Mobile phone, flat board etc.), terminal (such as PC, notebook computer), etc..
Reference picture 1, the sound control method first embodiment of the present invention is proposed, the described method comprises the following steps：
S11, receive phonetic order.
Alternatively, electronic equipment receives phonetic order by a microphone.Now, electronic equipment can only in the same time
Receive the phonetic order sent by a user.
Alternatively, electronic equipment receives phonetic order by the microphone array being made up of at least two microphones.Now,
Electronic equipment can receive at least two phonetic orders sent by least two users in the same time.Specifically, electronics is set
Standby to receive voice signal by microphone array, the voice signal includes ambient noise and is simultaneously emitted by by least two users
Phonetic order, and the voice signal to receiving carries out speech Separation (such as utilize FastICA algorithms carry out speech Separation),
Obtain at least two phonetic orders.
For example, it is assumed that there is n sound source signals s1、s2、s3……sn, microphone array shows m (m >=n) individual microphone, and A is
The position hybrid matrix of microphone array, the voice signal that microphone array receives are X, then have X=As, that is, X(i)=
As(i)。
N phonetic order is isolated from voice signal using based on maximum quick ICA (FastICA) algorithm of negentropy,
Utilize formula Y=WTX, first solve W：
(1) data prediction：Zero averaging, albefaction；
(2) initialization vector W；
(3) independent element number n to be separated, first is first separated, p=1；
(4) W values are updated：W=E { zg (wTz)}-E{g′(wTz)}w；
Wherein, g (y)=tanh (ay), 2 >=a >=1, a typically takes 1；
(5) orthogonalization：
(6) W is standardized after iteration every time：W=w/ | | w | |；
(7) (4)~(6) are repeated, until W convergences, as wp；
(8) P=p+1, (4)~(7) are repeated, until p=n, calculates the w of all independent elements；
Finally, formula Y=W is utilizedTX, all n phonetic orders are solved, that is, isolate each phonetic order.
S12, the vocal print feature for extracting phonetic order.
In this step S12, electronic equipment carries out Application on Voiceprint Recognition to phonetic order, extracts the vocal print feature of phonetic order.
When phonetic order at least two, then the vocal print feature of each phonetic order is extracted respectively.Preferably, electronic equipment can
To carry out Application on Voiceprint Recognition to phonetic order using GMM-UBM (gauss hybrid models-universal background model), vocal print spy is extracted
Sign, obtains corresponding characteristic parameter.
S13, the authority information according to corresponding to vocal print feature matches phonetic order.
In the embodiment of the present invention, electronic equipment has prestored at least two vocal print features, and each vocal print feature is provided with corresponding
Authority information.For example, electronic equipment can be trained using GMM-UBM to user speech, the sound of user speech is extracted
Line feature, and its corresponding characteristic parameter is preserved, corresponding authority information is set.
Authority information described in the embodiment of the present invention, one kind or two among Permission Levels and extent of competence can be included
Kind.For example, to there is the smart machine of security requirement, authority classification management can be carried out according to vocal print feature, by Permission Levels
Order from high to low is divided into super authority, common authority and lack of competence.Wherein, equity stock is limited to the use of non-typing vocal print feature
The authority at family, have no right to be limited to the authority of the user corresponding to the vocal print feature that is drawn into the vocal print feature of typing in blacklist,
Super authority is the authority of the user corresponding to the vocal print feature not being drawn into the vocal print feature of typing in blacklist.It is super
Authority can also be further subdivided at least two grades, such as be divided into tetra- grades of A, B, C, D, and authority reduces successively.
Electronic equipment can be that the vocal print feature of typing electronic equipment and non-typing electronics are set when matching authority information
Standby vocal print feature matches different Permission Levels and/or extent of competence respectively, further can also be set for typing electronics
Standby different vocal print features match different Permission Levels and/or extent of competence respectively.
So that authority information includes Permission Levels as an example, electronic equipment can match the power of phonetic order in the following manner
Limit rank：
Alternatively, as shown in Fig. 2 the idiographic flow of electronic equipment matching Permission Levels is as follows：
Whether the vocal print feature of phonetic order is included in the vocal print feature that S101, judgement prestore.When the vocal print feature to prestore
In include phonetic order vocal print feature when, into step S102；When the vocal print feature to prestore includes the sound of phonetic order
During line feature, into step S103.
The vocal print feature of phonetic order is compared electronic equipment with the vocal print feature to prestore, judges the vocal print spy to prestore
Whether vocal print feature that vocal print feature with phonetic order match is had in sign.When having in the vocal print feature to prestore and phonetic order
Vocal print feature match vocal print feature when, then the vocal print feature for illustrating to prestore includes the vocal print feature of phonetic order；When
During the vocal print feature not matched in the vocal print feature to prestore with the vocal print feature of phonetic order, then illustrate the vocal print spy to prestore
Do not include the vocal print feature of phonetic order in sign.
S102, determine that Permission Levels corresponding to the phonetic order are common authority.
When the vocal print feature not matched in the vocal print feature to prestore with the vocal print feature of phonetic order, illustrate the language
The vocal print feature of sound instruction does not have in typing electronic equipment, and electronic equipment then determines that Permission Levels corresponding to the phonetic order are general
Logical authority.
S103, determine that Permission Levels corresponding to the phonetic order are super authority.
