Abstract

(57) [Summary] This bulletin contains application data before electronic filing, so abstract data is not recorded.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a data filing method, and in particular, to a data filing method that allows a quick search for desired data from a plurality of digital data or audio data. Regarding the method.

[Conventional technology]

Generally, data files for computers etc. are created by giving the data a file name and storing it on a recording medium such as a disk. , only the file names are read out and a list of them is displayed on a display or the like. In addition, in voice memo devices that convert the user's voice into digital audio data, store it on a recording medium such as a disk, and read it out and reproduce it as audio when necessary, when writing the audio data to the disk, etc. Use an input device with a display and a keyboard to assign a file name and write it in the same way as for normal data, display this file name visually, and write the file name of the audio data on the disc. It was something to investigate.

However, when storing digital data or audio data in a device that does not have a keyboard or display, such as a tape recorder, there is no prior art that allows this data to be used by giving it a file name. The only known conventional technique is to store digital data and audio signals as a pair for each unit of data in a card-shaped recording medium, as described in, for example, Japanese Patent Application Laid-Open No. 60-84572.

[Problem that the invention seeks to solve]

The conventional technology described above is a device that does not have a keyboard or display, and is capable of recording digital data or audio data, assigning file names to this data, or searching for necessary data based on the file name. However, there was a problem in that the content could not be confirmed unless the digital data was sequentially used or the audio data was played back sequentially.

SUMMARY OF THE INVENTION An object of the present invention is to provide a data filing method that makes it possible to quickly and continuously search for target data from a plurality of digital data, q audio data, etc.

[Means for solving problems]

According to the present invention, the purpose is to store data such as digital data, audio data, etc. in a data file.
A voice index section corresponding to one-to-one correspondence is provided, and when data is stored, the voice data serving as an index is stored in the index section.When searching, only the voice index section is played back, and the reproduced index is converted into voice. This is achieved by listening carefully.

[Effect]

When creating a data file, after finishing recording a predetermined voice memo or inputting predetermined digital data, the operator records a voice that becomes an index that matches the content of the data as a voice index. This audio index and data as a file are stored in a file in a one-to-l correspondence.

When it is desired to search for desired data from among the created data files, only the audio index section is sequentially reproduced, and only the index is sequentially displayed as audio. By listening to this audio index, the operator can search for the desired digital data or audio data such as a voice memo, or after listening to the index corresponding to the desired data pressure, start the data playback By performing the necessary operations, you can output the desired data from the data file.

〔Example〕

Hereinafter, one embodiment of the data file system according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a voice memo device to which the present invention is applied, FIG. 2 is a diagram showing an example of the configuration of a data file, and FIG. 3 is a control unit explaining the operation of the device shown in FIG. 1. It is a processing flowchart.

In FIG. 1, l is a data file, 2 is a control unit, and 3 is a data file.
4 is an input interface section, 4 is a voice analysis section, 5 is a voice input section, 6 is a voice synthesis section, 7 is a loudspeaker, 8 is a voice recording switch, 9 is a voice playback switch, and 10 is a voice index switch.

As shown in FIG. 1, a voice memo device which is an embodiment of the present invention has a data file 1 that stores digitized voice data of a voice memo to be recorded and a file name corresponding to this voice data. , a voice analysis unit 4 that converts voice signals from a voice input unit 5 such as a microphone into digitized voice data, and an input that provides operation signals from a recording switch 8, a playback switch 9, and a voice index switch IO to the control unit 2. an interface section 3; a speech synthesis section 6 that converts the audio data provided from the control section 2 into an analog signal and outputs it to the loudspeaker 7; Store data in data file l and read from data file 1. f, and a control section 2 that controls the overall operation of the voice memo device, such as supplying data to the voice synthesis section 6.

The data file 1 may be an IC memory card, a magnetic disk device, etc., and is composed of a file section 21 and a directory section 22. The file section 21 is composed of an audio data section that stores audio data obtained by digitizing a voice memo to be recorded, and an index section that stores audio data of the file name of the data. The audio data section includes a plurality of sets of data each including the start address and end address of each audio data of the audio data section stored in the audio data section 21 and the start address of the index corresponding to the audio data. The length of the audio data recorded in the file 1 may be arbitrary depending on the length of the audio memo, and the audio data is sequentially stored in the data file 1 according to the length.

Next, the operation of the voice memo device shown in FIG. 1 will be explained according to the processing flow of the control section 2 shown in FIG. 3.

(1) When recording a voice memo on the voice memo device, the operator inputs voice from the voice input unit 5 while pressing the voice recording switch 8. The input interface unit 3 notifies the control unit 2 that the audio recording switch 8 is pressed. After confirming that the voice recording switch 8 is pressed and that the voice index switch 10 is not pressed at the same time, the control section 2 outputs a voice analysis command to the voice analysis section 4 (Flows 31 and 32).

