Abstract

The present invention relates to a speech dialing method and a device without using a power supply. When a user dials, the speech dialing device emits a speech signal for the user to confirm whether a dialing number is correct or not; after the user confirms, the speech dialing device dials the number dialed by the user out in telecommunication signals. Thus, the present invention can avoid the defect that the traditional telephone dialer sends the dialing number out in the telecommunication signals after dialing the dialing number out every time so that the user does not efficiently master the dialing condition and the correctness. In addition, the dialing device of the present invention can make the dialing device transmit by clear speech signals for the user to confirm when the dialing device dials without needing an extra power supply.

Description

A kind of voice dial-up method and device of exempting from power supply

The invention relates to a kind of voice dial-up method and device of exempting from power supply, refer to especially a kind of user dial confirm after, just the button number is delivered in the telecommunication bureau, more can grasp dialing situation and correctness with convenient user.

According to conventional telephone set, no matter be to adopt dial-type or button complex frequency type, its dial-up program is roughly as follows, at first, after the user picks up phone device receiver, this telephone set has then been set up circuit with the exchange line of telecommunication bureau and has been linked switch, therefore when every group of digital keys of user, then the dialer of this telephone set will have pulse signal or two between frequency multiplexed signal directly export on telecommunication bureau's exchange line, for example: export with pulse signal, digital identical (dial 5 numerical key as the user, then will have 5 pulse signals to produce and output) that the pulse signal number of its output will be dialled with the user; Behind the complete FD finished dialing of person to be used, the signal that previous button is produced also all is sent in the telecommunication bureau, and so, the user can't confirm whether correct it dials the number, should transfer to signal to send out, this kind phenomenon for blind person or generally use for the people of telephone set in bad visibility, all will cause great inconvenience, on the other hand, when the user dialled mistake, it also must redial again, was the effect that does not meet practicality really.

In addition, no matter the conventional telephone set Dialing Method is to adopt the dial-type or the dialer of button complex frequency type, all cooperate following two kinds of voice devices, so these two kinds of devices have been found some problems and the puzzlement that causes the user to use:

1. voice signal is and the device of exporting simultaneously by key output signal: promptly when the user presses a certain button, to have pulse signal or dual-tone complex frequency signal and voice signal exports simultaneously, therefore will cause the current circuit of setting up between telephone set and the telecommunication bureau to have interrupted phenomenon to produce, as when pulse signal during in disconnected state, can't produce current circuit, also there is not electric current can supply the voice signal utilization of output, therefore the quality of this voice signal output will be very bad, for solving above-mentioned difficulties, then this telephone set must dispose a power supply that uses for sound circuit specially in addition again, so will not meet economic benefit.

2. voice signal lies in the device of just exporting after the button output, be digital keys that the user dials all with after pulse signal or the output of dual-tone complex frequency signal, the digital speech of user institute button is just exported and sent to this voice signal, at this moment, though the user can distinguish the telephone number correctness that it is dialled, so the signal because of this dial-out all is sent to telecommunication bureau, if when user's this moment finds that its dialing is wrong, then must dial again, this is for not meeting the practice of benefit again.

Because above-mentioned shortcoming, the inventor concentrates on studies specially and to cooperate scientific principle to propose a design, design implementation with practice all good and effectively improve the present invention of above-mentioned shortcoming.

Therefore, main purpose of the present invention, be and addressed the above problem, and provide a kind of voice dial-up method of innovation, when the dialing operation procedure, it can utilize voice functions and can reach dialing correctly in the time of dialing, and after FD finished dialing, the user does the affirmation of a number when errorless, this telephone set just is sent to telecommunication bureau with the keying signal that previous user dialled, in addition, and by this phonetic function, the user, can revise or cancellation this dialing and do not need to dial again more in addition if find the dialing mistake immediately in dialing time; Therefore the situation in the time of so can convenient user more grasping dialing and the correctness of institute's dial-up thereof, are used for blind person or when the bad visibility for the user of telephone set, are really one to have the effect of practicality.

Another purpose system of the present invention provides a kind of power source special that do not need to supply in addition, can produce voice signal output clearly, and reach the effect with power saving so that this has phonetic dial device when dialing.

The present invention is further described for following conjunction with figs. illustrated embodiment:
