Description

Description: FIELD OF THE INVENTION The present invention relates to a voice response recognition apparatus of the present invention, and more particularly to a voice response recognition apparatus suitable for detecting an abnormality.

[Background of the Invention]

A voice response recognition device that inputs information such as a personal identification number by a PB signal or voice by using a telephone line and performs a service by voice response is widely used in bank balance inquiry services and the like. In this voice response recognition apparatus, an analog section that handles voice signals and a logic circuit section that controls each section coexist. Among them, the failure of the logic circuit section can be constantly monitored by responding to various commands, but the failure of the analog section such as the voice demodulator of the voice response device or the analog amplifier of the voice recognition device is in operation. It is difficult to find out. For this reason, for example, in the prior art disclosed in Japanese Patent Laid-Open No. 58-50599, the voice output is branched and input to the voice recognition unit to monitor the voice output. But,
This prior art does not consider the processing after the abnormality is found in the voice output.

[Object of the Invention]

It is an object of the present invention to provide a voice response recognition device which, when an abnormal fault is detected during operation, automatically processes the abnormality and makes a normal voice response.

[Outline of Invention]

In order to achieve the above-mentioned object, in the present invention, any one of a plurality of voice output units is selected, and the selected voice output is input to a selected one of a plurality of voice input units (voice recognition units), Connect the voice output unit and voice input unit whose normality is confirmed to the user line.

Example of Invention

 An embodiment of the present invention will be described below with reference to the drawings.

The figure is a block diagram of a voice response recognition apparatus. In the figure, a telephone 1 used by a user is connected to a trunk section 2 including an incoming call detection circuit. The trunk unit 2 and the voice demodulation unit 8 serving as a voice output unit are connected via a line connection relay contact 3 and a voice output relay contact 4, and any _{one of} a plurality of voice demodulation units (DEM _{1 to} DEM _n ) 8 Is selected by the output selection relay contact 6. The trunk section 2, the PB signal receiving section 9 and the voice recognizing section 10 are connected via the line connection relay contact 3 and the voice input relay contact 5 and a plurality of PB signal receiving sections (PB
One of the R _{1 to} PBR _n ) 9 and the voice recognition section (SRU _{1 to} SRU _n ) 10 is selected by the input section selection relay contact 7. Each voice demodulator 8 is connected to a voice editor 11 having a voice memory 12, each PB signal receiver 9 and each voice recognizer 10 is connected to a controller 13, and a main controller connected to a host computer (not shown). 14 is a voice editing unit 11 and a control unit
It is designed to control 13.

With this configuration, when the telephone set 1 arrives at the trunk section 2 of the voice response recognition device through the public line network, the main control unit 14 knows the incoming call by the incoming call detection function in the trunk circuit. At this time, the main controller 14 confirms the normality of the device as follows. First, the selection relay contacts 6 or 7 of the output unit and the input unit are connected to the vacant voice demodulation unit 8 and voice recognition unit 10, respectively, the line connection relay contact 3 is opened, and the voice output relay contact 4 and the voice input relay are opened. Contact 5
Close together. Next, the test voice of the PB signal receiver 9 and the voice recognition unit 10 is folded back along this route,
The control unit 13 checks the response result. If normal, the line connection relay contact 3 is connected to enter the service to the telephone 1 via the user line. If a normal response is not obtained, the relay contact 6 or 7 is switched and moved to another voice demodulation unit 8 or voice recognition unit 10 or the like, and the above operation is continued until a normal response is obtained.

As described above, according to the present embodiment, it is possible to automatically perform the processing of confirming the normality of the device before connecting the user's line and not using the part when a failure is detected. is there.

〔The invention's effect〕

According to the present invention, a failure is automatically detected during operation and its processing is performed. Therefore, maintenance work can be omitted, failure processing can be performed early, and the user is less annoyed. effective.