When there is the vocal print feature that the vocal print feature with phonetic order matches in the vocal print feature to prestore, illustrate the voice
For the vocal print feature of instruction in typing electronic equipment, electronic equipment then determines that Permission Levels corresponding to the phonetic order are super power
Limit.
Further, electronic equipment can also match according to the corresponding relation of default vocal print feature and Permission Levels
Permission Levels corresponding to the vocal print feature of the phonetic order.For example, super authority further comprise the A that grade reduces successively,
B, tetra- grades of C, D, vocal print feature 1,2,3,4 distinguish corresponding authority grade A, B, C, D, it is assumed that the vocal print feature of phonetic order is
Vocal print feature 3, then it is C level super authorities to match the Permission Levels corresponding to the phonetic order.
When receiving multiple phonetic orders simultaneously, then the Permission Levels of each phonetic order are matched respectively.
Alternatively, as shown in figure 3, the idiographic flow of electronic equipment matching Permission Levels is as follows：
Whether the vocal print feature of phonetic order is included in the vocal print feature that S201, judgement prestore.When the vocal print feature to prestore
In include phonetic order vocal print feature when, into step S202；When the vocal print feature to prestore includes the sound of phonetic order
During line feature, into step S203.
S202, determine that Permission Levels corresponding to phonetic order are common authority.
Step S201 and S202 are identical with abovementioned steps S101 and S102 respectively, will not be repeated here.
S203, judge the vocal print feature of phonetic order whether in blacklist.When the vocal print feature of phonetic order is in black name
When in list, into step S204；When the vocal print feature of phonetic order is not in blacklist, into step S205.
When there is the vocal print feature that the vocal print feature with phonetic order matches in the vocal print feature to prestore, illustrate the voice
In typing electronic equipment, whether electronic equipment continues to judge the vocal print feature of phonetic order in blacklist the vocal print feature of instruction
It is interior.
S204, determine that Permission Levels corresponding to phonetic order are lack of competence.
When the vocal print feature of phonetic order is in blacklist, electronic equipment then determines authority level corresponding to the phonetic order
Not Wei lack of competence, that is, the user for sending the phonetic order haves no right control electronics, and electronic equipment not responds the phonetic order.
S205, determine that Permission Levels corresponding to phonetic order are super authority.
When the vocal print feature of phonetic order is not in blacklist, electronic equipment then determines authority corresponding to the phonetic order
Rank is super authority.
Further, electronic equipment can also match according to the corresponding relation of default vocal print feature and Permission Levels
Permission Levels corresponding to the vocal print feature of the phonetic order.For example, super authority further comprise the A that grade reduces successively,
B, tetra- grades of C, D, vocal print feature 1,2,3,4 distinguish corresponding authority grade A, B, C, D, it is assumed that the vocal print feature of phonetic order is
Vocal print feature 3, then it is C level super authorities to match the Permission Levels corresponding to the phonetic order.
When receiving multiple phonetic orders simultaneously, then the Permission Levels of each phonetic order are matched respectively.
In other embodiments, control authority only can also be authorized to the user of typing vocal print feature, non-typing vocal print is special
The user of sign then lack of competence.
When authority information includes extent of competence, its matching way is similar with the matching way of Permission Levels.For example, when pre-
When not including the vocal print feature of phonetic order in the vocal print feature deposited, the extent of competence for determining the phonetic order is ordinary range；
When the vocal print feature to prestore includes the vocal print feature of phonetic order and the vocal print feature is in blacklist, determine that the voice refers to
The extent of competence of order is lack of competence；When the vocal print feature to prestore includes the vocal print feature of phonetic order and the vocal print feature does not exist
When in blacklist, the extent of competence for determining the phonetic order is super scope.The authority quantity of super scope is more than ordinary range
Authority quantity, lack of competence is that authority is zero, electronic equipment not respond.
When authority information includes Permission Levels and extent of competence, each Permission Levels can correspond to different authority models
Enclose.Wherein, the user being drawn into blacklist, its Permission Levels and extent of competence are lack of competence, i.e. electronic equipment refusal is held
The phonetic order of user in row blacklist.
S14, according to authority information voice responsive instruct.
Alternatively, when authority information includes Permission Levels, if receiving at least two phonetic orders simultaneously, electronics is set
Standby then therefrom selection Permission Levels highest phonetic order, and respond the phonetic order of selection.
Further, when authority information also includes extent of competence, electronic equipment responds the specific of the phonetic order of selection
Flow is：Whether the phonetic order for judging to choose is in its corresponding extent of competence；When the phonetic order of selection is corresponding to it
When in extent of competence, the phonetic order is performed；When the phonetic order of selection is not in its corresponding extent of competence, refusal performs
The phonetic order.
Certainly, in the phonetic order that response is chosen, electronic equipment can also directly perform the phonetic order.
For example, user A, B, C are simultaneously emitted by phonetic order, electronic equipment receives phonetic order A, B, C simultaneously, due to
Family A Permission Levels highest, therefore directly perform phonetic order A.Or first judge phonetic order A whether user A authority
In the range of, phonetic order A is performed when in the extent of competence in user A, when not in user A extent of competence, refusal is held
Row phonetic order A.
Alternatively, when authority information includes Permission Levels, the higher user of Permission Levels is (as having the use of super authority
Family) can be with temporary locking control authority.When receiving phonetic order again after control authority is locked, electronic equipment judges to work as
