The device for this purpose is a voice message writing device.

This type of voice message writing device has an internal memory for temporarily recording a voice message, and writes the voice message recorded in this internal memory to the internal memory of a voice synthesis card. Some voice message writing devices are also known to be equipped with a cassette tape deck for recording voice messages previously recorded on a cassette tape into its internal memory.

Conventionally, in order to record a voice message input from a microphone into the internal memory of a voice message writing device, it was necessary to press a recording button provided on the front panel of the voice message writing device, or to record a voice message input from a microphone into the internal memory of a voice message writing device. To record the voice message pre-recorded in 1 to the internal memory of the voice message writing device, press the above record button and the play button of cassette 1 deck. Once recorded in the internal memory of the device, the voice message writing device enters a standby state in which the voice message recorded in the internal memory can be written to the internal memory of the speech synthesis card. In this standby state, by setting the voice synthesis card in a predetermined position and pressing the write button provided on the front panel,
The voice message recorded in the internal memory of the voice message writing device is written to the internal memory of the voice synthesis card.

[Problems to be Solved by the Invention] However, if the record button is pressed by mistake during the above-mentioned standby state, the voice message that has already been recorded in the internal memory of the voice message writing device is erased, and the microphone This may result in undesired background noise such as voices being recorded in the internal memory of the voice message writing device.Also, in the above-mentioned standby state, pressing the play button on the cassette tape deck may cause undesired background noise to be recorded on the cassette tape. If you accidentally press the record button while playing a voice message, the voice message that was already recorded in the internal memory of the voice message writing device will be erased and the voice message that was previously recorded on the cassette tape will be erased. However, there is a drawback in that the next voice message sent is recorded in the internal memory of the voice message writing device.

When it is detected that the recording button 191 has been pressed again (YES in step 102), the recording process is started for the first time (step 103).

Conventionally, when the recording button 191 was pressed, recording processing was started immediately. Therefore, as described above, there is a risk that an unnecessary voice message may be recorded by mistake. In contrast, in the present invention, as described above, the recording process starts only when the reset button 194 is pressed, the record button 191 is pressed, and the record i 191 is pressed again. You can prevent it from being recorded.

After such a recording operation, the CPU 30 performs recording processing to the SRAM 48, 49 as described below.

When recording a voice message input from the microphone 11, the input voice message is input to the voice message writing device 10 from the insertion port 12, and is sent to the AGC circuit 43 via the amplifier 45 and switch 5141.
Enter.

On the other hand, when recording/sounding a voice message pre-recorded on the cassette player 1, the CPU 3G detects that the playback button 161 of the operation buttons 16 is pressed and presses the switch 5141.
and 812 is inverted, that is, switched to the normally open contact side, and the driver circuit 4 is connected via the I10 interface 33.

As a result, the cassette tape deck 13 is driven for reproduction by the driver circuit 41, and the voice message recorded on the cassette tape set in the cassette tape deck 13 is reproduced. This reproduced reproduction signal is transmitted to the amplifier 42
After being amplified, the signal is input to the AGC circuit 43 via a switch 5141.

In this way, the audio signal input to the AGC circuit 43 undergoes automatic volume adjustment here, and then its sound pressure level is detected by the level detector 46, and the level detector 46 sends the level detection signal via the I10 interface 33. and sends it to the CPU 30. In response to this level detection signal, the CPU 3G sends a display signal H3 indicating the sound pressure level to the second bar graph 212 via the I10 interface 33. As a result, the sound pressure level is displayed on the second bar graph 212.

Note that when recording a voice message prerecorded on a cassette tape, the switch 3141 is inverted, so the output signal of the AGC circuit 43 is output from the switch SW2,
Through the volume 23 and amplifier 44, the speaker?
2 is uttered as voice.

Further, the CPU 30 determines whether the sound pressure level is equal to or higher than a predetermined level based on this level detection signal, and if the sound pressure level is equal to or higher than the predetermined level, the CPU 30 transmits the signal to the speech synthesis analysis circuit 47. Voice analysis commands are sent via the I10 interface 33 and data bus. As a result, registration of the voice message to the SRAM 48, 49 is started. - That is, in response to this voice analysis command, the voice synthesis and analysis circuit 47 conducts a voice analysis on the output signal of the AGC circuit 43, and sends the analysis result as voice analysis data to S.
Record to RAM48.49.

At the same time, the CPU 3G monitors the elapsed recording time, sends a signal H3 indicating the elapsed recording time to the first bar graph 211 via the I10 interface 33, and causes the first bar graph 211 to display the elapsed recording time. .

Here, when 8 seconds is selected as the recording time with the first recording time selection button 201, the voice analysis data is recorded only in the SRAM 48, but when the recording time is selected with the second recording time selection button 202, the voice analysis data is recorded only in the SRAM 48. When 16 seconds is selected, voice analysis data is recorded in both SRAMs 48 and 49.

If you want to include BGM at this recording stage, please select BG.
It is also possible to select a song by pressing the M button 195 and pressing any one of the numeric keys 28.

When the recording time selected by the first recording time selection button 201 or the second recording time selection button 202 has elapsed, the CPU 3G sends a termination command to the speech synthesis analysis circuit 47, and the recording to the SRAM 48.49 is performed. complete.

After this recording is completed, the operator presses the playback button 192 of the message button 19 to check whether the voice analysis data recorded in the SRAM 48, 49 has been recorded properly. CP that detected that
U3G sends a speech synthesis command to speech synthesis analysis circuit 47. In response to this speech synthesis command, the speech synthesis analysis circuit 47 reads out the speech analysis data recorded in the SRAM 48, 49, performs speech synthesis, and sends the synthesis result to the LPF 50 as a speech synthesis signal. The LPF 50 blocks high frequency components of this voice synthesis signal. The output signal of the LPF 50 is sent to the switch needle 2, the volume 23, and the amplifier 4.
4, the voice is output from the speaker 22.

If it is determined to be good after this check, the SRAM48.49
In order to write the recorded voice analysis data into the internal memory of the voice synthesis card, the operator first sets the voice synthesis card in the card attachment 17.Next, the operator presses the write button of the message button 19. When the CPU 30 detects that the write button 193 has been pressed, it sends a write command to the SRAM 48, 49 and sets the input/output control circuit 52 to output mode. As a result, S
The voice analysis data recorded in the RAM 48, 49 is sent to the input/output terminal 17a of the card attachment 17 via the input/output control circuit 52, and written to the internal memory of the voice synthesis card. The internal memory of this speech synthesis card is
For example, an EPROM typically takes about 4 minutes to write.

If it is determined that the above check is defective, the operator presses the reset button 194 of the message button 19. When the CPU 30 detects that the reset button 194 has been pressed, the CPU 30 outputs the voice recorded in the SRAM 48.49. After the voice analysis data recorded in the SRAM 48.49 is erased, the operator performs the process of erasing the analysis data.
By performing the above operation again, the SRAM48
．． 49, voice analysis data is recorded.

When the above writing is completed, take out the voice synthesis card from the card attachment 17.The voice synthesis card has an optical switch and a speaker, and after covering the optical switch with your hand for a predetermined period of time (for example, 3 to 5 seconds), remove the voice synthesis card from the card attachment 17. When you release your hand, the voice message written in the internal memory of the voice synthesis card is uttered as voice from the speaker. If the uttered voice is good, the voice synthesis card is stored in an outer case suitable for the purpose. The outer case containing the voice synthesis card is handed over to a desired recipient by mail or the like.

By installing a telephone line unit in this voice message writing device, it is also possible to record voice messages via the telephone line in the voice message writing device.
