Abstract

The utility model discloses a voice-controlling telephone number automatic dialing device, which is used on any telephone (double-tone multi-frequency telephone) and is controlled by callers' voice. The utility model adds an electro-acoustic assembly on the output end of a dialing circuit of a voice automatic dialing device. The utility model can dial the telephone number through a microphone of a common telephone, non-electrical connection is adopted between the utility model and the telephone, and thus, the utility model can be made into a telephone number memory notebook which can be carried about. When telephoning, the caller only call the name of a person who answers the telephone, and the utility model can conveniently make the telephone which is used by the caller dial the telephone number of the person, which is convenient in use.

Description

Voice-controlling telephone number automatic dialing device

The utility model relates to a kind of voice-operated device of dialing the number automatically with the telephoner.Especially the voice-operated phone number dial device of forming by speech recognition system, keyboard, telephone number memory device, dial-up circuit etc.

China's utility model patent--the voice-operated telephone automatic dialing unit (patent No.: 92226812) provide a kind of, the voice-operated telephone number auto-dial unit that dial-up circuit, display circuit are formed by speech recognition system, control circuit, keyboard, telephone number memory device.The telephoner is in advance with telephone number, and voice (as listener's name) deposit this device in.When making a phone call, as long as tell listener's name, telephone set will be transferred to its telephone number automatically.Like this, the telephoner just need not remember or search listener's telephone number, as long as remember the name of he (she).Because this speech recognition system, can only discern nominator's pronunciation, and this device and telephone set or telephone wire must be electrically connected, this has just limited the scope of application of this device, change a telephone set (this machine does not deposit telephone number and voice in) as the user, he (she) just can't use this function of phonetic dialing.

Task of the present invention provides a kind of voice-operated phone number dial device, it can be non-electric-connecting with any dual-tone multifrequency rotary phone machine, it can make the telephone number memory of carrying, keep telephone number and corresponding name (sound) in advance, when making a phone call, the user is as long as aim at dialer someone name (voice of this name have been logged in this dialer), and this dialer just can make any telephone set (dual-tone multifrequency rotary phone machine) transfer to this people's telephone number.

For solving above-mentioned task, the solution that the present invention takes is; Double-audio signal output at dial-up circuit inserts an audio frequency amplifier, and the output of this amplifier connects an electroacoustic component (as loud speaker) again.

During use, user's off-hook is aimed at the microphone of telephone set with the electroacoustic component of dialer, pronunciation then, and dialer is selected corresponding telephone number and is made dial-up circuit send the telephone number that double-audio signal is formed.This double-audio signal amplifies through audio frequency amplifier, drives the electro-acoustic element sounding, and this sign indicating number passes on the telephone wire through phone transmitter and voice amplifier again, the telephone number of so just having transferred to this user to dial.

Owing to adopted the electroacoustic assembly that links to each other with the dialing circuit, dialer separated with telephone set, and can make any dual tone phone extract telephone number by acoustical signal.So just enlarged the scope of application of voice dialling functions.On the other hand, this dialer can make the portable pocket articles for use as electronic notebook, or simply dialer is made in the electronic notebook, when making a phone call, uses it than using the ordinary electronic notepad to make things convenient for manyly.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is the schematic diagram of an embodiment of the present utility model.

Fig. 2 is a kind of external form figure of the utility model embodiment.

In schematic diagram shown in Figure 1, microphone M1 links to each other with speech recognition circuit 1, and the voice that will record by it deposit among the RAM that links to each other with speech recognition circuit 1.Interface circuit 2 is connected with speech recognition circuit 1, keyboard 5, telephone number storage dialing 4, and its effect is to translate the required code of each part mentioned above, pulse signal and control level.At electroacoustic assembly of double-audio signal output termination of dialing circuit 4, this assembly is made up of resistance R 1, transistor N1 and loud speaker S1.One of R1 terminates to the double-tone frequency dialing output (13 pin) of WE9148 referring to Chinese utility model patent " the automatic dialing device of voice-operated the phone " (patent No.: Fig. 2 92226812.6).Its course of work is as follows: before the use, at first the voice that will discern (as listener's name) deposit among the RAM of speech recognition system one by one by keyboard 5 and microphone 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 start, the electroacoustic component of dialer is aimed at the microphone and the pronunciation of telephone set, speech recognition system 1 will compare the phonetic feature amount of microphone input and the phonetic feature that pre-deposits 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 decodings, choose memory cell corresponding in the repertory dialler memory 3, by dialing circuit WE9148 outputting dual tone multi-frequency tone signal, amplify through transistor N1, drive electroacoustic component S1, electroacoustic component (loud speaker, Miniature acoustics device or piezoelectric buzzer etc.) acoustical signal that converts to imports the microphone of ordinary telephone set into, and audio frequency amplifier amplifies and passes on the telephone wire in telephone set, just telephone number can be extracted.If dialing circuit band display circuit, display 6 will demonstrate this telephone number.

Claims

A kind of voice-operated telephone number repertory dialer of being made up of speech recognition circuit, keyboard, repertory dialler memory, dialing circuit, interface circuit, display, shell, power supply of usefulness is characterized in that this dialer has in addition:

An audio frequency amplifier, its input links to each other with the double-audio signal output of dialing circuit 4, and its output links to each other with electricity-acoustic device, and double-tone frequency electrical signal conversion is become double-tone acoustical signal frequently.
