It is in closed state, reduces power consumption.In addition, once get present video information in dormant state, then corresponding function is just
Restarting, such as recording function.
Subsequent audio transfers inquiry and use for convenience, returns so carrying out relevant arrangement to the audio of storage
Class, as shown in Fig. 2, as follows to the method for present video information identification classification:
Step 2100: obtaining the present video information in current environment and Application on Voiceprint Recognition is carried out to be formed to the current audio-frequency information
Current voiceprint.
Wherein, so-called vocal print (Voiceprint) is the sound wave spectrum for the carrying verbal information that electricity consumption acoustic instrument is shown.
The generation of human language is a complicated physiology physical process between Body Languages maincenter and vocal organs, and people makes in speech
Phonatory organ -- tongue, tooth, larynx, lung, nasal cavity everyone widely different in terms of size and form, so any two
Personal voiceprint map is all variant.The existing relative stability of everyone speech acoustics feature, and have variability, it is not absolute
, it is unalterable.This variation may be from physiology, pathology, psychology, simulation, camouflage, also related with environmental disturbances.Although such as
This, since everyone vocal organs are not quite similar, under normal circumstances, people remain to distinguish the sound of different people
Or judge whether be same people sound.
Application on Voiceprint Recognition is it may be said that there are two critical issue, first is that feature extraction, second is that pattern match (pattern-recognition).
About feature extraction: the task of feature extraction is to extract and select have separability strong, steady to the vocal print of speaker
The acoustics or language feature of qualitative high characteristic.Different from speech recognition, the feature of Application on Voiceprint Recognition must be " personalization " feature,
And the feature of Speaker Identification must be " common feature " for speaker.Although current major part Voiceprint Recognition System
All be the feature of acoustics level, but characterize a personal touch feature should be multifaceted, comprising: (1) with the hair of the mankind
The related acoustic feature of the anatomical structure of sound mechanism (such as frequency spectrum, cepstrum, formant, fundamental tone, reflection coefficient), nose
Sound, band deep breathing sound, hoarse sound, laugh etc.；The semanteme that (2) is influenced by socioeconomic status, education level, birthplace etc.,
Rhetoric, pronunciation, speech habit etc.；(3) features such as personal touch or the rhythm influenced by parent, rhythm, speed, intonation, volume.
From the angle that can be modeled using mathematical method, the feature that vocal print automatic identification model can be used at present includes: (1) sound
It learns feature (cepstrum)；(2) lexical characteristics (speaker relevant word n-gram, phoneme n-gram)；(3) prosodic features (utilizes
The fundamental tone and energy " posture " of n-gram description)；(4) languages, dialect and accent information；(5) channel information is (logical using which kind of
Road)；Etc..
According to different mission requirements, Application on Voiceprint Recognition is also faced with a problem of feature selecting or feature are selected.For example, right
" channel " information, in criminal investigation using upper, it is desirable to not have to, that is to say, that it is desirable that influence of the channel to Speaker Identification is weakened, because
It is desirable that regardless of with what channel system, it can be recognized speaker；And on bank transaction, it is desirable to be believed with channel
Breath, that is, wish that channel has larger impact to Speaker Identification, influences so as to reject the brings such as recording, imitation.
In short, preferable feature, it should different speakers can be efficiently differentiated, but can be in same speaker's voice
Opposite stabilization is kept when changing；It is not easy to be imitated or can preferably be solved the problems, such as by other people imitations by other people；With compared with
Good noiseproof feature；…….Certainly, these problems can also go to solve by model method.
About pattern-recognition: for pattern-recognition, there are following a few major class methods:
(1) template matching method: using dynamic time bending (DTW) to be directed at trained and test feature sequence, it is mainly used for solid
Determine the application (usually text inter-related task) of phrase；
(2) arest neighbors method: retaining all characteristic vectors when training, and when identification finds in trained vector recently each vector
K, identified accordingly, the amount of usual model storage and similar calculating is all very big；
(3) neural network method: there are many kinds of form, such as Multilayer Perception, radial basis function (RBF), can explicitly train with
Speaker and its background speaker are distinguished, training burden is very big, and the replicability of model is bad；
(4) hidden Markov model (HMM) method: being ratio usually using the HMM or gauss hybrid models (GMM) of list state
More popular method, effect are relatively good；
(5) VQ clustering method (such as LBG): effect is relatively good, algorithm complexity is not high yet and HMM method cooperate more can be with
Receive better effect；
(6) multinomial classifier methods: there is higher precision, but model storage and calculation amount are all bigger；
(7)……。
Application on Voiceprint Recognition needs the critical issue that solves there are also very much, such as: short speech problem, can with very short voice into
Row model training, and being identified with the very short time, this be mainly sound be not easy to obtain using required；Sound mould
Imitative (or playing a record) problem will efficiently differentiate die sinking imitative sound (recording) and real sound；Target in the case of more speakers
Effective detection of speaker；It eliminates or weakens sound variation (different language, content, mode, physical condition, time, age etc.)