(2) The voice analysis unit 4 starts analyzing voice according to the voice analysis command from the control unit 2. The voice input from the voice input section 5 is analyzed in real time by the voice analysis section 4,
It is passed to the control unit 2. The control unit 2 sequentially stores the analyzed and digitized audio data in the empty area of the audio data section in the audio file l. When the operator finishes recording, he stops pressing the audio recording switch 8, so the input interface section 3 notifies the control section 2 of this. The control section 2 issues a command to the speech analysis section 4 to stop the analysis, thereby causing the speech analysis section 4 to stop the analysis. After recording this audio data,
The control unit 2 copies audio data for a certain period of time, for example, 2 seconds, at the beginning of the audio data portion in the data file 1 for which recording has just been completed, to the index portion as an index of this audio data (Flow 33).

By the above-described operation, the voice memo is recorded in the data file 1 as a digitized voice data, and at the same time, its index is recorded as voice data.

(3) If the operator determines that the index recorded above is inappropriate as an index for the recorded audio data, immediately after the end of the recording, the operator presses the audio index switch 1o and By pressing the sound switch 8, an appropriate index can be recorded in the index section of the corresponding audio data. That is, after confirming that the voice recording switch 8 and the voice index switch 1o are pressed, the control unit 2 instructs the voice analysis unit 4 to start analysis, and saves the newly input voice index to the data file 1. Store it in the index section of The recording process in this case ends in 2 seconds, which is the fixed time described above (Flows 31 and 3).
2.34).

When the control unit 2 finishes the above-mentioned recording operation, it writes the start address of the index of the audio data just recorded, and the start and end addresses of the audio data to a predetermined position in the directory unit 220 in the data file, and starts a series of recordings. Finish the process.

(4) When playing back audio data that has already been recorded,
The operator presses the audio reproduction switch 9 while pressing the audio index switch 10. The input interface unit 3 notifies the control unit 2 that the audio index switch 10 is pressed simultaneously with the audio playback switch 9.

The control unit 2 confirms that these switches 9 and 10 are pressed, completes the process of reading out the audio indexes in the data file 1, and sequentially sends the read indexes to the audio playback unit 6. The audio reproduction unit 6 converts the index audio data from the control unit 2 into an analog signal and outputs it as an audio display from the loudspeaker 7 (Flows 31 and 35).
, 36, 38').

(Clear) The operator listens to the index output by voice display, and if it is the one he/she intended, presses only the voice playback switch 9.

After confirming that only the audio playback switch 9 is pressed, the control unit 2 reads audio data corresponding to the audio index output immediately before from the data file l, and provides it to the audio playback unit 6. Thereby, the audio reproduction unit 6 allows the operator to reproduce and listen to the audio memo via the loudspeaker 7 (Flows 31, 35, 36, and 37).

If the output voice memo is not what the operator intended, the operator should press the voice index switch l again.
If you press the audio playback switch 9 while pressing O, the control unit 2
executes the process (4) described above to read the next index and cause the index to be output as audio.

According to the above-described embodiment f of the present invention, it is possible to quickly search and retrieve voice data such as a plurality of recorded voice memos by listening to the index displayed in voice corresponding to the data. becomes.

The above embodiment is an example in which the data filing method according to the present invention is applied to a voice memo device, but the present invention can also be applied to a file device for digital data to be processed by a computer or the like.

In this case, an input/output section including a keyboard etc. is connected to the control section 2 in FIG. 1, and the area shown as the audio data section shown in FIG. , the character code from the force device,
Digital data such as image data may be written.

That is, during data input operation, the control device 2 stores the input digital information from the input/output section in a predetermined area of the digital data section in the data file 1, and then stores the audio input from the audio input section 5 as an index. Control is performed to write the signal into the index section of the data file 1 as digitized audio data. This digital data may be input from a keyboard provided in the input/output unit, or may be input directly from another data processing device or another data file.

Furthermore, when reproducing data, the control unit 2 first sequentially outputs the audio data in the index section in the data file 1 in accordance with the operator's instructions, as in the case of the voice memo device described above. , and in response to an operational instruction from the operator during this voice index display, digital data corresponding to the index voice-displayed immediately before is read out from the data file 1 and output to the input/output section.

The output reproduction data may be visually displayed on a display unit of the input/output unit, or may be provided to another data utilization device.

By doing this, the data can be filed with a voice index added to the digital data, and the operator can search for desired data using the voice index. This makes it possible to easily input data into a device that does not have a display section.

〔Effect of the invention〕

As explained above, according to the present invention, data such as recorded audio data and digital data can be searched by listening to the index displayed and output from the audio data.
It becomes possible to search for data quickly and easily.
