Embodiment

The invention provides a kind of sound control method and system of electronic equipment, for making object of the present invention, technical scheme and effect clearer, clear and definite, referring to accompanying drawing examples, the present invention is described in more detail.

Electronic equipment of the present invention is the electronic equipment that comprises voice messaging collecting unit, as the mobile communication equipment with microphone (mobile phone, intercom), digital electronic goods, notebook computer, Portable intelligent terminal (computing machine), electronic product and household appliances etc.Described voice messaging collecting unit can be internal or external microphone, also can gather the device of recording voice voice messaging for other.

As shown in Figure 1, the sound control method of the electronic equipment that first embodiment of the invention provides, comprises step:

S10: the voice messaging that gathers user;

When needs are controlled electronic equipment by voice, can trigger voice control function by touching entity or the virtual key of described electronic equipment.After voice control function is triggered, described voice collecting unit starts to detect phonetic entry, user can say phonetic order information near microphone the sounding of described electronic equipment, and described electronic equipment is recorded and stores the user's who receives voice messaging.

S20: the vocal print feature of extracting user from described voice messaging;

Concrete, first the voice messaging obtaining is carried out to the processing such as A/D conversion, end-point detection, pre-emphasis, minute frame, autocorrelation sequence, Fourier transform, extract user's vocal print characteristic parameter, such as frequency spectrum, cepstrum, resonance peak, fundamental tone, lexical feature and prosodic features etc. represent the characteristic parameter of bion characteristic.

S30: described vocal print feature is mated with vocal print template pre-stored in vocal print template base;

Described vocal print template base, the voice messaging that can carry out repeatedly user by described voice collecting unit extracts that vocal print characteristic synthetic generates, and also can import by outside, and be stored in the storage area of described electronic equipment.Certainly, when described electronic equipment uses jointly for multi-user, described vocal print template base just stores the vocal print template of a plurality of validated users.When carrying out voice print matching, described vocal print feature and all vocal print template are compared one by one.

S40: when described vocal print feature and a vocal print template matches, confirm user identity and transfer pre-stored described user's operational order storehouse;

Concrete, if both similarities surpass reservation threshold, the match is successful to judge both, just can determine described user profile corresponding to vocal print template that the match is successful, described like this user's authentication is passed through; If described vocal print feature is not all mated with vocal print templates all in described vocal print template base, judge described subscriber authentication failure.

After described user's authentication is passed through, described user obtains the rights of using of described electronic equipment, can release described in other operations of setting in advance of electronic equipment or execution; Certainly, if described authentication failure locks electronic equipment, to prevent disabled user's illegal operation.In the present embodiment, after described user's authentication is passed through, also transfer described user's operational order storehouse.

S50: extract voice content from described voice messaging;

When described electronic equipment carries out voice registration, the voice messaging that user is repeatedly inputted carries out calculation process, extracts vocal print feature and then generates vocal print template.Meanwhile, described user's voice messaging is carried out to analyzing and processing, set up acoustic model, match pattern and pronunciation dictionary, and then can generate voice content according to voice messaging analysis.

S60: the phonetic order in described voice content and described user's operational order storehouse is mated;

Equally, described operational order storehouse arranges and generates when carrying out voice registration described user.According to user's actual needs or use habit, described default operational order can be set when user registers voice, also can in use revise according to actual needs.Be understandable that, described operational order includes but not limited to following: move at least one operational order, such as starting camera, transmitted signal and connecting wireless network etc.; Move at least one application program, such as application such as short message, Web banks; Show the application icon that at least one is default, such as showing six conventional application icons; Show most recently used application icon; Show default user interface, such as release word, picture or animation.

S70 a: when operational order in described voice content and described user's operational order storehouse mates, carry out described operational order.

Described electronic equipment is under multi-user's service condition, after a subscriber authentication is passed through, extract described user's operational order storehouse, when mating, described voice content only itself and described user's operational order need to be compared like this, and do not need all users' operational order to compare, improved comparison efficiency and saved the time.

The sound control method of the electronic equipment that the embodiment of the present invention provides, by the vocal print feature of match user, verify the validated user identity of described electronic equipment, effectively prevent disabled user's illegal operation, security and the privacy of described electronic equipment have been improved, voice content by match user carrys out executable operations instruction, has realized voice control.

The process flow diagram of the sound control method of the electronic equipment that Fig. 2 provides for second embodiment of the invention, on above-described embodiment basis, after gathering user speech information step, also comprise step S80: whether the voice messaging of judgement input meets default voice quality, as do not meet S82 and point out user to re-enter voice messaging.In order further to improve comparison efficiency, screening in the present embodiment meets the voice messaging that presets quality requirements, the scope requiring such as loudness and pitch is respectively 6dB-120dB and 300Hz-9kHz, the voice messaging collecting described in only having reaches this voice quality scope, just can further start S2 step, when described voice messaging does not reach while requiring, can't carry out follow-up step but require re-entering voice messaging, avoided without the subsequent step of actual effect and saved time.

On the basis of above-described embodiment, as shown in Figure 3, third embodiment of the invention also provides a kind of speech control system 10 of electronic equipment, and it comprises voice messaging collecting unit 20, vocal print feature extraction unit 30, vocal print characteristic matching unit 40, voice content extraction unit 50, voice content matching unit 60, control module 70 and storage unit 80.
