Abstract

PURPOSE:To obtain an efficient recording state by stopping tentatively the recording when a message is intermitted during the recording of the message to record the message while its silence part is squeezed and stopping the reproduction at the silence part squeezed at the recording tentatively in reproduction. CONSTITUTION:After the transmission of a reply message, a message from an opposite party is to be recorded, but the recording is not immediately entered, after an allowable time is set when the silence part continues and a signal level is monitored by a level detection circuit 10 and when a signal of a prescribed level or over comes, it is discriminated that the message is in existence and it is recorded. That is, the message is converted into a digital data by an A/D converter 11 and stored in a message area of a RAM 3. Moreover, the signal level is always monitored by the level detection circuit 10 during the recording of the message and when the level is a prescribed level or below, the output of the A/D converter 11 is not used and the write of the voice data is stopped till the voice level exceeds the prescribed level.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an answering machine.

[Prior Art] When a conventional answering machine receives a call while the answering machine is set to answering mode, it automatically receives the call, sends a pre-prepared response message to the other party, and then magnetically transfers the other party's message. Record on tape or audio ice. This recorded message can then be played back later so that the user can listen to the message on the phone.

[Problems to be Solved by the Invention] However, in the above conventional example, since the recording operation is performed even when the business message is interrupted, silent recording portions occur in the limited area of the recording device. So, record 1 of effective messages? I ended up reducing the makima, and as a result, the record i'? The drawback was that it reduced the number of cases.

An eleventh object of the present invention is to provide an answering machine that can record only valid business messages, allow the recording device to function efficiently, and provide good playback conditions.

[Means for Solving the Problems] The present invention provides an answering machine that records a message from the other party after returning a message in response to an RI call in the answering mode, when the message is recorded while the voice message is being recorded. Stop recording when the message is interrupted 1-
The feature is that during playback, that part is temporarily stopped.

[Function] According to the present invention, if the message is interrupted during recording of the business message, the recording is stopped. Therefore, if the voice from the other party is intermittent, the silent part can be closed and recorded efficiently. can do.

In addition, during playback, since the blank 1" f part that was closed at 1 o'clock in the recording is stopped 1-, x, !, joint parts, etc. are faithfully i
FT reproduction, and a good reproduction condition that is easy to hear can be obtained.

[Embodiment] FIG. 1 is a block diagram showing an answering machine according to an embodiment of the present invention.

The control section J has a function as a main control section of the answering machine, and is composed of a microprocessor and the like.

ROM2 is a memory that stores a control program for the control unit 1, and RAM3 is a memory used for a work area of the control unit 1, a calling telephone number buffer, a response message area, a reception (fl) message area, etc. It is.

Further, the operation section 4 is used to perform various operations on the answering machine, and the display section 5 is used to display operation guidance and the status of the telephone.

Furthermore, this '11i handset has a response message record i'.
Micro for 1, closing the telephone line and 2 wire 4! Ia
A speech network 7 that performs conversion, a dialer 8 that sends a dial signal when waiting for a call, a handset 9 for sending and receiving calls, a level detection circuit 10 that detects a constant 1/bell signal, and a digital voice signal converter. Convert to data A
A /D converter 11, a D/A converter 12 for converting audio signals into digital data, and the like are provided. Further, a plurality of telephone lines 13 are connected to the speech network 7.

In this embodiment, the A/D converter 11 converts the voice of the same line 13 into digital data and stores it in the RAM 3, thereby recording the 11 message when the user is away.

In addition, the bold line among the lines 1;- in the figure is the sound j! '4! The diagonal line indicates the signal line of the A/D converted digital data.

FIG. 2 is a flowchart 1 for explaining the operation of such a telephone in the absence mode.

11. It is assumed that the response message has already been recorded i'1 and the telephone set is set to the answering mode.

First, when a call comes in (31), it is automatically received through the speech network 7 (S2), and
3, the response message stored as digital data is sent out through the D/A converter 12 (S3).

After sending the response message, the message from the other party will be recorded, but the recording operation will not be performed immediately, but after setting the allowable waiting time in case there is continued silence (
S4), the signal level is monitored through the level detection circuit 10, and when a signal of - above a certain level comes, (S4)
5) Determine that the message is correct and record it (S6)
. That is, the message is converted into digital data by the A/D converter 11 and stored in the message area of the RAM 3. In this embodiment, it is assumed that the digital output of A/D conversion has a width of 6 bits, and the data exchange between the CPU 1 and the RAM 3 has a width of 8 bits. Therefore, do? Voice digital data is hexadecimal OO]1~
It can take a value of 3Fu.

Also, for! 1- While recording a message, the signal level is constantly monitored through the level detection circuit 10, and if it falls below a certain level (S7), FFH is stored in the RAM 3 as a pause code instead of the output value of the A/D converter 11. (S9.510), and the writing of audio data is stopped until the audio level exceeds a certain value (S8).

After that, repeat this operation, and when the silence continues for a certain period of time (S11), release the line (Sl, 2).
, return to standby state.

FIG. 3 is a flowchart 1 showing the operation when reproducing a business message.

During this playback, the audio digital data stored in the business message area of RAM 3 is converted into an analog signal through the D/A converter 12 and output (S33), but the audio digital data is FFII (pause code). (S31), the output is stopped for a certain period of time (S32).
).

In addition, in the explanation below, if the message is
When the sound level drops below a certain level, a pause code is written uniformly, and during playback, playback is stopped for a uniform period of time based on the detection of the pause code.However, when recording, for example, every 3 seconds of silence, a pause code is written. The code may be written, and during playback, the playback may be stopped for 3 seconds every time a pause code is detected, thereby obtaining a playback stop time corresponding to the silent time.

[Effects of the Invention] As explained above, according to the present invention, when a business message is being recorded and the message is interrupted, the recording operation is temporarily stopped, and the silent part is closed and recorded. At the same time, during playback, the silent parts that were recorded during recording are paused, making it possible to obtain an efficient recording state while maintaining an easy-to-hear playback state that faithfully reproduces breathing parts, etc. This has the effect of increasing the number of recordings.
