Have single-chip microcomputer in the door bell and button system controller in the door bell device of this realization speech identifying function, described digital signal processor is connected with described single-chip microcomputer.
Audio frequency load module in the door bell device of this realization speech identifying function is microphone.
Digital signal processor in the door bell device of this realization speech identifying function is the digital signal processing dsp chip.
Adopted the door bell device of the realization speech identifying function of this utility model, because wherein with speech identifying function and the ingenious combination of doorbell control function, thereby overcome the existing defective of existing door bell and button system, has simultaneously high intelligence, simple to operate, flexibly, the characteristics such as easy to use, the number that the user only needs voice suggestion to live, system can make corresponding subscriber's extension station ring automatically, thereby prompting has the visitor to arrive, not only simple in structure, and stable and reliable working performance, the scope of application is comparatively extensive, all brings great convenience for people's work and life.
Description of drawings
Fig. 1 is the hardware configuration schematic diagram of the door bell device of realization speech identifying function of the present utility model.
Fig. 2 is the speech recognition principle of work schematic diagram of the door bell device of realization speech identifying function of the present utility model.
Embodiment
In order more clearly to understand technology contents of the present utility model, describe in detail especially exemplified by following examples.
See also shown in Figure 1, this realizes the door bell device of speech identifying function, comprise door bell and button system controller and speech recognition system, wherein, described speech recognition system comprises audio frequency load module, audio codec, digital signal processor and memory module, described audio frequency load module is connected with described door bell and button system controller with digital signal processor by described audio codec successively, and described memory module is connected with described digital signal processor.
Wherein, have single-chip microcomputer in the described door bell and button system controller, described digital signal processor is connected with described single-chip microcomputer, and described audio frequency load module is microphone, and described digital signal processor is the digital signal processing dsp chip.
In the door bell device technical scheme of the utility model realization speech identifying function required for protection; wherein included each functional module all can be corresponding to the particular hardware circuit in the integrated circuit structure in this hardware configuration, so these modules and unit only utilize hardware circuit just can realize.
Simultaneously, in the middle of reality was used, this door bell device comprised audio codec (CODEC) and digital signal processor (dsp chip) and storer.
Comprise the Interface design of CODEC and dsp chip and the Design of Communication Interface between dsp chip and the single-chip microcomputer on this sound identification module hardware, and need to be on DSP the sample circuit of expanded voice signal, realize and single-chip microcomputer between serial communication.
In the actual processing procedure, by voice signal sampling, analog to digital conversion, speech sound signal terminal point detection, speech recognition, the several steps of pattern match, and the communication process between dsp chip and the single-chip microcomputer, namely can realize corresponding voice recognition processing.
Specific implementation:
Finish speech identifying function and include voice signal extraction, voice recognition processing, the comparison of phonetic reference template stores information, specifically see also speech recognition schematic diagram shown in Figure 2.
(1) extract through the voice signal extraction unit that is made of audio decoder in the concrete address of user by microphone input number, and carry out A/D and convert digital signal to;
(2) dsp chip and storer consist of voice recognition processing unit, finish voice training, identification, etc. digital signal processing function, in voice recognition processing unit, in template base, the address number of all resident families of floor is set in advance, be used as the template of coupling;
(3) after voice recognition unit is finished identification, give the single-chip microcomputer of doorbell main frame with the result of the correspondence output of encoding, finish follow-up control by single-chip microcomputer.
The concrete processing procedure of the door bell device of realization speech identifying function of the present utility model is as follows:
From microphone phonetic entry user address number, process through audio codec, mate at digital signal module and the sound template that sets in advance, if the match is successful, then by coding accordingly result is sent to single-chip microcomputer, through the processing of master controller, reach and allow the purpose of corresponding subscriber's extension station ring.
Adopted the door bell device of above-mentioned realization speech identifying function, because wherein with speech identifying function and the ingenious combination of doorbell control function, thereby overcome the existing defective of existing door bell and button system, have simultaneously the high characteristics such as intelligent, simple to operate, flexible, easy to use, the number that the user only needs voice suggestion to live, system can make corresponding subscriber's extension station ring automatically, thereby prompting has the visitor to arrive, not only simple in structure, and stable and reliable working performance, the scope of application is comparatively extensive, all brings great convenience for people's work and life.
