Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a voice message device with a semiconductor type recording/playback function that applies voice analysis and synthesis technology to the recording and playback of voices.

<Prior Art> Conventional voice message devices have been proposed, including mechanical ones that use recording tape and semiconductor-type voice message devices that apply semiconductor-based voice analysis and synthesis technology. Because of this, it was difficult for the person trying to record to understand when the recording time ended from the start of recording. Even if a message ends early, recording continues until the capacity of the recording tape or semiconductor memory runs out, and if the message is long, the recording tape runs out or the capacity of the semiconductor memory exceeds the capacity of the semiconductor memory, causing the end of the message to be It was ranked second in that it was often not recorded.

In addition, in the semiconductor type, if you change the sampling time for analyzing the audio signal of the audio analysis and synthesis LSI, the recording time will change by changing the sampling time, but since there is no display of the recording time, the recording time will not be recorded. Problems such as difficulty in understanding the length and shortness of time and the inability to utilize semiconductor memory effectively have arisen.

In a mechanical device using a recording tape, it is difficult to synchronize the running of the recording tape and the recording time, making it difficult and complicated to display the recording time, and moreover, it is expensive.

Since recording tape is used, there are problems due to tape wear and the complexity of the mechanical parts, and maintenance such as tape replacement is also required. Furthermore, after the recording is finished, a mechanism for rewinding or cueing to the point at which the recording started is required, resulting in a number of operations.

Purpose of the present invention In view of the above points, an object of the present invention is to provide a display section that can be easily understood by a person who intends to record the recordable time or elapsed time during recording, and to sequentially light or blink the lamps forming the display section. The main purpose is to display the decrease in recording time depending on the situation, so that you can easily understand the remaining time.Furthermore, when the set remaining time is reached, the color tone of the display changes and the flashing speed changes to show the remaining time. By this, the person trying to record a message, etc. knows the recording time and the remaining time, and can summarize the message content in a concise manner, eliminating inconveniences such as missing the ending of the message, and improving operation. To provide a voice message device that is easy to use, and to provide a convenient voice message device in which the recorded time is displayed as the playback time when the message is played back so that the time of the message can be easily understood.

<Embodiment> An embodiment of the voice message device of the present invention will be described below with reference to the drawings.

In FIG. 3 is a microphone for inputting a message, and 4 is a recording button to be operated when attempting to record the contents of the message. 5 is an erase button for erasing recorded content.

6 is a change-over switch for setting the sampling time for analyzing the audio signal of the audio analysis and synthesis LSI (described later).When inputted alternately, the 0 display lamps 7 and 8 change the sampling time alternately from long to short to long to long. It blinks according to each sampling time and indicates the sampling time, 0, that is, the recordable time.In general, the practical recording time for a voice message device is about 8 to 40 seconds. The recording time in the invention is switched in two stages: 16 seconds and 32 seconds. It goes without saying that the recording time can be extended by increasing the capacity of the semiconductor memory, and 09 is a recording indicator lamp that displays the recording time, and in the present invention, it is linearly displayed as 91, 92, 93, etc. 96/97/98
Eight lamps are lined up, and each lamp corresponds to one recording or playback time.

That is, when the changeover switch 6 is pressed to turn on the display lamp 8, if the recording time is 16 seconds, the time per recording indication lamp 9 will be 2 seconds, and then when the changeover switch 6 is pressed, Indicator lamp 7 should light up Indicator lamp 8

It lights up as 92, 93, 94, 95.

Also, if the recording time is reduced (in the present invention, the recording time is 1
(When set to 6 seconds, it is set to 6 seconds, and when set to 32 seconds, it is set to 12 seconds, but there is no need to stick to this and you can set it as appropriate.) Change the color tone of the lamp lighting.

For example, if the numbers 91 to 95 are displayed in green and the numbers 96 to 98 are displayed in red, the person recording can easily see that there is little recording time left, which is very convenient for handling. As another example, 96 to 98 may be blinked at a certain period without changing the color tone.

Next, the circuit configuration of one embodiment of the voice message device of the present invention will be explained in a second embodiment.
This will be explained with reference to the block diagram in the figure.

All you need to know is that the display is different from 1 to 95.O 12 is a speaker for audio output. This corresponds to each of the figures in Fig. 1. Reference numeral 13 denotes an audio output unit that amplifies the recorded content as an audio signal outputted from the audio analysis stand ffLsI+4 and drives the speaker 12. 15 is a microcomputer (hereinafter referred to as CPU) that controls the system (device) of the present invention. ■6 is speech analysis synthesis LS11
This is a semiconductor memory for storing the data analyzed in step 4. In the example of the present invention, the pit rate of the sampling time is set to 16 kilopits/second, which is the core of the present invention. (16kb it/s) and 3
Two types of speed can be selected: 2 kilobits/second (32kbit/s). That is, the CPU1 is set by the changeover switch 6.

