comparing and recognizing the voice digital signal data with the voice recognition model database prestored in the storage by the voiceprint recognition processor to obtain a voice target character instruction, and selecting whether to call the user signature handwriting information temporarily stored in the storage module or not through the character instruction; when the voice instruction of the user is an instruction for calling the user signature handwriting information, the voiceprint recognition processor calls the user signature handwriting information and converts the user signature handwriting information into a writing track, and the operation of the Y-direction stepping motor, the X-direction stepping motor and the steering engine is controlled by the controller to control the writing pen to write along the writing track; after writing, automatically deleting the signature handwriting information of the user;
and sixthly, when the voice instruction of the user is an instruction of not calling the user signature handwriting information, automatically deleting the user signature handwriting information, interacting the voice print recognition processor with the user through the loudspeaker prompt, transmitting the voice analog signal data of the user collected by the microphone to the storage module, converting the voice analog signal data into voice digital signal data, calling a voice recognition model database prestored in the storage module, comparing and recognizing the voice digital signal data to obtain voice target characters, converting the voice target characters into writing tracks, and controlling the operation of the Y-direction stepping motor, the X-direction stepping motor and the steering engine to control the writing pen to write along the writing tracks through a controller.
7. The method as claimed in claim 6, wherein the remote voice recognition automatic signing apparatus further comprises: in the third step, the remote server cannot confirm that the voice print information is consistent with the voice print information reserved by the user after comparing the voice print information, the identity of the user cannot be confirmed, at the moment, the remote server transmits the information which cannot be confirmed by the user information to the voice print recognition processor through a network module, at the moment, the voice print recognition processor can only call a pre-stored voice recognition model database in the storage module, the voice print recognition processor starts the loudspeaker and the microphone to interact with the user, and the user sends out voice to the microphone through voice according to the prompt tone preset by the loudspeaker; the voice simulation signal data of the user collected by the microphone are transmitted to the storage module and converted into voice digital signal data, the voice recognition model database prestored in the storage module is called to be compared and recognized to obtain voice target characters, the voice target characters are converted into writing tracks of conventional characters, and the writing tracks are controlled by the controller, the Y direction stepping motor, the X direction stepping motor and the steering engine are operated to control the writing pen to write along the writing tracks.
