Fig. 3 is the calcspar of the mobile terminal apparatus that illustrates according to one embodiment of the invention.Please refer to Fig. 3, mobile terminal apparatus 300 has voice-output unit 310, voice receiving unit 320, language understanding module 330 and voice wake module 350.The mobile terminal apparatus 300 of the present embodiment is similar to the mobile terminal apparatus 100 of Fig. 1, and its difference is: the mobile terminal apparatus 300 of the present embodiment has more voice wake module 350.
Voice wake module 350 is in order to judge whether to receive the voice signal with identifying information.In the present embodiment, in the time that voice wake module 350 does not receive the voice signal with identifying information, voice-output unit 310, voice receiving unit 320 and language understanding module 330 can or be closed isotype in standby, and mobile terminal apparatus 300 can not carry out interactive voice with user.And in the time that voice wake module 350 receives the voice signal with identifying information, 300 of mobile terminal apparatus can start voice receiving unit 320 with the voice signal after receiving, and resolve by language understanding module 330, be that mobile terminal apparatus 300 can carry out interactive voice according to this voice signal and user, and also can carry out corresponding to the response operation of voice signal etc.Therefore in the present embodiment, user can be directly in the mode of voice, says the voice (for example specific vocabulary, as name) with identifying information, wakes mobile terminal apparatus 300 up and carries out voice interactive function.In addition, the hardware circuit that the voice wake module 350 of the present embodiment can be combined by or several gate carrys out implementation, can be also to carry out implementation with computer program code.
It is worth mentioning that, because voice receiving unit 320 is to be activated after voice wake module 350 picks out identifying information, therefore language understanding module 330 can avoid non-speech audio (for example noise signals) to resolve.In addition, as long as for example, because voice wake module 350 can pick out the corresponding message of identifying information (the corresponding message of " little madder " this identifying information), can judge that received voice signal has identifying information, therefore voice wake module 350 can not possess the ability that has natural language understanding, and has the consumption of lower-wattage.Thus, in the time that user does not provide the voice signal with identifying information, mobile terminal apparatus 300 can not start voice interactive function, manipulates by voice therefore mobile terminal apparatus 300 is not only easy to use person, can save electrical source consumption yet.
Therefore in the present embodiment, mobile terminal apparatus 300 can judge whether to receive the voice signal (below representing with voice signal V1) that meets identifying information by voice wake module 350, if, mobile terminal apparatus 300 can start voice receiving unit 320 to receive message, and judges by language understanding module 330 whether voice receiving unit 320 receives another voice signal (below representing with voice signal V2) after voice signal V1.If language understanding module 330 judges voice receiving unit 320 and receive voice signal V2, language understanding module 330 can be resolved voice signal V2 and obtain speech recognition result, and judges in speech recognition result whether have and can carry out solicited message.If speech recognition result has can carry out solicited message time, mobile terminal apparatus 300 can be carried out response operation by language understanding module 330, and terminated speech interactive function.
But, if above-mentioned voice receiving unit 320 is after voice signal V1, do not receive another voice signal V2, or, language understanding module 330 is resolved voice signal V2 and the speech recognition result that obtains, do not have can carry out solicited message time, mobile terminal apparatus 300 can be carried out voice dialogue pattern by language understanding module 330, to carry out voice communication with user.Wherein, language understanding module 330 is in the time carrying out voice dialogue pattern, and language understanding module 330 can send the solicited message (be user's intention) of voice answer-back with inquiry user automatically.Now, language understanding module 330 can judge whether the voice signal that user exports meets termination of a session information, or no have can carry out solicited message.If had, can terminated speech dialogue mode, or after carrying out the corresponding solicited message carried out terminated speech dialogue mode; If not, 330 of language understanding modules can continue to carry out voice dialogue pattern, can carry out solicited message until the voice signal that user exports meets termination of a session information or has.
