Voice-input unit, Audio Processing Unit and DVR unit had not only connected each other but also relatively independent integral body of formation.Fig. 4 a and Fig. 4 b have illustrated the workflow of Audio Processing Unit.After the system initialization, carry out user voice command collection and identification work.After this part powers on, detect whether the user voice command input is arranged,, send control signal corresponding then for the DVR unit as unanimity, and make the corresponding indication of duty if any then comparing with the phonetic order of having stored.Carry out then that order detects to user key-press if no user voice command input or input user voice command be invalid; The user key-press order is then carried out the phonetic order collection for not storaged voice instruction in short button and the storer; If the user key-press order is then deleted original phonetic order, so that typing is carried out in new instruction for for long button.
Below be the explanation of but the utility model voice being controlled the method for manipulating of vehicle-mounted video recorder embodiment:
1, phonetic order collection
When using first, the collection of necessary advanced lang sound instruction.Every phonetic order must successfully be gathered 2 times, surpasses for 5 seconds time≤5 second of each input instruction, and this gathers inefficacy, and system turns back to the preparation work state.The phonetic order acquisition method is as follows: after the energized, short in the instruction acquisition button, the LED5 lamp is bright, then carry out the input of article one instruction (" beginning " instruction), for example " beginning " instruction, say facing to microphone: " beginning ", typing finish then LED5 flicker once, hummer rings one, represent that this gathers successfully, at this moment, LED5 is still bright, import once identical phonetic order again, typing finishes LED5 flicker once, and hummer rings one, represents that this also gathers success, at this moment, article one, instruction is just successfully gathered and is finished, and the LED5 pilot lamp extinguishes, and then the LED6 lamp is with bright, the collection of beginning second phonetic order (" stopping " instruction), method is the same.Below for specifying:
(1) if do not import any phonetic order or instruction acquisition failure in 5 seconds, then system automatically returns to the preparation work state;
(2) LED5, LED6 represent " beginning " and " stopping " respectively.With LED5 is example, and no matter which kind of language the user says, LED5 represents " beginning ", and at this moment, DVR carries out " beginning video recording " action.The rest may be inferred in other instructions.
(3) the phonetic order recognition accuracy of this product is 90%, and just, input needs user voice command of carrying out and the phonetic order difference of having stored to surpass at 10% o'clock, and system does not carry out.Therefore, this product is only carried out specific user's phonetic order.
2, the deletion of phonetic order
Change specific people's phonetic order as need, then need delete original instruction, and then repeat the collection of phonetic order, method is as follows:
The long instruction acquisition button of pressing is more than 5 seconds, and the phonetic order of having stored is all deleted.
3, phonetic order is carried out
At open state, promptly under the preparation work state, the user only need say phonetic order facing to the microphone of product, and then product just begins execution command, need not any manual operation.Below for specifying:
(1) when system is carrying out an instruction, import this identical instruction again, system still carries out the instruction of having carried out, and does not repeat; Unless import other different instruction.
(2) when system cut-off and after quitting work, restart, system no longer carries out the instruction of last time.But be in the preparation work state.
In sum, the speech recognition controlled digital VTR is carried out corresponding operating by the speech recognition user instruction, the advanced person that possesses skills, is easy to realization, reliability height, the outstanding feature such as simple to operate. The particular person voice recognition chip that this video recorder adopts has well anti-hot-tempered performance and shockproof properties, also can effectively work at comparatively noisy environment, is adapted at using in family saloon, public bus, the large, medium and small lorry. But the voice-controllable car video recorder that the utility model provides can not only improve the security of driving greatly, has also increased the operating right control to video recorder, meets every country and the area traffic law aspect car steering fully. This video recorder is not limited to as car video recorder and uses, also can be used as portable video recorder, be applied to all inconvenient manually operated occasions, as when the security personnel when exercising a public function, as long as send phonetic order, just can control portable video recorder and begin video recording, collect simultaneously evidence of crime chasing criminal.
