Accompanying drawing explanation
Fig. 1 is that in the embodiment of the present invention, Application on Voiceprint Recognition automobile accessing method user logins schematic diagram；
Fig. 2 is Application on Voiceprint Recognition automobile accessing method Database step schematic diagram in the embodiment of the present invention.
Detailed description of the invention
By describing the technology contents of the present invention, structural feature in detail, being realized purpose and effect, below in conjunction with embodiment
And coordinate accompanying drawing 1 and accompanying drawing 2 to be explained in detail.
Referring to Fig. 1, one preferred embodiment of the present invention is
A kind of Application on Voiceprint Recognition automobile accessing method, comprises the following steps:
Step 101: gather and login information
It is acquired by the voice messaging of the sound collector user to logining, obtains logining audio files；Institute
State sound collector and can select microphone, noise reduction microphone and pick up.
Step 102: extract the vocal print feature logining audio files
When extracting audio files vocal print feature, first original audio is carried out pretreatment, add including sampling, quantify, estimating
Heavily process, then extract audio files and include tone and tamber characteristic；Pretreatment enhances the feature of audio files；
With this, audio files of logining extracted can be sent to high in the clouds processor, high in the clouds processor processes and logins audio files
Obtain vocal print feature, vocal print feature is sent back on on-board storage carrier；High in the clouds energy force rate is big, substantially increases and processes data
Accuracy and speed；Use in some embodiments, extraction is logined audio files and sends in-vehicle processor, in-vehicle processor to
Process is logined audio files and is obtained vocal print feature, vocal print feature is returned on vehicle-mounted memory carrier；Decrease in data transmission and meet
To the problem such as delaying.
Step 103: be numerical string by vocal print Feature Conversion
Contrast with standard vocal print digital document according to vocal print feature, obtain corresponding with logining audio files logining number
Value string；The corresponding special value of each vocal print feature of described standard vocal print digital document, these standard vocal print digital documents
It is all to pre-set in high in the clouds or vehicle-mounted memorizer with corresponding numerical value；Convert sound into numerical string, so easy
Information of the logining comparison in later stage.
Step 104: contrast logining numerical string with the numerical string in data base
Contrasting with the numerical string in data base according to described numerical string of logining, the numerical string in these data bases is thing
The vocal print numerical string of the user being first already registered for, if there being the numerical string of coupling, enters the corresponding user identity of acquisition,
To differentiate that this user is for registration user；If not mating numerical string, returning collection and logining information, i.e. can be judged as non-registered
User.
Step 105: obtain corresponding user identity
Numerical string according to coupling obtains relative users identity information, obtains corresponding authentication result；According to the number obtained
Value string information, just can obtain the user profile of correspondence in systems.
Step 106: login successfully:
Give user according to authentication result and automobile controlled right accordingly, and show relevant logining at automobile display platform
Success, welcomes the information of operation automobile.
The present embodiment uses and first converts the audio into as numerical string, then contrasts according to numerical string, which simplify sound
The contrast of sound, improves again the accuracy of contrast simultaneously, thus improves vehicle safety.
The another kind of preferred embodiment of the present invention, the present embodiment is otherwise varied with other embodiments the most on the database,
The problem mainly solving to set up data base accurately；
It is described as follows with reference to Fig. 2: its described Database step of described Application on Voiceprint Recognition automobile accessing method includes:
Step 200: login data base；
The user needing administration authority inputs correct manager's numerical ciphers and the sound of manager, only through double
After re-authentication, just have the right to carry out user's registration, it is ensured that manager's control to automobile management, it is ensured that the safety of automobile.
Step 201: registration user profile:
The user needing registration is set up related text archive information.
Step 202: collection user voice file:
By sound collector, log-on message is acquired, obtains registering audio files；Described sound collector is permissible
Select microphone, noise reduction microphone etc..
Step 203: the registration audio files feature that extraction gathers:
With this, audio files of logining extracted can be sent to high in the clouds processor, high in the clouds processor processes and logins audio files
Obtain vocal print feature, vocal print feature is sent back on on-board storage carrier；Or, extraction is logined audio files and sends to vehicle-mounted
Processor, in-vehicle processor process is logined audio files and is obtained vocal print feature, vocal print feature returned on vehicle-mounted memory carrier.
Step 204: by audio files Feature Conversion for registering numerical string:
Contrast with standard vocal print digital document according to vocal print feature, obtain corresponding with logining audio files logining number
Value string, each standard vocal print feature correspondence special value string of described standard vocal print digital document.
Step 205: judge whether for the first time or second time collection log-on message:
Gather information of registered users twice, if gathering log-on message, then the registration number that will collect for the first time for the first time
Value string is deposited in memorizer 1；If second time gathers log-on message and is then stored in by the registration registration numerical string of second time collection
In memorizer 2；Twice collection improves the identification accuracy to user.
Step 206: store the registration numerical string gathered for the first time, and carry out second time log-on message collection.
Step 207: store the registration numerical string that second time gathers.
Step 208: the second time collection registered in numerical string and bin 2 that the first time in contrast bin 1 gathers
Registration numerical string, obtain judged result；So may determine that whether twice collection is same registration user, improve collection
Accuracy,.
Step 209: if the judged result of step 208 is inconsistent, then returns and newly gather user profile, removes memorizer 1
With the data in memorizer 2, and remove acquisition and recording, be equivalent to gather from new；Twice contrast is inconsistent, gathers from new, row
Except interference, it is to avoid false registration.
Step 210: if the judged result of step 208 is consistent, then by the numerical string in memorizer 1 or bin 2 with
Numerical string in data base contrasts, and the numerical string in these data bases is the vocal print numerical value of the user being already registered in advance
String, obtains judged result；If numerical value is consistent with certain numerical value in the numerical string in data base in memorizer 2, then it is judged as
Registration user, it is to avoid repeated registration；.
Step 211: if the judged result of step 210 is not for mate numerical string, then this registers user as user, and registration should
Character file information and corresponding numerical string.
Step 223: if the judged result of step 210 is for there being coupling numerical string, then this registers user as registered users, then
Not registration.
Step 222: display registering result, terminates registration.
The present embodiment uses the logon mode converting sound into numerical string, improves the definitiveness of log-on message, is stored in
Data base, logins documents during audio files contrast as the later stage.
The foregoing is only embodiments of the invention, not thereby limit the scope of the claims of the present invention, every utilize this
Equivalent structure or equivalence flow process that bright description and accompanying drawing content are made convert, or are directly or indirectly used in other relevant skills
Art field, is the most in like manner included in the scope of patent protection of the present invention.
