JPS61117959A - Telephone set with voice synthetsis calling function - Google Patents

Abstract

PURPOSE:To enhance surely a calling function even when a telephone set is used in a surrounding where sound is not listened to clearly by generating a bell tone (one ringer tone) and a voice synthesis tone. CONSTITUTION:A call signal from a telephone line is normally an intermission signal and since a tone ringer circuit 2 is actuated synchronously with the call signal, the circuit 2 does not issue ringing while no call signal exists. On the other hand, since a detection circuit 3 outputs a prescribed voltage only during the incoming of the call signal, when the call signal comes to a pause, the output voltage of the detection circuit 3 changes from a high level to a low level. A voice synthesis circuit 4 is started when the output voltage of the detection circuit 3 changes from a high level to a low level, and generates a voice synthesis signal over a prescribed time. The sound synthesis signal and the output signal of the tone ringer circuit 2 are converted into an audible tone through a sounding body 5.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a telephone that uses synthesized voice as a calling means other than a bell sound.

(Prior Art) Conventional telephones that have used synthesized speech sounds as a means of calling have used synthesized speech sounds in place of the bell tone.

(Problems to be Solved by the Invention) Therefore, when used in a noisy place or a place where the level of human voice is high, the ring tone tends to be audibly inconspicuous. 4 Gorges 〒→-1 The purpose of the present invention is to eliminate the above-mentioned drawbacks by ringing the conventional bell sound and generating a voice synthesized sound when the bell sound is paused, thereby adding value as an accessory to the telephone and making it reliable. To provide a telephone with a voice synthesis calling function configured to achieve a calling function.

(Means for Solving the Problems) A telephone with a voice synthesis calling function according to the present invention includes a detection circuit, a tone ringer circuit, a voice synthesis circuit, and a sound generating means.

The detection circuit is for detecting a pause in the ringing signal from the telephone line.

The tone ringer circuit is for generating a pseudo-bell tone in synchronization with a ringing signal.

The audio synthesis circuit is for synthesizing specific audio signals recorded in advance.

The sound generating means is for reproducing the voice signal from the voice synthesis circuit when the calling signal is paused.

(Example) Next, an example of the present invention will be described with reference to the drawings.

Referring to FIG. 1, an embodiment of the present invention includes a terminal 1 connected to a telephone line, a tone ringer circuit 2, a detection circuit 3 for detecting a pause in a ringing signal, a speech synthesis circuit 4, and the tone ringer circuit 2. a sounding body (
For example, it consists of a speaker) 5.

A ringing signal from a telephone line is usually an intermittent signal; for example, a signal arrives for one second, then there is no signal for two seconds, and the above-mentioned state is repeated until the line is acquired. The tone ringer circuit 2 operates in synchronization with the ringing signal, similar to the conventional one, for example, in which the circuit operates and oscillates depending on the ringing signal power, and does not ring during the period of the ringing signal. The circuit 3 is a circuit that outputs a constant voltage while a calling signal is coming, and does not output voltage during a period when there is no calling signal.

A well-known method for realizing such a circuit is, for example, to obtain an output by rectifying and smoothing a calling signal (usually an alternating current signal).

Therefore, when the ringing signal starts to pause, the detection circuit 3
The output voltage of will change from high level to low level.

The voice synthesis circuit 4 is activated when the output voltage of the detection circuit 3 changes from a high level to a low level, and generates a voice synthesis signal for a certain period of time (within 2 seconds in this embodiment).

Both the voice synthesis signal and the output signal of the tone ringer circuit 2 are converted into audible sounds through the sounding body 5.

The actual sequence of voice synthesized sounds mentioned above are voices intended for calling, such as ``Telephone ga Kakata-First'' or ``Telephone call'', and are commonly used to express well-known celebrities or manga protagonists. In some cases, a synthesized voice is used.

(Effects of the Invention) As explained above, the present invention reliably exhibits the calling function even when used in an environment where voices are not noticeable by generating a conventional bell sound (tone ringer sound) and a voice synthesized sound. There is an effect that it can be done.
