Abstract

PURPOSE:To provide the titled automatic answering telephone set with a ordinary automatic answering telephone function and a remote operation reproducing function and to omit carrying of an outgoing trunk equipment by using a secret voice fixed by the subscriber himself as a control word and providing the telephone set with a voice recognizing circuit controlling switching to recording or reproducing of the automatic answering telephone set by the control word. CONSTITUTION:The automatic answering telephone set is provided with a microprocessor 8 controlling the whole system, and when the telephone set 4 is accessed by dialing, the processor 8 actuates a voice response message reproducing tape recorder 1 or an automatic answering telephone set recording/reproducing tape recorder 5. The voice recognizing circuit 7 is connected to the telephone set 4 in the automatic answering telephone set through a BPF 6 and the output of the circuit 7 is applied to the processor 8. A secret voice fixed by the telephone subscriber himself is used as a control word and the control word is supplied to the circuit 7, which confirms whether the control word indicates recording or reproducing of the automatic answering telephone set and applies its output to the processor 8. Thus the automatic answering telephone set is provided with the ordinary automatic answering telephone function and the remote operation reproducing function.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a remote control type answering machine having an automatic answer recording function.

Conventional configuration and its problems In general, remote controllers with automatic response recording function) o-
A telephone answering machine has the normal answering machine function of recording the contents of the caller's message, and the function of controlling the answering machine using the telephone line to play back and listen to the contents of the answering machine in a remote location. It has the ability to The switching of the above functions in this answering machine is achieved by transmitting a coded signal from a small transmitter carried by the telephone subscriber personally when playing a response message from the answering machine, and processing the entire signal. Switch the answering machine to playback mode.

If the output signal from the transmitter is not input from the telephone, it operates as a recording function of a normal answering machine. However, although the above-mentioned answering machine can open the contents of the recorded tape on the answering machine at a remote location, it is not only very cumbersome because the transmitter must be carried at all times. There was a problem in that there was a risk that the device could be used for eavesdropping if the device was lost.

OBJECT OF THE INVENTION The object of the present invention is to provide a normal answering machine function that records the contents of a caller's message under the control of voice signals, and a function of reproducing and listening to the contents of the answering machine at a remote location. Our goal is to provide an answering machine that can do the job.

Structure of the Invention The answering machine of the present invention uses a secret word determined by an individual telephone subscriber as a control word, and is equipped with a voice recognition circuit that uses this control word to control switching between answering machine recording and playback of recorded content. It is something. As a result, a secret word determined by each telephone subscriber is used as a control word, and this control word is used in place of the coded signal of a portable transmitter, eliminating the hassle of carrying a transmitter. This has the advantage of eliminating the risk of eavesdropping when the transmitter is lost.

DESCRIPTION OF EMBODIMENTS The present invention will be described below with reference to drawings of embodiments. The figure shows one embodiment of the present invention, and in the figure, 1 is a tape recorder for playing back voice response messages, and 2 is an adder for the reproduced sounds of the tape recorder 1 for playing back voice response messages and the tape recorder 5 for recording answering machines. , 3 is a band elimination filter that eliminates a plurality of specific bands, 4 is a telephone, 5 is a tape recorder for recording an answering machine that records the contents of a caller's message when the call is answered while the phone is away, and 6 is a band A band pass filter having the same center frequency as the removal filter 3, 7 a speech recognition circuit which receives the output of the band pass filter 6 as an input signal, and 8 a microprocessor that controls the entire system.

In the above configuration, when the caller dials in to the telephone 4 using an external telephone, the handset 4' of the telephone remains set in the telephone, so the control basis of the microprocessor 8 of the answering machine main unit is not activated. A voice response message is outputted from a voice response message reproducing tape recorder 1, passes through a telephone set 4 after a specific frequency is removed by a band elimination filter 3, and conveys the voice response message to the caller. If the caller is not the owner of the answering machine, the microprocessor 8 stops the voice response message playback tape recorder 1 and activates the answering machine recording and playback tape recorder 5 after the voice response message is finished, and the caller's Record a message. on the other hand,
When the caller is the owner of an answering machine and wants to listen to the recorded contents of the answering machine's recording/playback tape recorder 5, the conventional method connects the telephone line and activates the transmitter carried while the answering message is being played back. Then, the answering machine recording and reproducing tape recorder 5 is put into recording mode. This embodiment makes it possible to operate the device using words (control words) determined by the owner without using a transmitter. The problem with controlling the answering machine by voice is that even if a control voice is input during playback of the voice response message tape recorder 1, the voices are superimposed and it is impossible to separate the voices. It is. If there is no telephone line attenuation,
If a voice response message cancellation circuit is added to the input section of the voice recognition circuit, it can be separated from the control word, but if the attenuation level of the line exceeds 20 dB, the control word will be canceled due to leakage of the response message through the line. cannot be separated. Therefore, in this example, even when a voice response message is reproduced, the telephone answering machine can be controlled by voice even when the voice level of the line is attenuated. First, since the sound played by the voice response message playback tape recorder passes through the band elimination filter 3 and is sent to the telephone line after removing a specific frequency band, the sound quality of the sound is slightly degraded. The control word for speech recognition is passed through a 4if pass filter whose center frequency content is -,
By using the output as an input to the voice recognition circuit 7, the output of the band pass filter 6 becomes only the voice of the caller. Thereby, even when a voice response message is played back, it can be separated from the control word, voice recognition is possible, and the answering machine recording/playback tape recorder 5 can be switched from the recording mode to the playback mode. Also, when listening to the contents of the answering machine recording and reproducing tape recorder 5 in the playback mode, by passing the recorded contents with normal frequency characteristics through the band elimination filter 3 and playing back, there are two It is possible to recognize voices and control playback, fast-forwarding, etc.

Effects of the Invention As detailed above, according to the present invention, a secret word determined by an individual telephone subscriber is used as a control word, and this control word can be used to control all switching between answering recording and playback of recorded contents by voice response. The structure allows voice recognition to be performed even when playing messages, etc., so individual answering machine subscribers are freed from the hassle of having to carry a transmitter with them at all times, and it also prevents eavesdropping when the transmitter is lost. It has the advantage of being free from danger.