Bring influences；Eliminating channel difference and background noise bring influences；... it is next auxiliary to need to use some other technology at this time
Help completion, such as denoising, adaptive technology.
To speaker verification, it is also faced with a dilemma problem.In general, two of characterization speaker identification system performance
Important parameter is false rejection rate (FalseRejectionRate, FRR) and false acceptance rate
(FalseAcceptationRate, FAR), the former be the real speaker of refusal and caused by mistake, the latter is to receive that collection is outer to be said
Talk about people and caused by mistake, the two is related to the setting of threshold value, the equal value of the two referred to as etc. error rates (EqualErrorRate,
EER).In the state of the art, the two can not reach minimum simultaneously, need to adjust threshold value to meet the need of different application
It asks, for example in the case where needs " ease for use ", false rejection rate can be allowed lower, false acceptance rate will increase at this time, from
And safety reduces；In to " safety " demanding situation, false acceptance rate can be allowed lower, at this time false rejection rate
It will increase, so that ease for use reduces.The former may be summarized to be " peaceful wrong not leakage ", and the latter " can rather leak not wrong ".We are true
The adjustment of positive threshold value is known as " operating point " adjustment.Good system should allow freely adjusting to operating point.
Step 2200: from pre-set voiceprint and prestoring in corresponding relationship between personal information, search and work as
The corresponding current persons' information of preceding voiceprint.
Wherein, after getting current voiceprint, in pre-set voiceprint and the vocal print for prestoring personal information
It is inquired between information, forms two kinds as a result, one is to inquire prestore corresponding with current voiceprint according to the result of inquiry
Personal information, secondly corresponding with current voiceprint prestoring personal information not inquire.
Step 2300: if there is current persons' information of corresponding current voiceprint in prestoring personal information, will deserve
Preceding audio-frequency information store to in personal memory corresponding to current persons' information.
Step 2400: if there is no current persons' information of corresponding current voiceprint in prestoring personal information, by this
Present video information is stored into temporary storage.
Wherein, personal memory and temporary storage for local storage disclosed above and/or external can be deposited
Storage device, i.e. personal memory independently exist with temporary storage；It is also possible to be local storage and/or external deposit
Storage device includes personal memory and temporary storage, i.e. local storage and/or external storage device inherently includes
Two kinds of memories, only according to different situations are stored in corresponding position.
It is selected according to the actual situation；To present video information carry out Application on Voiceprint Recognition, and with prestored personal information
Voiceprint compares, if there is the same vocal print, typing before illustrating, just all audio-frequency informations of this personnel
This is stored to prestore inside personal memory corresponding to personal information, facilitate it is subsequent transfer, realize and sort out；If without one
The vocal print of sample, then explanation is stranger, and subsequent user is needed to sort out at this time, then storage is into temporary storage.
It, can be in idle shape for current persons' information of corresponding current voiceprint is not present in prestoring personal information
State confirms identity by user, and establishes associated profiles, as shown in figure 3, specific personnel identity confirmation method is as follows:
Step 3100: if feeding back into dormant state and non-prestoring personnel's confirmation message.
Wherein, once into dormant state, then non-prestore is fed back automatically by voice broadcast or short message etc. mode
Personnel's confirmation message reminds whether user needs to prestore personnel's progress identity validation to non-before to user.
Step 3200: prestoring personnel's confirmation message according to non-to obtain the current behavior information of active user.
Wherein, obtaining for current behavior information can obtain in such a way that mechanical key triggers, can also be by virtual
The mode of key triggering obtains；The mode of mechanical key triggering, it is current can to obtain this by pressing corresponding triggering case
Behavioural information；The mode of virtual key triggering, can be by pressing relevant virtual triggering key in the interface of corresponding software
It is obtained with realizing.
Step 3300: from the corresponding relationship between pre-set behavioural information and command information, lookup and current line
For the corresponding present instruction information of information；Behavioural information includes confirmation resolution information, and command information includes and confirmation resolution information
Mutual corresponding execution resolution information.
Wherein, it after getting current behavior information, inquires, looks between pre-set behavioural information and command information
After asking command information corresponding with current behavior information, the current behavior information even got is confirmation resolution information, then
