Number " 123456 ", by once reading aloud, it is possible to known in the audio read aloud from employee using voice
Employee ID is not obtained, and employee's vocal print is obtained by Application on Voiceprint Recognition, is realized and is just once read aloud while obtain
Object identity and vocal print feature, so as to simple flow, improve efficiency.
Following registration and the identifying procedure for describing how to perform gate control system using the present processes respectively：
Registration
If it is desired that being authenticated with gate control system to some destination object, usual destination object will be first in door
Access control system is registered so that gate control system prestores object registration information, subsequently could be right according to this
As log-on message is authenticated to destination object.
Fig. 1 illustrates the register flow path of the gate control system in an example, including following processing：
In a step 101, the audio stream to be registered of destination object is obtained.
For example, still so that the gate control system of a business unit carries out access control to employee as an example, Yuan Gong
When gate control system is registered, the job number " 123456 " of oneself can be read against the microphone of gate control system.
In this example, the employee registered can be turned into destination object, employee reads aloud the audio of oneself job number
Audio stream referred to as to be registered.
After getting audio stream to be registered in this step, then the audio stream is handled, mainly
Including both sides processing, one is to carry out speech recognition to audio stream to obtain object identity, and another is
Application on Voiceprint Recognition is carried out to audio stream and obtains vocal print feature, the processing of these two aspects can be performed successively, or
Perform side by side.It is to be described exemplified by performing side by side in Fig. 1, the steps does not limit execution sequence.
In addition, if gate control system is a system for including multiple equipment, such as including being located at unit door
The audio collecting device such as microphone of mouth, and the equipment for handling collection audio stream is the audio frequency process of rear end
Equipment, then network can be passed through by the audio collecting device of front end after audio stream to be registered is collected
It is transferred to audio processing equipment.
In a step 102, speech recognition is carried out to audio stream to be registered, the voice content that identification is obtained
Object identity as destination object.
Even if for example, the content of speech recognition voice described in computer technology automatic identification people, i.e., by language
Identification process of the sound to content.For example it is the sound that employee reads aloud " 123456 " for audio stream to be registered
After frequency carries out speech recognition, voice content i.e. " 123456 " in the audio stream are obtained, will can be identified
Mark of the obtained content as employee, i.e. employee ID.
In step 103, Application on Voiceprint Recognition is carried out to audio stream to be registered, obtains the audio stream to be registered
Masterplate vocal print feature.
In the present embodiment, Application on Voiceprint Recognition is carried out to audio stream to be registered, i.e., by extracted in audio stream can be only
One identifies the voiceprint of the destination object, such as, vocal print feature vector.Can be final by Application on Voiceprint Recognition
The obtained voiceprint for being subsequently used for certification object is referred to as masterplate vocal print feature.The masterplate vocal print feature
Acquisition can have a variety of methods, by a kind of implementation procedure of Application on Voiceprint Recognition of example in follow-up Fig. 2.
At step 104, it is corresponding by the object identity of the destination object and the masterplate vocal print feature
It is stored in the object registration information.
In this step, the audio stream to be registered " 123456 " that will can be read aloud according to employee, in step 102
The masterplate vocal print feature obtained in object identity and step 103 that middle speech recognition obtains, foundation pair
It should be related to, and both are corresponded to and stored., can be by object identity and corresponding masterplate sound in the present embodiment
Line feature is referred to as the object registration information of the destination object, and the object registration information can be stored in database.
In one example, the processing procedure for Application on Voiceprint Recognition being carried out to audio stream to be registered may refer to Fig. 2.
In step 201, the audio stream to be registered of destination object is obtained.
In step 202, judge whether the audio quality of audio stream to be registered meets quality standard condition.
For example, when the quality of the audio stream of collection is preferable, the effect of Application on Voiceprint Recognition is carried out to audio with regard to more preferable,
Therefore, first the quality of audio stream can be judged before follow-up Application on Voiceprint Recognition is carried out.Such as
The information such as human voice signal's intensity in audio stream, signal to noise ratio can be calculated, to judge whether this section of voice accords with
Quality standard condition is closed, such as, the quality standard condition can set signal to noise ratio in certain scope,
Human voice signal's intensity is higher than certain intensity threshold etc..
