Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a voice synthesizer in a telephone set, and allows the telephone set to generate electrically synthesized sound by giving the characteristic amount of sound as an electrical signal from the telephone set or the central office side. This is related to the telephone system.

The functions of conventional telephones were limited to amplification of voice signals and generation of dial signals, so they had the following drawbacks when attempting to provide voice response services for subscribers and from central offices. .

(1) Confirmation of dial operation In a rotary dial, confirmation of the dial number is performed visually by the operator.

In addition, with push-button dials, it can be confirmed that the dial signal is being sent by the signal tone corresponding to the button, but the number cannot be confirmed by this without relying on the operator's visual sense. No. (2) Confidential voice function for sending calls When you are using a telephone to talk to the other party, you have to put the receiver to your ear to listen to the other party's incoming signal, so there is no risk that someone other than the person using the telephone will hear the contents of the call. However, when transmitting a message, information can only be transmitted to the other party by the person speaking, so there is a drawback that confidentiality cannot be maintained.

(3) Voice response service In voice response services using telephones, the voice synthesizer is currently located at the center, so in order to simultaneously send different voice signals to many terminals in real time, it is necessary to A synthesizer will be required.

The present invention was made in view of the above-mentioned circumstances, and by providing a voice synthesizer in the telephone, it is possible to confirm the number by voice when dialing, thereby preventing incorrect dialing. By transmitting voice to the other party, the telephone has a confidential function for transmitting calls, and furthermore, in voice response services using telephones, it is intended to simplify the voice response device at the center.

The drawings will be explained in detail below. The figure shows a block diagram of an embodiment of the present invention.

In the figure, a push button 1, a push button signal oscillator 2, an amplification and side sound protection circuit 3, a transmitter 4, a receiver 5
etc. are functions provided in conventional push-button telephones, but the present invention adds a voice synthesizer 6 to these functions,
This is characterized in that the switch groups T to 11 are used by appropriately switching the switch groups T to 11. Since the configuration of the speech synthesizer 6 itself is well known, its details will be omitted, but it can be configured with, for example, one chip of IC. Note that 12 is the telephone office side. Next, in this embodiment, operations corresponding to three functions targeted by the present invention, namely, confirmation of dial operation, secret call function, and voice response service will be explained in order.

Confirm dial operation In this case, switches 7, 8, and 10 are turned on.

When pushbutton 1 is pressed, pushbutton signal oscillator 2
is driven, and a PB signal corresponding to the pressed push button is sent to the telephone office 12 side. At the same time, the speech synthesizer 6
is also driven to synthesize an audio signal indicative of the push button pressed, which is transmitted to the receiver 5 through the amplification and side sound circuit 3.
The push button you pressed can be confirmed by voice. Confidential transmission function In this case, switches 7 and 11 are turned on.

By pressing the push button 1, the voice synthesizer 6 is driven to synthesize the voice signal corresponding to the push button, and this voice signal is heard from the receiver 5 through the amplification and side sound protection circuit 3, and is also heard from the telephone station 12 side. The message is also sent and communicated to the other party. In other words, the user can convey the necessary information to the other party without making a sound. Voice response service from the station In this case, switch 9 is turned on.

The voice synthesizer 6 is driven by the signal sent from the telephone office 12, and the resulting voice signal passes through the amplification and side sound protection circuit 3 and is sent out from the receiver 5. In other words, the voice response service provided by the station is heard from the handset 5. In the above example, a case has been described in which a voice synthesizer is added to a conventional push-button type telephone, but as an example of further development, it is possible to add a PB signal oscillation function to the illustrated voice synthesizer. .

Since the PB signal is a signal obtained by synthesizing two frequencies, and the speech synthesizer is a kind of multi-frequency oscillator, this is fully possible. You can also add memory to the voice synthesizer and input parameters to the synthesizer corresponding to the voice you want to send to the other party using the push button, or store a predetermined voice, such as a call to a related organization in an emergency, in the ROM. It is conceivable to send the information to the central office side as necessary. As described above, according to the present invention, by providing a voice synthesizer in a part of the telephone circuit, dialing operations can be confirmed by voice, thereby reducing errors in dialing operations.

Furthermore, by inputting parameters necessary for voice synthesis from the dial, voice can be electrically synthesized and sent to the other party. This allows the user to convey the necessary information to the other party without making a sound, ensuring confidentiality during transmission. Additionally, adding a memory to the speech synthesizer so that it can synthesize speech determined as necessary may be useful in cases such as emergency communications. Furthermore, by sending the signals necessary for voice response from the station and driving the synthesizer within the telephone, the configuration of the voice response device placed at the station or center can be simplified.

Claims (1)

[Claims] 1. A telephone is equipped with a voice synthesizer and a switch that connects the voice synthesizer to a dial transmitter, a handset, and a line as appropriate, and by connecting the dial transmitter and the handset via the voice synthesizer, a dial signal can be generated. By converting the signal into voice and outputting it from the handset, and connecting the dial transmitter and the line via a voice synthesizer, a voice signal corresponding to the dial operation is sent to the line, and the line and handset are connected to the voice synthesizer. A telephone system characterized by outputting a voice response service provided from the central office side from the handset by connecting through the handset.