Below the above-mentioned mobile terminal apparatus 300 of arranging in pairs or groups illustrates the method for speech control.Fig. 4 is the flow chart of the speech control method that illustrates according to one embodiment of the invention.Referring to Fig. 3 and Fig. 4, in step S402, voice wake module 350 can judge whether to receive the voice signal (below representing with voice signal V1) that meets identifying information.Specifically, identifying information can be the corresponding default sound of specific vocabulary (for example name), and wherein this default sound can be within special audio scope or specific energy range.That is to say, voice wake module 350 can judge whether to receive the default sound within special audio scope or specific energy range, whether receives the voice signal V1 with identifying information and judge.In the present embodiment, user can set this identifying information by the system of mobile terminal apparatus 300 in advance, for example provide in advance identifying information corresponding default sound, and whether voice wake module 350 can meet this default sound by comparison voice signal V1, judge whether voice signal V1 has identifying information.For instance, suppose that identifying information is the corresponding default sound of " little madder " this name, voice wake module 350 can judge whether to receive the voice signal V1 with " little madder ".
If voice wake module 350 does not receive the voice signal V1 that meets identifying information,, as shown in step S404, mobile terminal apparatus 300 can not start voice interactive function.Because voice wake module 350 does not receive the voice signal V1 that meets identifying information, therefore voice receiving unit 320 is into closed condition or resting state and can carry out the reception of voice signal, therefore the voice signal of the language understanding module 330 in mobile terminal apparatus 300 after can not obtaining resolved.For instance, suppose that identifying information is for " little madder ", if user does not say " little madder " and said other voice such as " Xiao Wang ", voice wake module 350 cannot receive the voice signal V1 that meets " little madder ", therefore the voice interactive function of mobile terminal apparatus 300 can not be activated.
In step S406, in the time that voice wake module 350 judges that voice signal V1 meets identifying information, mobile terminal apparatus 300 can start voice receiving unit 320 to receive message.And language understanding module 330 can, according to the received message of voice receiving unit 320, judge whether voice receiving unit 320 receives another voice signal (below representing with voice signal V2) after voice signal V1.In the present embodiment, language understanding module 330 can judge whether the energy of the received message of voice receiving unit 320 exceedes a set point.If the energy of described message does not exceed set point, language understanding module 330 can judge that this message is noise, uses and judges that voice receiving unit 320 does not receive voice signal V2; If the energy of described message has reached set point, language understanding module 330 can judge that voice receiving unit 320 has received voice signal V2, and then carries out follow-up step according to this voice signal V2.
If language understanding module 330 judges voice receiving unit 320 and do not receive voice signal V2,, as shown in step S408, language understanding module 330 can be carried out voice dialogue patterns.In voice dialogue pattern, language understanding module 330 can send voice answer-back by voice-output unit 310, and can continue to receive and resolve another voice signal from user by voice receiving unit 320, make according to this another voice answer-back or response operation, until language understanding module 330 is judged the voice signal with termination of a session information, or mobile terminal apparatus 300 completed user order or request till.About the detailed step of voice dialogue pattern, will be in rear detailed description (as shown in Figure 5).
If language understanding module 330 judges voice receiving unit 320 and receive voice signal V2,, as shown in step S410, language understanding module 330 can be resolved voice signal V2 and obtain speech recognition result.Language understanding module 330 can receive the voice signal V2 from voice receiving unit 320, and voice signal V2 is divided into multiple segmentation semantemes, and above-mentioned segmentation semanteme is carried out to natural language understanding, to pick out the content in voice signal V2.As the language understanding module 130 of Fig. 1, the language understanding module 330 of the present embodiment can be extracted according to fixing word method the statement of voice signal V2, the instruction or the intention (such as imperative sentence or inquiry sentence) etc. that are meant to resolve these statements, and judge the meaning of voice signal V2, use and obtain speech recognition result.Wherein, language understanding module 330 can be passed through semantic database 306, and which instruction the segmentation semanteme that comes to be divided in voice inquirement signal V2 is corresponding to, and above-mentioned semantic database 306 can record the relation of various segmentations semantemes and various command.
