Abstract

PURPOSE:To lessen the capacity of a memory for recording of the voice data, facilitate scanning of the voice data recorded, and make simple documentation of a part which one has missed to listen to. CONSTITUTION:The digital voice data fed from a voice input part 9 is written by a CPU 1 into a sampling buffer 4 endlessly at all times. When a voice take-in order is given from a keybord 5, the CPU 1 accommodates a specified amount of voice data reserved in the buffer 4 in a RAM 3 while the data is related to the document which has been entered in the RAM 3. When a voice reproduce order is given from the keyboard 5, the CPU 1 displays a voice take-in mark in a display device 7, and the voice data corresponding to the voice take-in mark specified by the user who saw it is read out of the RAM 3 and passed to a voice output part 10 so that the voice is reproduced. The user hears this voice and enters the corresponding character string from the keyboard 5, and it is possible to make easy documentation of the part which he has missed to hear.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document preparation apparatus that also uses voice recording, and more particularly to a method for recording and reproducing digitized voice in a memory.

[0002]

2. Description of the Related Art Conventionally, when a minutes or the like of a conference is created using a document creation device such as a word processor, only voice information within a range where a key input catches up is created as a document. Therefore, in order to make a complete recording of the conference, use a tape-type voice recorder together to record all the conversations made at the conference, and then play the tape of the voice recorder. A method has been adopted, in which a voice information portion that cannot be documented due to being overheard is searched for, the voice of this portion is reproduced, and the document is documented by the document creating apparatus to finish the recording of the conference.

However, when such a method is adopted, it is possible to know later which part of the conference the voice was missed. Therefore, the entire conference must be recorded by operating the voice recorder throughout the conference. Nara Katsuta. When an analog tape recorder is used as a voice recorder used for such an application, it is impossible to establish a correspondence relationship between the document input to the document creation device and the voice information recorded in the analog tape recorder. However, there is a drawback that it takes time and effort to find out from the analog tape recorder the audio information portion that could not be documented, and it takes too much time and time to create a complete record of the conference or the like.

Therefore, if the voice of the entire conference is digitized and recorded in the memory, both the document and the voice are digitized. Therefore, the document data input to the document creating apparatus and the voice data recorded in the memory are recorded. It is possible to easily establish the correspondence relation of, and it is also faster to search the voice conversation part that could not be documented later compared to the data formula, so the document recording the conference is completed. However, it has the advantage of saving time and effort. However, the capacity of the memory for recording the audio data of the entire conference becomes enormous, and a digital recorder using such a large capacity memory is usually expensive, and there is a drawback that it is not practical in terms of price. there were.

[0005]

Generally, it is difficult to completely document and record the conference record as described above unless the document preparation device and the voice recorder are used together. Therefore, if an analog tape recorder is used to record the voice information of the entire conference, the above object can be achieved at low cost, but the voice conversation scene recorded in the analog tape recorder and the document input to the document creation device can be recorded. Since it cannot be easily associated with the text, it takes time and time to find and reproduce the conversation part that could not be documented from the analog tape recorder, and in the end, it takes time to completely document the entire conference. There was a drawback that it took too much.

In order to avoid this, if the audio information of the entire conference is digitized and recorded in a memory or the like, the correspondence between the recorded conversation scene and the text of the document input to the document creation device can be easily established. In addition, since it takes no time to search the memory for an undocumented part of the conversation, it is not necessary to fully document the entire conference later. However, the capacity of the memory for recording all the voice information throughout the entire conference becomes enormous, so that the cost of this memory becomes too high, which is not practical in terms of price.

In view of the above, the present invention eliminates the above-mentioned drawbacks, and digitizes the voice information of a part of the conference and records it in a memory having a relatively small capacity. It is an object of the present invention to provide a document creation apparatus that can easily establish a correspondence relationship with each other and document the audio information that is overheard later to complete the entire content of the conference easily and at low cost.

A display device, 8 is a display controller for controlling the display device 7 to display various information, and 9 is composed of a microphone, a voice amplifier, an A / D converter, etc., and converts a voice signal picked up by the microphone into digital voice data. Voice input section,
Reference numeral 10 denotes a D / A converter, an amplifier, a speaker, and the like. A voice output unit that converts digital voice data given from the CPU 1 into an analog voice signal and then outputs the analog voice signal to the outside by a speaker; An external storage device such as a hard disk device for storing data, 12
Is an input / output controller for controlling the input / output of data to / from the external storage device 11, 13 is an address bus, and 14 is a data bus.

