For solving above-mentioned task, the scheme that the utility model is taked is with devices of dialing the number automatically with voice of formation such as speech recognition system (contain in this system be used for the RAM of stored sound feature, deposit the phonetic feature sample with it), interface circuit, repertory dialler memory, dial-up circuit, keyboards.

Fig. 1 is the block diagram of such scheme.Before the use, at first the voice that will discern (as callee's name) deposit among the RAM of speech recognition system one by one by microphone and keyboard ［ 5 ］ in advance, and corresponding with it telephone number also deposits in the repertory dialler memory ［ 3 ］ one by one by keyboard ［ 5 ］.During use, user's off-hook and pronunciation, speech recognition circuit ［ 1 ］ will compare the characteristic quantity of the voice of microphone input and the characteristic quantity that pre-deposits the voice among the RAM one by one, run into (the allowing certain deviation) of phonetic feature unanimity, speech recognition circuit ［ 1 ］ will be exported the code of this unit among the RAM, after interface circuit ［ 2 ］ decoding, choose memory cell corresponding in the repertory dialler memory ［ 3 ］, by dial-up circuit ［ 4 ］ dial-out telephone number wherein.Simultaneously, can demonstrate telephone number by LED or LCD decoder, display ［ 6 ］.

This device both can be contained in the existing memory-type telephone set, with the shared keyboard of this machine, microphone, repertory dialler memory and dial-up circuit, power supply circuits etc., also can be separately as an adapter of telephone set, link to each other with existing wired or wireless telephone set, make it have voice control automatic dialing.

In above-mentioned several schemes, if the output of interface circuit directly is connected on the digit dialling key of telephone keyboard, in speech recognition system, deposit the pronunciation consistent in keyboard digital, also can constitute telephone set with the digital speech dial-in direct, its feature is to replace manual button to dial one by one with voice, need not pre-deposit telephone number.

In order to improve the discrimination of voice system, can in interface circuit, add AND, with one two syllable or polysyllabic voice, be divided into two or more single syllable and discern.Because the discrimination that speech recognition system will be compared multisyllable, continuous pronunciation to the discrimination of single syllable, clipped is much higher.Equally, in order to reduce the error code rate of phonetic dial device, can in interface circuit, add twice checking circuit.When the user makes a phone call, repeat twice of same pronunciation.

Compared with prior art, the utlity model has following advantage;

1. need not remember or search callee's telephone number, as long as remember name;

2. for car-mount radio telephone, safe in utilization during driving;

3. easy to use to the disabled person;

4. night, easy to use when not having illumination;

5. it is easy to use both hands to be taken the people that can't dial;

6. it is convenient, rapidly and have one's own knack to be used for first aid and police emergency call, just may put through first-aid station or public security bureau automatically as victim's emergency sound.

Fig. 2 is the electrical schematic diagram of an embodiment of the present utility model.

The characteristics of Fig. 2 scheme are that speech recognition circuit ［ 1 ］ is made of monolithic speech recognition integrated circuit T6658A, RAM adopts UM6116, interface circuit ［ 2 ］, by CMOS integrated circuit 4556,4028,4081,4066 compositions such as grade, they are contained in the memory-type telephone set machine popular on the market, with the shared keyboard KB of former machine, microphone, repertory dialler memory ［ 3 ］ and dial-up circuit ［ 4 ］ (WE9148 finishes by a slice integrated circuit), (the speaking circuit in the original call machine such as power supply circuits and casing, do not omit among ringing circuit Fig. 2 and to draw), directly control the storage key of former machine by interface circuit.Except that increasing the voice automatic dialing, still keep the repertoire of former machine.

This machine course of work is as follows: if with the K closure, T6658A is in enrollment mode, this moment available keyboard Ky and cooperate the voice that pronunciation will typing to deposit RAM in.The telephone number that will deposit in is then keyed in repertory dialler memory WE9148 with keyboard KB.The number that deposits in is corresponding with the voice that deposit RAM in, disconnects K then.When making a phone call, user's off-hook and pronunciation, the voice that T6658A will send microphone here compare with the voice that pre-deposit RAM, produce recognition result, be that BLK2, BLk1, WD4, WD3, WD2, WD1 will export one group of code and decipher through interface circuit, choose keyboard KB to go up corresponding storage key, it is connected, the DP pin of integrated circuit WE9148 (during pulse dialing) or T pin (during dual-tone dialing) will be exported telephone number corresponding.