If the audio stream of collection is second-rate, quality requirement is unsatisfactory for, can return and perform step 201,
Indicate that the employee registered reads aloud its job number again, i.e. gate control system resurveys audio stream to be registered.
If the quality of the audio stream of collection is preferable, meets quality requirement, then continue executing with step 203.
In step 203, by extracting vocal print feature vector in audio stream to be registered.
In this example, gate control system obtain audio stream to be registered quantity can have it is a plurality of, such as,
In step 201, employee can read the job number of oneself twice, then gate control system will collect two audios
Stream.In this step, gate control system can extract the vocal print feature vector of each of which bar audio stream, should
The extraction of characteristic vector can use a variety of usual manners, no longer be described in detail, such as, can be from audio stream
Extracted in voice signal speech characteristic parameter MFCC (Mel Frequency Cepstrum Coefficient,
Mel-frequency cepstrum coefficient) feature, then using a kind of i-vector (Speaker Identification algorithm) and PLDA
The side such as (Probabilistic Linear Discriminant Analysis, channel compensation algorithm of Application on Voiceprint Recognition)
Method calculates characteristic vector.
In step 204, judge whether the vocal print feature vector of a plurality of audio stream to be registered meets uniformity.
For example, when employee has read aloud the job number of oneself at least twice in step 201, gate control system is adopted
The audio stream of collection is corresponding at least two.In order to ensure the difference of the vocal print feature between a plurality of audio stream
Will not be excessive, it is possible to which the vocal print uniformity carried out between a plurality of audio stream judges.Such as can be with
According to the vocal print feature vector extracted in step 203 by every audio stream, calculate a plurality of audio stream it
Between similarity score.
If the similarity score in the range of certain score threshold, represents to meet similar want between audio stream
Ask, step 205 can be continued executing with；Otherwise, show that this more secondary audio program difference of employee's input are too big,
It can indicate that the employee registered reads aloud its job number, i.e. gate control system again again with return to step 201
Gather audio stream to be registered.
In step 205, it is special according to the vocal print feature of a plurality of audio stream to be registered vector generation masterplate vocal print
Sign.In this step, can according in preceding step respectively to each bar audio stream extract vocal print feature to
Amount is weighted summation, obtains masterplate vocal print feature, and by the masterplate vocal print feature and speech recognition audio
The employee ID that stream obtains, composition object registration information are stored in database.

For example, using the content recognized " 123456 " as the job number of employee, the data in registration are judged
Whether include the job number in the object registration information stored in storehouse.For example the job number recognized can be made
For index, retrieved in database, if it is possible to retrieve the job number, show that the employee has noted
Volume, continues executing with step 304；Otherwise, if not including above-mentioned knowledge in the object registration information of database
It the job number being clipped to, then can confirm that the employee has not yet registered, the employee certification can be prompted to fail, gate inhibition
Do not open, and employee's return to step 301 can also be prompted to resurvey an audio stream, with prevent due to
Error in some processing causes to judge by accident, allows employee to read once its job number again again.
In step 304, Application on Voiceprint Recognition is carried out to audio stream, obtains the vocal print feature of audio stream.
The extraction of the vocal print feature of this step, can use with identical processing method in register flow path, than
Such as, MFCC features are extracted, and vocal print feature vector, the vocal print feature of extraction are calculated using i-vector
The vocal print feature for the audio stream that vector obtains.
In step 305, the object identity that will be obtained in the vocal print feature of audio stream and object registration information
Corresponding masterplate vocal print feature is compared, and judges whether comparison result meets authentication condition.
For example, can be according to the object identity recognized in step 302, by the object registration in database
Masterplate vocal print feature corresponding with the object identity is obtained in information, this is destination object i.e. certification
The vocal print feature that employee stores in registration.Both comparison result can represent with vocal print alignment score,
If alignment score exceedes certain score threshold, it is considered that comparison result meets authentication condition, when
Between the vocal print stored when the vocal print of the employee of preceding certification and registration, both are similar enough, then confirm target
Object is opened by certification, gate inhibition.Otherwise gate inhibition does not open.
