Abstract

The invention discloses a mobile phone unlocking method based on voice recognition, and the method comprises following steps of recording and storing standard unlocking voice; requiring the unlocking voice when requesting the user to actuate the mobile phone; inputting the voice and converting the voice into voice characteristic parameters; and comparing the voice characteristic parameters of the request user with the standard voice characteristic parameters, and enabling successful unlocking if the voice characteristic parameters are identical to the voice characteristic parameters of one authorized user. Due to the adoption of the method, the problem that the unlocking password is easy to decipher or to peer can be overcome, the collected voice information is finally converted to the voice characteristic parameters after being corrected and adjusted, so that the accuracy of the characteristic parameter calculation result is improved, and the reliability of the voice unlocking is further improved; the information content is compared with the voice characteristic parameters, the unlocking can be completed when the inputted voice characteristic parameters completely conform to the standard unlocking voice, the unlocking voice is not easy to decode, the storage security of the private data of the mobile phone is high, and the stored private data of the mobile phone is not easy to leak; and in the unlocking process, the keystroke operation is not needed, so that convenience in use can be realized.

Description

Mobile phone unlock method based on speech recognition
Technical field
The present invention relates to a kind of mobile phone unlock method based on speech recognition.
Background technology
Along with reaching its maturity of speech recognition technology; People utilize the technology of this respect to realize a lot of valuable application, such as voice control Voice-Command (action of the acoustic control system of promptly choosing machine), electronic sound Voice-Text (promptly letting computer read article) or the like.Smart mobile phone (Smartphone) is meant " as PC; have independently operating system; can be by user's program of providing of third party such as install software, recreation service provider voluntarily; come constantly the function of mobile phone is expanded through this class method, and can realize the general name of this type mobile phone that wireless network inserts through mobile communication network ".Along with the continuous development of science and technology and improving constantly of people's living standard, the use of smart mobile phone is more and more universal, has become an important component part of people's daily life.
At present, the function of smart mobile phone from strength to strength, the machine master is also increasingly high to the requirement of mobile phone safety in utilization, the selection of release mode has determined the safe in utilization of mobile phone to a certain extent.Nowadays on the market most release modes that adopt unlock password of smart mobile phone; Promptly through the release of comparing behind the key feeding cipher; We know that the password of being made up of numeral or alphabetic character string is easy to be decrypted, and is also peeped by other people easily when using in public places; In case password is known by other people, the private data of mobile phone the inside will be revealed.
Develop rapidly along with the smart mobile phone application; Also there are some voice release softwares to come out on the application market; Yet traditional following problem of voice release software ubiquity: the voice messaging that (1) collects does not pass through correction form signals and adjustment, and the signal that directly converts digital quantity into transfers to processor; Cause the result of calculation poor accuracy of voice signal speech characteristic parameter, and then influenced the reliability of voice releases.(2) only comprise the information content of voice in the traditional speech characteristic parameter, and do not comprise user's tamber characteristic, that is to say; As long as right you are for the information content; No matter be authorized users, can accomplish release, the same with unlock password; The information content of voice also is easy to heard or steal that by other people the mobile phone safety in utilization is still relatively poor.
Summary of the invention
The objective of the invention is to solve the deficiency of prior art, provide a kind of and for unlock password, can effectively avoid password to be decrypted or the quilt information contents that spy on, simultaneous verification user release voice and the mobile phone unlock method based on the speech recognition multi-angle tamber characteristic, that release accuracy high reliability is good, that can effectively ensure mobile phone information safety, easy to use.
The objective of the invention is to realize through following technical scheme: based on the mobile phone unlock method of speech recognition, it may further comprise the steps:
(1) typing standard release voice are also preserved:
S101: confirm authorized users, promptly have the user of voice release authority;
S102: typing is authorized to user's voice and obtains its speech characteristic parameter, and it may further comprise the steps again:
A, the collection of voice collecting device are authorized to user's voice, and through signal adjustment circuit it are adjusted;
B, adjusted voice messaging convert digitized speech information into through analog to digital conversion circuit;
C, digitized speech information convert speech characteristic parameter into through the characteristic parameter change-over circuit;
S103: will be authorized to the user's voice characteristic parameter and be stored in the memory device, and be authorized to user's voice and be defined as standard release voice;
Eject the release interface when (2) asking the user activation mobile phone, require the input voice to carry out release;
(3) the request user is to voice collecting device input voice, and this voice messaging converts digitized speech information through signal adjustment circuit adjustment back into by analog to digital conversion circuit, converts this request user's voice characteristic parameter into through the special parameter change-over circuit again;
The speech characteristic parameter of the standard release voice that (4) will ask to preserve in user's voice characteristic parameter and the memory device is compared; If this speech characteristic parameter is authorized to the identical then release of user's voice characteristic parameter success with one of them, get into the mobile phone operation interface; If this speech characteristic parameter and any one are authorized to all inequality then release of user's voice characteristic parameter failure, mobile phone rests on the release interface.
Signal adjustment circuit of the present invention is carried out pre-filtering, preemphasis, windowing, is added any one or multiple combination in frame and the denoising operation voice messaging.
Speech characteristic parameter of the present invention comprises any one or the multiple combination in MFCC coefficient, differential coefficient, amplitude parameter, frequency parameter, tone color waveform parameter and the human auditory system model relevant parameter.
The invention has the beneficial effects as follows:
(1) replaces traditional character string unlock password, overcome unlocking pin and be prone to the problem that is decrypted or spies on, improved the fail safe that mobile phone uses;
(2) voice messaging that collects finally converts speech characteristic parameter into through correction form signals with after adjusting, and has improved calculation of characteristic parameters result's accuracy, and then has improved the reliability of voice releases;
(3) not only the information content of voice is verified; And from the tamber characteristic of a plurality of angles checking voice; When having only the information content and tamber characteristic all to conform to standard release voice, could accomplish release, the release voice are difficult for being decrypted; The fail safe that the mobile phone private data are preserved is higher, is difficult for revealing;
(4) mobile phone ejects the release interface automatically when activating, and release software begins to gather voice, and aligning voice collecting microphone is said the release voice and got final product, and need not any button operation, and it is extremely convenient to use.
