predetermined coefficient threshold value, microphone failure is determined are as follows: microphone body failure or microphone path fault.
It, further, can be according to the different by TZL of the short-time average zero-crossing rate of each frame of echo signal in concrete application
The voice segments of<Zn<TZH are defined as voiced sound, and the voice segments of Zn>TZH are defined as voiceless sound, can be reduced according to the distribution of unvoiced or voiced sound
Noise segment is mistaken for the probability of voice segments, the present invention is not especially limit this.
In the embodiment of the present invention, inventor obtains specific microphone most common failure scene, and root according to a large amount of experiment
Provide the concrete sound feature of extraction according to most common failure scene, and judge microphone whether the specific method of failure,
Verified, determination method through the embodiment of the present invention can determine the microphone of the larger proportion in practical application scene
Failure is a kind of efficient, pinpoint accuracy determination microphone fault method.
It can also include: that display corresponds to the wheat as a kind of preferred embodiment of the embodiment of the present invention, after step 204
