Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a voice response device intended for subscriber telephone networks.

As shown in FIG. 1, a conventional voice response device 10 includes a first line trunk 4, a second line trunk 5, a voice recognition device 6, a multifrequency signal receiving device 7, a voice output device 8, and a voice response device. It is composed of a control device 9. Each of the plurality of line trunks 4 and 5 has a separate telephone number. When a telephone subscriber desiring reception input calls the voice response device 10 from the telephone 1 using the dial number designated by the trunk, the device 10 is connected to the trunk 4 via devices 6, 9 and 8 from the trunk 4. Ru. As a result, the telephone subscriber uses telephone 1 to
In addition to receiving services by voice from 0, necessary inputs from the push-button dial telephone 2 can be made using push-buttons. However, the input from the rotary dial telephone 1 cannot be recognized by the multifrequency signal receiving device 7, and similarly the input from the pressed lead dial telephone 2 cannot be recognized by the voice recognition device. Depending on whether the subscriber uses rotary dial telephones, separate groups of trunks 4 and 5 must be provided. For this reason, when a telephone subscriber makes a call to the voice response device 10, the telephone number that responds must be determined and used depending on the subscriber's telephone model, which is a very burdensome burden on the user. Furthermore, when making a call from the voice response device 10 side, it is difficult to predict what type of telephone 1 or 2 the called party is using. If a call is made from a trunk equipped with a multi-frequency signal receiving device 9 in anticipation, if the subscriber uses the rotary dial telephone 1, the call will not be possible. On the other hand, if a subscriber using the push-button dial telephone 2 makes a call from the trunk 4 equipped with the voice recognition device 6, an inconvenience arises in that the call cannot be made by push-button input, but input must be made by voice.

An object of the present invention is to classify a receiving trunk that needs to be classified by an input receiving device in a voice response device using a telephone line and equipped with a voice recognition device and a multi-frequency signal receiving device as an input receiving function from a telephone subscriber. To provide a voice response device in which a voice recognition device or a multi-frequency signal receiving device can be applied according to the function of a telephone used by the subscriber, and the device can be used from the subscriber side without having to do so. There is a particular thing.

The device of the present invention includes a line trunk that receives a signal from a telephone, a multifrequency signal receiving device that generates a corresponding digital signal when the signal from the line trunk is a multifrequency signal, and a multifrequency signal receiving device that generates a corresponding digital signal when the signal from the line trunk is a multifrequency signal. a voice recognition device that receives a signal together with the multifrequency signal receiving device and generates a corresponding digital signal when the signal is a voice signal; and the voice recognition device in response to the digital signal from the multifrequency signal receiving device. a voice response control device that stops receiving control instructions for the multi-frequency signal receiving device in response to a digital signal from the voice recognition device; and a voice output device for sending a response voice signal to the line trunk.

Next, the present invention will be explained in detail with reference to the drawings. Referring to FIG. 2, the first embodiment of the present invention includes a first line trunk 4, a second line trunk 5, a hybrid coil 10, a buffer amplifier 11, a voice recognition device 6, and a multi-frequency signal receiving device. 7, voice response control device 9, and voice output device 8
It consists of The audio output device 8 shown in FIG. 4 includes an upper connection addition mechanism 81, a memory 82, a microprocessor 83, an audio response control device 84 consisting of a minicomputer, an audio data memory 85 for storing audio data, and a digital audio data storage device. It consists of an audio reproduction unit 86 that reproduces the audio into an analog signal. The voice recognition device 6 shown in FIG. A recognition unit 63 consisting of a microprocessor that analyzes and calculates the digital signal converted by the conversion unit 61, and a program storage unit 6 that stores a group of instructions for controlling the operation of this unit 63.
4, a control unit 65 for controlling the operation of the entire recognition device, and an interface section 66 for the upper controller 9, which has a memory 661 for storing function patterns. The multi-frequency signal receiving device 7 outputs digital bits and timing signals in response to receiving the multi-frequency signal.

Next, a first embodiment of the present invention will be described in detail.
Only voice signals are sent from the rotary dial telephone 1 to the voice response device 12. This voice signal is provided to a voice recognition device 6 and a multi-frequency signal receiving device 8 via a telephone switched network 3, a first line trunk 4, a hybrid coil 10, and a buffer amplifier 11. These devices 6 and 7 are voice response devices 9
The audio signal is received according to an instruction from the user. The received voice signal is converted into a digital signal by the AD conversion unit 61 in the device 9, and then analyzed by the recognition unit 63 based on the control signal from the unit 64. to notify that the correct audio signal has been received. However, since the audio signal is not a predetermined frequency signal in the multifrequency signal receiving device 7, neither digital bits nor timing signals are output. The control device 9, which has received the notification that the correct voice signal has been received, disconnects the control of the device 7, and the subsequent reception operation is performed only by the voice recognition device 6. In the above explanation, the voice signal from the rotary dial telephone 1 has been explained, but when a multi-frequency signal from the pressed lead dial telephone 2 is given, the device 6
and 7 receive multifrequency signals. In this case, the recognition unit 63 of the voice recognition device 6 analyzes and processes the voice signal, so it is not a correct voice signal, so the voice response control device 6
will not be notified. On the other hand, since the multi-frequency signal receiving device 7 has received the correct signal, a digital bit and a timing signal are outputted and the voice response control device 9 is notified. This device 9 is device 6 or 7
An instruction signal is output to the audio output device 8 in response to the notification from the voice output device 8. The voice output device 8 generates and outputs a response voice in response to this instruction signal. That is,
The voice data stored in the memory 85 of the device 8 is edited by the microprocessor 83, sent to the line designated by the voice response control device 84, and the digital signal is converted into an analog response voice signal by the reproduction unit 86 and output. Ru.

Next, a second embodiment of the present invention will be described in detail with reference to FIG. The second embodiment of the present invention includes a first line trunk 4, a second line trunk 5, a voice recognition device, a multifrequency signal receiving device 7, a voice output device 8, a voice response control device 9, a hybrid coil 10, Buffer amplifier 11 and multiplexer 1
3 and 14. The configurations of the devices 6, 7, and 8 are the same as those used in the first embodiment. In this second embodiment, the multiplexer added to the first embodiment is connected to the device 7 whose control is disconnected by the device 9 in response to a notification from the device 6 or 7 in the operation of the first embodiment described above. or 6 to be used for other line services. For this reason, a line switching operation is performed.

In the present invention, in a voice response device using a telephone line network equipped with a voice recognition device and a multi-frequency signal receiving device in order to receive input from a telephone subscriber, the receiving line trunk that needs to be separated by the input receiving device is divided. This has the advantage that the voice response device can be used as a voice recognition device or a multi-frequency signal receiving device depending on the function of the telephone used by the subscriber.
