The utility model comprises a mike, a keyboard, a magnified circuit connected with the mike, and a filtration circuit connected with the magnified circuit. The utility model is characterized in that the filtration circuit comprises 3-8 electric filters with different acoustic frequency sections, an output of the filtration circuit is electrically connected with a control circuit, and the I/O interface of the control circuit is connected with the keyboard and an electronic switch.
Description
Affiliated field: the utility model relates to a kind of voice control multi-channel electronic switch, and it can be adapted to the voice control of various household electrical appliance.
Background technology: existing household electrical appliance are many to be used to control the various functions of household electrical appliance for control device of wireless is arranged, and controls bright, the colourity of channel, sound of televisor as the telepilot of televisor.Telepilot control wind direction in the air-conditioning, temperature or the like.But, but can not be convenient to use telepilot to the patient of trick activity inconvenience.Though present have the employing speech recognition system, because price height and complexity also do not spread to household electrical appliance.And simple voice control exists the low problem of discrimination.
Chinese patent discloses a kind of＜intercom acoustic control telephone transmitter 〉, its patent No. is 00254108.4, it is to realize that by intercom acoustic control telephone transmitter when signal import, mobile phone was launched signal.
Summary of the invention: the purpose of this utility model is that design is a kind of simply, price is low, the phonetic controller that phonetic recognization rate is high.
The purpose of this utility model is to realize like this, design a phonetic controller, it comprises, microphone, keyboard, the amplifying circuit that is electrically connected with microphone, the filtering circuit that is electrically connected with amplifying circuit, it is characterized in that: filtering circuit includes the wave filter of 3 to 8 different audio sections, and the output of filtering circuit is electrically connected with control circuit, is electrically connected with keyboard and electronic switch on the I/O mouth of control circuit.
Described control circuit can be the integrated circuit that has multi-channel a/d converter.
Described integrated circuit can be AT89S8535.
Described control circuit also can be the integrated circuit that has memory and have multi-channel a/d converter.
Described electronic switch can be a triple gate output integrated circuit.
The course of work of phonetic controller comprises initialization and two processes of voice control output of voice messaging:
1, the initialization of voice messaging, the initialization of voice messaging is that the voice through confirming are transformed into electric signal through microphone, at first select the signal of different audio frequencies by the multichannel filtering circuit, change multifrequency point numeral amount into by the control circuit that has multi-channel a/d converter and be stored in a certain address field of memory, described affirmation process is to finish after being carried out by the acknowledgement key on the keyboard; Memory can deposit the input of a plurality of different phonetic in, and deposits it in different memory address section, and these different memory address sections have determined different control circuit output;
2, voice control output, after the initialization acknowledgement key is finished, enter voice control output, after initialization finished in the voice of confirming, so long as import once more through the voice of confirming, control circuit compares with digital quantity in having memory digitized phonetic entry by different addresses, when unanimity, make electronic switch action of corresponding output terminal control, each electronic switch can be a button of existing household electrical appliance.
The utility model has the advantages that: because the utility model adopts the multichannel filtering circuit to extract the phonetic feature of different phonetic in system, deposit in the memory by the control circuit that has multi-channel a/d converter and with it, it can effectively remove noise effect that individual pronunciation difference and environment cause etc., therefore the phonetic recognization rate height improves the reliability of control system greatly.Simple in structure, adopting the control circuit have multi-channel a/d converter is that microprocessor carries out speech pattern recognition, and it is low to have a cost, can be adapted to various electrical equipment.This system can embed in the household electrical appliances such as air-conditioning, light fixture, realizes the voice control of household electrical appliances, thereby substitutes traditional telepilot.
The utility model is described in further detail for knot embodiment accompanying drawing below:
The utility model is described in further detail for knot embodiment accompanying drawing below:
Description of drawings: Fig. 1 is the utility model embodiment 1 schematic block circuit diagram;
Fig. 2 is the utility model embodiment 2 schematic block circuit diagram;
Among the figure, 1, microphone; 2, amplifying circuit; 3, multichannel filtering circuit; 4, the control circuit that has multi-channel a/d converter; 5, keyboard; 6, memory; 7, electronic switch.
Embodiment: as shown in Figure 1, Fig. 1 adopts the embodiment of AT89S8535 integrated circuit as control circuit.It comprises, microphone 1, amplifying circuit 2, multichannel filtering circuit 3, the control circuit 4, memory 6, keyboard 5, the electronic switch 7 that have multi-channel a/d converter are formed, microphone 1 can be selected the good microphone of range, the input of microphone 1 is after the amplifying circuit 2 of low distortion amplifies, be input to the input end of multichannel filtering circuit 3, multichannel filtering circuit 3 can be chosen 3 to 8 audio sections; Actual conditions can liken to select according to performance and price.The control circuit 4 that has multi-channel a/d converter can adopt the AT89S8535 integrated circuit, also can select the integrated circuit of other band A/D converter; On the I/O mouth of the integrated circuit of being with A/D converter, be connected with keyboard 5, on data bus, be electrically connected with memory, on the I/O mouth, be electrically connected with electronic switch, electronic switch 7 can be the button of existing household electrical appliance, by microphone 1 input one voice, when these voice had deposited memory 6 in, the control circuit 4 that has multi-channel a/d converter was through confirming; Can move by control one electronic switch, the control household electrical appliance are finished a certain function, establish the intensification or the cooling of transferring in the device as sky.As channel selection in the televisor etc.Certainly this is to realize by control circuit 4 programmings that have multi-channel a/d converter.
The utility model also can adopt promptly with the high capacity memory again with the control circuit of multi-channel a/d converter.As shown in Figure 2, its course of work is identical with Fig. 1.