Next, the operation of this embodiment will be described. When all the contents spoken in a meeting are documented and recorded using the document creating apparatus shown in FIG. 1, when the user hears the contents of the meeting, the user operates the keyboard 5 to document this.
Since the input / output controller 6 sends the character string input from the keyboard 5 to the CPU 1 via the data bus 14, C
The PU 1 converts it into a sentence by converting it into kana-kanji, stores the obtained sentence in the RAM 3, and displays it on the screen of the display device 7 via the display controller 8. At this time, the voice input unit 9 collects voice information generated in the conference, digitizes it, and passes it to the CPU 1. CPU1
Records the passed digital audio data in the sampling buffer 4. Here, since the capacity of the sampling buffer 4 is only a capacity for recording digital audio data for about 5 minutes, the CPU 1 records the input digital audio data in the sampling buffer 4, but the sampling buffer 4 is full. Then, the input voice data is written from the first address again so that the voice data for about 5 minutes is always stored in the sampling buffer 4.

The user listens to the conversation in the conference and inputs it as a character string from the keyboard 5 into the document creating apparatus. Operate the key. Receiving this, the CPU 1 performs a process of taking the voice data stored in the sampling buffer 4 into the document area in the RAM 3. At this time, if the user could not document a small amount of audio data, the capture key with a small amount of audio data could be captured. If the user could not document a large amount of audio data with a large amount of capture data. push. As a result, when the lesser one of the capture keys is pressed, the CPU 1 retrieves the voice data stored in the sampling buffer 4 from the present for two minutes, stores it in the RAM 3, and then inputs the voice. The voice data input from the unit 9 for about one minute is also stored in the RAM 3 subsequently to the voice data previously stored. CP
When the larger capture key is pressed, U1 reversely retrieves the audio signal stored in the sampling buffer 4 for 5 minutes from the present and stores it in the RAM 3,
After that, the voice data input from the voice input unit 9 for about one minute is also stored in the RAM 3 subsequently to the voice data previously stored. At the same time, the CPU 1 searches the document created in the RAM 3 for a character (corresponding to the last documented character) at a portion interrupted by missing the conversation of the above-mentioned conference, and the attribute area of this character. The address of the transferred voice data is stored in the RAM 3 and a voice capture mark (same as the identification mark) is displayed near the character displayed on the display device 7. Even while performing such processing, the CPU 1 performs processing for constantly writing the audio data input from the audio input unit 9 into the sampling buffer 4.

FIG. 2 is a flow chart showing the above-mentioned processing of the CPU 1 when the user issues a voice information fetching instruction from the keyboard 5. CPU1 is step 201
When it is detected that the capture key has been pressed, the process proceeds to step 202 to transfer the audio data stored in the sampling buffer 4 to the document area in the RAM 3. Next CPU1
Searches for the nearest (last documented) character to the left or above the character input cursor displayed on the display device 7 in step 203, and returns to step 204
The address of the voice data transferred in the RAM 3 is stored in the character attribute area. After that, proceeding to step 205, the CPU 1 displays a voice capture mark near the searched character on the display device 7, and ends the processing. In the above example, the voice capture mark is displayed near the last documented character and the recorded voice data and the character are associated with each other. May be associated with the recorded audio data. In the above example, the recorded voice data is associated with the last documented character, but the voice data may be associated with a character string including this character.

In this way, the user documents the recording of the conference, takes in the audio data of the part which could not be documented, and ends the conference and the recording process of the conference. After that, the voice data stored together with the document in the RAM 3 is reproduced, and the missed part and the like are documented, so that the entire content of the conference is documented and completed. To do this, first issue a command from the keyboard 5 to retrieve the voice data stored in the RAM 3, and then the CPU
1 to perform a search process as shown in FIG. As a result, the CPU 1 checks the attribute information of each character forming the document currently stored in the RAM 3 in step 301, and as a result, whether or not there is a character having a voice data address as its attribute information. To step 3
The determination is made in 02, and if there is not, the process jumps to step 304, and if there is, the process proceeds to step 303. C in step 303
The PU 1 switches the display screen so that a character having a voice data address as its attribute is displayed on the display device 7, and then displays a voice capture mark near the character.
Next, the CPU 1 proceeds to step 304, determines whether or not the above attributes have been checked for all the characters stored in the RAM 3, returns to step 301 if not checked, and ends the processing if checked. To do. The position and number of voice data existing in the document created by such processing are clearly shown to the user.

