Summary of the invention
The object of the present invention is to provide a kind of vehicle-mounted speech recognition control system and control method thereof that can realize acoustic control.
For achieving the above object, a kind of vehicle-mounted speech recognition control system provided by the invention, this system comprises voice acquisition module, voice acquisition module links to each other with execution module by speech processing module, the output electric signal drove the execution module action to speech processing module by speech processing module after voice acquisition module detected the corresponding voice signal that the user sends.
Another program of the present invention provides a kind of vehicle-mounted voice identification control method, and it comprises the following steps:
(1) sets the title of vehicle and the input time that voice execute instruction;
(2) detect whether the phonetic order input is arranged, if testing result then continues to detect for not;
(3) if the result who detects in the step (2) is for being whether have the phonetic order input that contain vehicle title, if testing result is then returned step (2) for denying if then detecting;
(4) if the result who detects in the step (3) for being, is then called by voice cue module and replys instruction, prompting user input voice execution command;
(5) judge whether the user imports the voice execution command in the input time of voice execution command, if judged result is then returned step (2) for not;
(6) if the result who judges in the step (5) for being, judges then whether the voice execution command is included in the phonetic order data bank, if judged result is not for, then being executed instruction by these voice of voice cue module prompting user does not exist and returns step (2);
(7) if the result who judges in the step (6) is for being then to carry out this voice by execution module and execute instruction.
According to the present invention, detect the voice signal that the user sends by voice acquisition module, and the output electric signal is to speech processing module, after speech processing module judgment processing, voice cue module prompting user input voice execution command, speech processing module output electric signal is carried out corresponding voice execution command to execution module by execution module.The user just can realize the function that in the past needed M/C to realize, the potential safety hazard of having avoided chaufeur to cause owing to dispersion attention by calling out vehicle title, exhalation related voice execution command in startup procedure.
Description of drawings
Fig. 1 is a functional block diagram of the present invention;
Fig. 2 is a workflow diagram of the present invention.
The specific embodiment
A kind of vehicle-mounted speech recognition control system, comprise voice acquisition module 10, the mouth of voice acquisition module 10 links to each other with the input end of speech processing module 20, speech processing module two-way output in 20 fens, one the tunnel links to each other with the input end of voice cue module 30, another road links to each other with the input end of execution module 40, as shown in Figure 1.The output electric signal was judged 40 actions of rear drive execution modules to speech processing module 20 through speech processing module 20 after voice acquisition module 10 detected the corresponding phonetic order that the user sends, and carried out corresponding voice execution command.
In conjunction with Fig. 1, described voice acquisition module 10 execution modules 40 are provided with at least eight executive's interfaces, are used for linking to each other with external equipment, have also reserved eight expansion executive's interfaces on execution module 40, are used for coupled system upgrading back and use.
In conjunction with Fig. 1, be provided with the close friend in the voice cue module 30 and reply phonetic order, for example: " Whatcan I do for you? " etc. relevant hint instructions, be provided with phonetic order data bank 21 in the speech processing module 20, have 15 the voice execution commands that can discern, can Gong call in the phonetic order data bank 21:
1, Music: calling system carries audio player
2, Film: calling system carries video player
3, TV: carry out and play television mode
4, GPS: call GPS navigation software
5, Telephone: call car phone
6, Email: check E-MAIL
7, Word: calling word process software
8, Excel: call spreadsheet
9, PPT: call the filmstrip process software
10, Internet: call explorer
11, Up: the current media broadcast sound volume adds
12, Down: the current media broadcast sound volume subtracts
13, Stop: current media is play and is suspended
14, Play: current media is play and is continued
15, Reversing Camera: the reversing shooting shows
Below in conjunction with Fig. 2, workflow of the present invention is further described:
This control system has three kinds of mode of operations: silent status, interaction mode and executing state.Wherein, silent status is meant the state whether native system detects the phonetic order input; Interaction mode is meant the state that exchanges between user and the system; Executing state is meant that system carries out the state of voice execution command.Execution module 40 performed functions also can realize by touch-screen, keyboard or M/C.
At first, after the system start-up, operation display interface, and loading speech recognition engine, be set by the user the input time of vehicle title and voice execution command, wherein, " title of vehicle " is the title of the applied vehicle of native system, the time that " input time of voice execution command " starts at when being meant from voice cue module 30 prompting user input voice execution commands, for ease of explanation, suppose that the vehicle name that native system sets is called easter, be 20 seconds the input time of voice execution command, detect by voice acquisition module 10 whether the phonetic order input is arranged, whether if voice acquisition module 10 has detected the phonetic order input, then further detecting this phonetic order is whether " easter " or this phonetic order comprise " easter ", opposite, if voice acquisition module 10 does not detect the phonetic order input, then be in the cycle detection state always;
Secondly, if when voice acquisition module 10 detects customer call vehicle title " easter ", voice cue module 30 calls at random that the close friend replys language, as " What can I do foryou? ", and the prompting user can import the voice execution command;
Once more, if in the promptly 20 seconds input time of voice execution command, suppose user's voice execution command " Music " or " Music please " of breathing out, it is speech processing module 20 that system enters speech recognition engine, and whether retrieval has this voice execution command in phonetic order data bank 21; If the user is exhalation voice execution command in the promptly 20 seconds input time of voice execution command not, system returns silent status and detects whether the phonetic order input is arranged;
At last,, then call execution module 40, carry out this instruction if in phonetic order data bank 21, retrieve this voice execution command; If do not retrieve this voice execution command, voice cue module 30 these execution commands of prompting do not exist, and return silent status and detect whether the phonetic order input is arranged.Because the voice of being supposed execution commands " Music " are in phonetic order data bank 21, speech processing module 20 drives execution module 30 actions, calling system carries audio player, owing to comprise voice execution commands " Music " in " Music please ", user's exhalation " Music please " can be opened the audio player that system carries equally.
In sum, core of the present invention is to detect by the voice that 10 couples of users of voice acquisition module send, and 20 judgements of input speech processing module, if meet the phonetic order in the phonetic order data bank 21, drive execution module 40 actions, carry out the corresponding instruction function.The present invention discerns, judges and carry out by the voice that the user is sent, can be implemented in the mutual function of man machine language in the vehicle control syetem, reduce the M/C step, the potential safety hazard of having avoided chaufeur to cause owing to dispersion attention in startup procedure has improved safety and the convenience driven.