Hereinafter, an example of the operation of the voice message device of the present invention will be explained with reference to the flowcharts of FIGS. 3 and 4.

First, the case where a memo is recorded as voice on the voice message device will be explained with reference to the flowchart of FIG.

When the recording button 4 is input, the CPU 15 receives this input and first sets the voice analysis and synthesis LS 114 to the recording mode. Next, the bit rate of the sampling time using the changeover switch 6 is instructed to the audio analysis and synthesis LS 114. For example, if it is set to 16 kbit/s, this bit rate is instructed to the speech analysis and synthesis LS 114. Voice analysis stand #: LS114 receives this from CPU15, analyzes and converts the message as a voice memo input from microphone 3 into voice data, and stores it in semiconductor memory 16. Further, the CPU 15 sequentially displays the recording time display lamp 9 as the recording time elapses at the same time as the recording button is pressed. That is, in the case of 91, 92, 93, . . . 95 in the above example, the pit tray is displayed in units of 2 seconds in the case of 16 kbit/s, and in units of 1 second in the case of 32 kbit/s. When the remaining time decreases, 96 to 98 change the color tone (in the description of the present invention, the color tone is changed from green to red or 96 to 98 are blinking in the same color) or may be blinking. When the recording time has elapsed, all the recording time display lamps 9 are turned on, and after the set time elapses (pu+5, the recording display lamp 9 is turned off. When the recording display lamp 9 is turned off, the recording of the message ends, and the CPU 15 The voice analysis and synthesis LS114 is returned to standby mode, voice analysis is stopped, and storage in the semiconductor memory is also stopped.Then, the message lamp 2 is turned on to indicate that a message is being recorded.In case of recording mode or standby mode. In this case, the CPU 15 outputs a signal to cut off the switching transistor 18 in order to stop the operation of the audio output section 13.No audio is output from the speaker 12.

Next, the case of reproducing message contents will be explained with reference to the flowchart of FIG. 4.

Message lamp 2 lights up to confirm that the message is being recorded, and then presses the playback button □ In response to this, cputs sends a 0-bit rate instruction to put speech analysis and synthesis LS114 into playback mode.
instruct. The cputs outputs a signal that turns on the switching transistor 18, operates the audio output section, and the speaker 12 becomes able to output audio. Next, the recording time display lamp 9 is turned on to display the playback time. As the playback time elapses, the recording time display lamp 9 is turned on 91
92...95 and changed the color tone (blinking is good power →
96, 97, and 98 are lit to display the playback time.

The bit rate per indicator lamp is 16, which is the same as the recording time.
4 seconds for kbit/s, 2 seconds for 32 kbit/s 0 Speech analysis stand @: When the LS114 is set to playback mode by the instruction of cputs, the speech analysis and synthesis LS
114 sequentially reads the audio data stored in the semiconductor memo IJ-16, synthesizes the audio data, and outputs the synthesized audio data to the audio output section 13 as an audio signal.

The audio output unit 13 amplifies this audio data and outputs it to the speaker 1.
2, the contents of the message are output as audio.

As the playback time elapses, cputs turns off the recording time display lamp 9 and puts the speech analysis and synthesis LSI 4 into standby mode. When the standby mode is entered, reading from the semiconductor memory 16 is stopped and cputs is switched to the switching transistor 18.
is turned off to stop the operation of the audio output section 13.

It is also possible to display the recorded time of the message on the recording time display lamp 9 for a set time by controlling the CPU 5, and by displaying this, it is easy to know the time of the message to be played back. . That is, the recording time display lamp 9 is lit up in accordance with the message time stored in the semiconductor memory 16. For example, if 91, 92, 93, and 94 of the recording time display lamp 9 are lit, it means that the message time is 16 seconds when the bit rate is 16 kbit/s, and 8 seconds when the bit rate is 32 kbit/s. It's easy to understand.

If the contents of the message are to be deleted, by inputting the delete button 5, cputs deletes the contents of the semiconductor memo 17-16 via the voice analysis/synthesis LSII 4.

Furthermore, if message rung 2 is lit (message present), it is turned off. Furthermore, if it is desired to record a message for a longer time, the bit rate can be changed using the changeover switch 6 to increase the length of the message. In the present invention, an example in which recording times of 16 seconds and 32 seconds can be selected is explained, but there is no need to be limited to this, and it is also possible to make various selections, and the recording time can be easily determined by the display lamp.

Effect> Since the voice message device of the present invention has the above configuration,
When trying to send a message, the person trying to record can see the elapsed recording time in advance, the person trying to record can examine the contents of the message, and the end of the message will not be missing, and even if it is missing, it can be easily done. It is very convenient to be able to re-record the message, and when it is played back, the elapsed playback time can be seen, allowing the person listening to the message to predict the end of the message or know in advance the time of the message, which is very convenient.

Furthermore, the recording time can be selected to be long or short as necessary, and the display can be easily confirmed, making it extremely easy to operate and handle.
