Abstract

PURPOSE:To facilitate the forming of man-machine interface by digitizing a signal of an analog telephone line and converting a signal from a computer into an analog signal to attain the recording/reproduction of the voice of the opposite party and its own device. CONSTITUTION:An analog signal from a telephone line 3 is given from a network control circuit 1 to an A/D converter 3 and its output is fed to a CPU 6 via an interface 5. On the other hand, a digital signal from a CPU 6 is outputted to a telephone line 7 via a D/A conversion circuit 4 and a network control circuit 1. Further, the analog signal is given to a talking circuit 2 in place of the telephone line 7, then the signal from a transmitter of the talking circuit 2 is given to the CPU 6, and the signal from the CPU 6 is outputted to the receiver of the talking circuit 2.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to telephones, and more particularly to multifunctional telephones having signal processing functions.

〔overview〕

The present invention provides a telephone for use with an analog telephone line, which includes means for converting an analog signal from the telephone line into a digital signal and sending it to a data processing device; By being equipped with a means for transmitting to the other party, it is possible to record and play back one's own voice for message and voice recognition of the other party, and for voice response, and to easily form a man-machine interface using this. It is.

[Conventional technology]

Traditionally, telephones have been connected to telephone lines and have been used for voice communication with interlocutors. In recent years, however, it has become possible to perform facsimile communications using acoustic couplers.

[Problem that the invention seeks to solve]

However, in the recent information age, there is a strong demand for telephones to have signal processing functions so that they can be used as man-machine interfaces.

SUMMARY OF THE INVENTION An object of the present invention is to provide a multifunctional telephone that has a signal processing function and can be easily used as a man-machine interface in order to satisfy the above-mentioned needs.

[Means for solving problems]

The present invention provides a telephone set for an analog telephone line, which includes a means for converting an analog signal inputted from the telephone line or a communication circuit of the telephone set into a digital signal and transmitting the digital signal to a connected data processing apparatus; and converting the digital signal into an analog signal and sending it to the telephone line and/or the communication circuit of the telephone.

[For production]

The present invention converts an audio signal input from a telephone line or communication circuit into a digital signal by means of converting and sending an analog signal into a digital signal, and sends the digital signal to a connected data processing device such as a personal computer. . It is thus possible to record messages from the interlocutor or one's own voice responses. Further, the digital data inputted from the data processing device is converted into an analog signal by the means for converting and transmitting the digital signal into an analog signal.
out to telephone lines and/or speech circuits.

Therefore, the more the recorded message from the interlocutor or the user's own voice response can be reproduced, the more arbitrary data can be transmitted.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

The figure is a block diagram showing one embodiment of the present invention. The multifunctional telephone 1o of the present invention includes a network control circuit 1 and a telephone call circuit 2.
The analog-to-digital conversion circuit 3, the digital-to-analog conversion circuit 4, and the telephone line 7 are connected, and the analog-to-digital conversion circuit 3 and the digital-to-analog conversion circuit 4 are connected to each other.
means the computer 6 via the CPU interface 5.
It consists of being connected to.

The feature of the present invention is that, in the figure, an analog-to-digital conversion circuit 3, a digital-to-analog conversion circuit 4, and a CP
This is because the tJ interface 5 is provided.

Next, the operation of this embodiment will be explained. First, when converting an analog signal from the telephone line 7 into a digital signal, the analog signal enters the analog-to-digital conversion circuit 3 through the network control circuit 1, where it is converted into a digital signal.
It is output to the computer 6 via the CPU interface 5. On the other hand, when converting a digital signal from the computer 6 into an analog signal, the digital signal enters the digital-to-analog conversion circuit 4 from the CPU interface 5, where it is converted into an analog signal and sent to the network control circuit 1. It is then output to the telephone line 7. If the analog signal is made to flow to the telephone circuit 2 instead of the telephone line 7, the signal from the telephone transmitter of the telephone circuit 2 will be output to the computer 6, and the signal from the master computer 6 will be output to the telephone receiver of the telephone circuit 2. is also easily possible.

(Effects of the Invention) As explained above, the present invention enables recording of messages from the other party, voice recognition, recording of one's own voice for voice response, etc. by digitizing analog telephone line signals. By converting digital signals from a computer into analog signals, it is possible to respond by voice to the other party, play back recorded messages, etc., and easily create a man-machine interface using answering machines, voice responses, and voice recognition. There is.
