Embodiment
Further specify below in conjunction with accompanying drawing.
Shown in Figure 1 as theory diagram, the telephone set of this speech recognition controlled dialing comprises: part such as telephone set microcontroller (1), voice module (2), telephone interface circuit (3), telephone communicating circuit (4), power supply circuits (5), keyboard (6) and LCD display (7) is formed.Keyboard (6) and LCD display (7) connect the corresponding port of microcontroller (1) respectively, the interface circuit (3) of answering the call between microcontroller (1) and the telephone wire, the speaking circuit (4) of answering the call between telephone interface circuit (3) and the microcontroller (1), the serial port of microcontroller (1) connects a voice module (2), voice module (2) connects power supply circuits (5), voice module (2) contains speech chip (8), articulate large flash memory (9) on the speech chip (8), resident large capacity telephone number book and incoming call remove electric directory in this large flash memory (9).LCD display (7) adopts the lattice type LCD display, can show Word messages such as name, phrase.
Power supply circuits (5) sampling end connects an input test side of microcontroller (1), connect an electronic switch between the power end of voice module (2) and power supply circuits (5) output, microcontroller (1) is to start or cut out voice module (2) according to supply power voltage high or low, when microcontroller (1) detects the situation that does not have enough powered battery or external power supply, automatically close operation to voice module (2), switch to the operating state of power saving, guarantee the normal use of basic function; In case detect enough power supplies, promptly can start speech recognition work automatically.
Use voice dial-up function to need storaged voice phone directory in advance: the user first talks about the other side's name, miaow head in the telephone set speaking circuit (4) picks up the sound of name, and voice signal is sent to voice module (2), is stored by voice module (2), as template, the usefulness that contrasts during for speech recognition.This process also is referred to as training process.
During phonetic dialing, miaow head in the telephone set speaking circuit (4) picks up the sound of the said the other side's name of user, voice signal is sent to voice module (2), discern by voice module (2), and the telephone number that recognition result is promptly corresponding with name passback telephone set microcontroller (1), telephone set microcontroller (1) control telephone interface circuit (3) is connected the other side's phone, realizes conversation by telephone communicating circuit (4).
In the communication process, the user presses the calling record key in the lower keyboard (6), and after microcontroller (1) detected, the speech of will conversing was sent to voice module (2) and realizes the calling record function.
When the other side sent a telegram here, microcontroller (1) extracted the other side's telephone number, is sent to voice module (2), searches the name corresponding with number by voice module (3), and the recording of this name of playback, realized incoming call registration function.
Fig. 2 is the schematic diagram of embodiment HC1501 speech recognition controlled telephone set.Fig. 3 is the electrical schematic diagram of voice module part.Embodiment telephone set microcontroller adopts the HC1501 chip, voice module is selected JT82 telephone set dedicated voice identification module (being IC402) for use, adopt voice recognition chip JT302 in the voice module, flash memory adopts the SST39VF080 chip, and large flash memory SST39VF080 is articulated on the speech chip JT302 bus.Keyboard and LCD display connect the corresponding port of microcontroller HC1501 respectively, the interface circuit (3) of answering the call between microcontroller HC1501 and the telephone wire, the speaking circuit of answering the call between telephone interface circuit (3) and the microcontroller HC1501 (4).
Between telephone set microcontroller HC1501 and the voice module JT82 is master slave relation.HC1501 is a master controller, and JT82 is from module.The 3 line serial interface communication that communication interface between the two adopts MHS, SHS, SDATA to constitute.Telephone set powers on, HC1501 can detect cell voltage by the VBDET port earlier, as cell voltage＜3.3V, then can forbid voice module work, phonetic dialing, calling record, come senior disablers such as telegram function, and keep basic caller ID telephone function.
As cell voltage＞3.3V, then attempt setting up and communicate by letter by serial line interface and JT82 voice module, as the success of communicating by letter, then enable phonetic dialing, calling record, come the telegram function, and utilize the large flash memory SST39VF080 of JT82 to set up extra large capacity telephone number book, incoming call removes electric directory.As it is unsuccessful to communicate by letter, then reset after the JT82 module by the RESET holding wire, attempt setting up communication once more, as failure once more, show the JT82 module damage or do not exist, then forbid phonetic dialing, calling record, come the telegram function, set up the less yellow pages and the electrographic recording of making a return journey, still become the caller ID telephone of a telotism at the HC1501 chip internal.
Telephone interface circuit among Fig. 2 (3), telephone communicating circuit (4) and power supply circuits (5) repeat no more with traditional circuit.
The startup of voice module or to close be that power supply by control voice module JT82 is realized.Between the power end of voice module JT82 and power supply circuits (5) output, connect an electronic switch, HC1501 detects the height of cell voltage by the VBDET port, cell voltage＜3.3V then can forbid voice module work, cell voltage＞3.3V voice module operate as normal.Fig. 2 electronic switch adopts triode and peripheral Resistor-Capacitor Unit thereof to constitute.
HC1501 and JT82 share loudspeaker, miaow head and hands-free loudspeaker, the miaow head in the receiver, carry out the coupling of voice signal by electric capacity.Square speech is recorded down and is delivered on the telephone wire by HC1501 control miaow head during conversation; The sound of the name of when training, phonetic dialing, the sound of calling record then by JT82 by miaow head record.Dialing tone, telephone bell are sent by HC1501, and both sides' speech is sent by HC1501 control during conversation; And training process prompt tone, phonetic dialing prompt tone, incoming call registration sound, telephonograph playback sound are sent by JT82.
In the process of phone operation, special function keyboard can be carried out this training of voice call, telephonograph and playback function and the associated function that is provided with easily.The ability of dot matrix LCD display text then can be indicated the phone current state, points out next step operation, and it is easier to make the user operate.