FIG. 4 is a flowchart showing a process of reproducing voice data designated by the user as voice. The user looks at the voice capture mark displayed together with the created document on the screen of the display device 7 and reproduces the missing voice information in the vicinity where the voice capture mark is displayed to determine whether or not to make a document. After making a decision and designating the voice capture mark to be documented with the cursor on the screen, the voice reproduction key of the keyboard 5 is pressed. In response to such an operation, the CPU 1 reads the position coordinate of the cursor designating the voice capture mark displayed on the display device 7 in step 401, then proceeds to step 402, and an interruption instruction is input from the keyboard 5. It is determined whether or not there is an input, and if it is input, the process is terminated, and if not input, the process proceeds to step 403.

At step 403, the CPU 1 reads the voice data address from the character attribute area near the voice capture mark designated by the cursor, and then at step 404.
Then, the corresponding audio data is read out from the RAM 3 based on the address and is given to the audio output unit 10.
As a result, the audio output unit 10 converts the input audio data into an analog audio signal and outputs it from the built-in speaker. The user listens to the output voice and inputs a character string from the keyboard 5. The CPU 1 documents the characters input from the input / output controller 6 and stores them in the RAM 3
The voice data address is inserted into the continuation of the character having the attribute information and displayed on the display device 7.
When the user misses the sound reproduced from the sound output unit 10 again, the user inputs the repeat key from the keyboard 5. The CPU 1 determines in step 405 whether or not the repeat key has been pressed. If not, the process ends.
If it has been pressed, the process returns to step 402, and the above-described voice reproduction process is repeated. It should be noted that when the user inputs an interruption key from the keyboard 5, the above-mentioned voice reproduction process is interrupted. In the above example, the user presses the repeat key to repeatedly reproduce the recorded audio data, but the recorded data may be repeatedly reproduced a predetermined number of times from the beginning, or it may be repeatedly reproduced. It is normal to do so, and a method may be adopted in which the reproduction is stopped when the user inputs a stop instruction.

In this way, when the entire content of the conference is documented by complementing the portion that could not be documented during the conference, the user deletes the voice data stored in the RAM 3. This includes the display device 7 as in the reproduction process.
This is done by pushing the delete key of the keyboard 5 after moving the cursor to the voice data capture mark displayed on the. That is, when the cursor is positioned at the voice data capture mark and the delete key is pressed from the keyboard 5, the CPU 1 deletes the corresponding voice data from the RAM 3 and also stores the voice data stored in the character attribute area. Related information such as data addresses are also deleted.

Here, when the user edits the document including the voice data as described above, when a character or a character string associated with the recorded voice data is about to be deleted, an alarm sound is given. The generated or warning is displayed on the screen of the display device 7 to inform the user that the character or character string is associated with the recorded voice data. If the user deletes the character or character string associated with the recorded voice data despite the warning, the character or character string remaining in the vicinity of the associated character or character string or The voice data may be newly associated with the character string.

According to the present embodiment, the digitized voice data is always held in the sampling buffer 4 by a predetermined amount, and is stored in the sampling buffer 4 only when the voice capturing instruction is given by the user. The voice data stored in the RAM 3 is stored in association with the document data already input, and then the voice data stored in the RAM 3 is reproduced by the voice output unit 10 to complement the portion that could not be documented. It is possible to reduce the capacity of the sampling buffer 4 that stores the audio signal, and prevent the device from becoming expensive. Moreover, since the missed-out voice data is stored in the RAM 3 in association with the already-input document, it is very easy to search for the missed part, and the document can be complemented easily and in a short time. it can. In the above embodiment,
Although the user manually selects the voice data to be reproduced, this is automatically associated with the recorded voice data, that is, the CPU 1 is associated with the recorded voice data in the characters of the document data stored in the RAM 3. When the characters are searched out in order from the top, it is possible to display the display device 7 as to whether or not to reproduce the audio data corresponding to the character so that the audio data to be reproduced is automatically selected. .

[0020]

As described above, according to the document creating apparatus and the voice data recording / reproducing method of the present invention, the voice information of a part of the conference can be digitized and recorded in a memory having a relatively small capacity. The correspondence between the text and the voice information part that could not be documented can be easily established, and the voice information that has been missed can be documented later to completely and easily document the entire contents of the conference.
