Abstract

PURPOSE:To improve the utilizing efficiency of lines, by stopping useless response, through the response interrupting operation with a push button signal from the user side, in an audio response system. CONSTITUTION:During the response period from a center system 10, a response step which enables to receive the interrupting request with a push button signal from the user is prepared. The center system receives the interrupting request when the audio signal during transmission enters no-sound period, and the transmission of audio signals afterward can be interrupted.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a response interruption method, specifically, a voice response system using a public telephone line, in which a response interruption operation by a single button g1-@ is performed by a user for 3Jt, and the line The system aims to improve the utilization efficiency of the system.

BACKGROUND OF THE INVENTION Today, when online services using subscriber telephone networks are in full swing, voice response systems using electronic computers have come to be used for a variety of purposes along with advances in voice synthesis technology.

FIG. 2 conceptually shows the procedure for using a general form of a conventional voice response system using a congregational communication line. In the voice response system using the congregation communication line, a user calls the center system 1 from the general subscriber line 4,
Having received a response from this RUNTA system 51, the user then transmits the necessary information by voice or by using the push-button signal or push-button signal attachment of the telephone 4. As a result, a response from the center system 1 is transmitted in the form of voice via the rope control device 1 and the switching network 3.

By the way, according to the above-mentioned conventional method, even if the user wants to interrupt the response during a response from the Ryunta system, the transmission format is one-way transmission due to the nature of the public viewing. I can't. Therefore, the user has to wait until the response is completed and the center system 111 is ready to receive information from the user, which has the following drawbacks.

If you do this, you will not be able to unnecessarily lengthen the response text, and if the user receives an unfavorable response, the usage efficiency will be poor and the service's time will be wasted. Then, i') it had nine various drawbacks.

The present invention has been made based on the above-mentioned circumstances, and improves the efficiency of system utilization by realizing a response procedure that allows accepting an interruption request from a user using a button signal during a voice response. The purpose is to provide an improved response interruption method.

Hereinafter, the present invention will be explained in detail using Figure #I3 and subsequent figures.

6011+, 60'l indicating the signals 0 Below, the operation of the present invention will be explained in detail.0 First, the operation of the schematic embodiment in Section 3- will be explained using the concept of the electrodynamic diagram 4. Under the control of the computer 11, the response information to the voice production device xxd is sent to the network control interface 1.
4. Information obtained from the user is sent to (9)-16 via the network control device 1s.

The farewell is received by the receiving device 11 via the network control interface 14, and then transferred to the control computer 11. In the control calculation 4!1111, the procedure shown in FIG.
, start the response operation.

The center system receives information #1 from the island and users,
Response #1 is output to the user. During this response period, during the silent section of the response sentence (a state in which there is no audio output carrier), the P8EL signal is obtained via the same 16 by the raw Ift and P8EL signals. The signal is supplied to the receiver 41 scissors 13 via the 1I4111J control interface 7 Aime 14. At this time, the receiver Mlik & 11 defines one of the signals and codes defined in the Bushmetan signal ° as an interruption code and outputs the information B. ) is detected.

In &44-, if the user does not transmit information B, the response from the center system is $1tj1→l) -+
After all 6 information has been output, an announcement is made to request the next information dormitory.

After receiving it, the user sends information #2 to the center system. The center system receives information #2 and outputs response #2. When the user requests the system to interrupt its response, press and hold until information B is accepted.

When the center system receives this information B during the silent period from responses #21 to #2b, it interrupts response #2 and sends response #3.
The center system connects to another service that outputs response #4.

The silent section in which the interruption information is accepted is set at a break in the text, at a position where the response text is not difficult for the user to understand, and at a time when the receiving circuit IJ can distinguish it. Figure 5 shows an example of setting the silent section NF. Below, while referring to the tining chart in Figure 7, #
Using FIG. 16, we will explain in detail the operation of the Sadashi example for receiving the interrupted 4I signal in a silent section.

First, the audio digital information obtained from the control computer 11 is supplied to the audio equipment via the line 604.
◇Audio generator 614 is converted to D/A and the signal is switched via line 101 as an audio carrier sL
A matching amplifier 61 is supplied to @signal switching section kl supplied to L.
1, is propagated to the network controller 15 via line 601.

With the signal switching sLi, the audio signal is also supplied to the receiving 4N circuit U via the matching amplifier ixx, but only when the audio carrier's output is low, the D/MU conversion output at the audio output device is switched to the line gos. Since the signal gate δ is set, no valid signal is supplied to the receiving station LJ. This is to prevent the receiving device L1 from recognizing t4 during the audio carrier output. If this continues to occur, on line 601, while the audio carrier is being output, the audio carrier and the Bushmetan signal will be mixed. In this state, when the audio digital information output from the control calculation *11 disappears, a wholesale silent interval will occur. When detected, the D/MU conversion output obtained from the audio generator is sent to the signal switching unit 1 via the twin CO#.
1. ζ In this case, the gate 611 is opened, and the bushmethane signal inputted via the twin-01 is supplied to the receiving device RI via the matching amplifier exa. In the receiving device U, the pushbutton signal is applied to the pushbutton signal discriminator 61j through an amplifier 625, a gate 6z4, and a filter s to convert the pushbutton signal into a desired digital value. The signal flowing through the gate 614 and the control 1 twin 10J is the control calculation I! It is used when stopping the reception of Bushmetan signal in ≠1 & 11, and #i is included in the present invention.
Not involved - 0 Therefore, m- here is omitted 0 Note that the buttons are digitized by the button signal discriminator 11, and the 9-button button signal is converted into a 4-bit code and a control signal via the signal line 〇1. It is separated into a tie signal and propagated to the control calculation 1111.

During the silent period, if the button signal does not arrive on the reception path Ll, the signal propagated on the line 0C becomes valid (ON) when the carrier reception is opened (ON). Carrier detection @ 611 output My friend, I am buried in an OFF state. Therefore, control calculation 11JJ is putu v:Lg
The interruption code detection by the tongue g14II is not performed, and the process moves on to the next audio output rotation.

As explained above, according to the present invention, a response procedure is provided that allows a user to accept a request for interruption using the Book Evo Meng message during the response period from the system, thereby improving the utilization efficiency of the p1 cycle. . In other words, the conventional service is based on the control procedures of the center system. However, by adopting the present invention, the user can reduce unfavorable responses and study the WIR, and the order of services can be adjusted according to the user's wishes. In addition, when building a center system, there is no need to configure the dormitory according to the maximum number of steps desired by all users, which increases the efficiency of system usage. improves.
