(57) [Summary] This bulletin contains application data before electronic filing, so abstract data is not recorded.

Description

[Detailed description of the invention] [Field of application of the invention] The present invention relates to a call recording device for a voice response device.

[Background of the invention]

For example, Hitachi Review VOL, 63. Nα12 (1981)
“Hitachi voice response device “HIVORS series””
As described in the paper titled ``Voice response devices are becoming popular.

This voice response device generally receives input data (
It has a call recording device that records push button FB signals, voice) and output data (voice) from the system.

The secondary storage device used in conventional call recording devices is an analog magnetic tape, which has the disadvantage that previously recorded content cannot be played back during recording.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a call recording device that can perform recording and playback at the same time.

[Summary of the invention]

In order to achieve the above object, the call recording device of the present invention uses a magnetic tape device as a secondary storage device instead of a conventional magnetic tape device.
For example, use a device that allows random access, such as a magnetic disk device. In order to reduce the storage capacity, analog signals are digitized and audio is compressed. At this time, if the push button signal is audio compressed, the reproduction will be incomplete, so the push button signal is not audio compressed. Therefore, since the voice and push button signals are converted into different digital information, the information is stored in separate files.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

The figure is a block configuration diagram of a call recording device, in which 1 is a voice response device, 2 is a telephone exchange network, 3 is a telephone terminal that transmits and receives data to and from the voice response device, 31 is a voice reproducing device, and 32 is a push button signal reproduction device. 20 is a call recording device.

In a voice response system in which the voice response device 1 receives push button data from the terminal 3 and notifies the terminal by voice, the content of the conversation between the system and the terminal is recorded and the content is recorded as necessary. The device for playing back is a call recording device.

The call recording device 20 compresses and digitizes the voice notified from the voice response device 1 via the voice compression device 24, and stores the voice data in a randomly accessible secondary storage device 22 under program control of the control processor 21. Store it in a file for use.

In addition, the push button signal from the telephone terminal 3 is converted into an A/D
The signal is digitized via the converter 23 and stored in a push button signal file in the secondary storage device 22 under program control.

As mentioned above, the audio data and the push button signal are subjected to different A/D conversions and stored as separate files in the secondary storage device 2.
2.

During playback, audio data and push button signal data are read out from the secondary storage device 22 under program control of the control processor 21, and the audio data is read out from the audio compression device 2.
5, the signal is reproduced into an analog signal, and outputted as audio by the audio reproducer 31.

Further, the push button signal data is converted into numbers via the push button signal regenerator 32 and printed out to a printer.

〔Effect of the invention〕

According to the present invention, while recording conversation data between the system and the terminal, it is possible to play back data that has already been recorded.

Furthermore, by separately storing the voice and the push button signal, the voice can be stored as voice compressed data, and the storage capacity can be reduced.

Claims (1)

[Claims] In a call recording device that is connected to a system where input data from a terminal is a push button signal and output data from the system is output as an audio signal, it records conversation data between the terminal and the system in chronological order. The button signals are collected separately, the input audio is audio compressed and digitized, the push button signal is digitized without audio compression, and these two types of digitized data are stored in two types of randomly accessible storage devices. A telephone call recording device characterized in that telephone calls are stored separately in different files.
