Description

  The present invention relates to a voice recording device and the like.

It is an important act for those involved in creative work such as planning and research and development to memorize and remember ideas and inspirations (ideas in a broad sense) in some form on the spot. The simplest form is a writing instrument, but in recent years, small-sized recording devices that are easy to carry have been developed, and those that speak ideas and inspirations toward recording devices and store the sound as data have become widespread. It became so. For example, a voice memo function as an application of a mobile phone or PDA, an IC recorder for recording a conference / coverage, a voice memo for home message memos, and the like. Some audio data store time information and spatial information in association with each other so that it can be understood later when and when recording (see, for example, Patent Document 1).

  The speaker 1010 outputs and reproduces the stored voice data. In the drawing, the speaker is shown as a built-in speaker. However, it is preferable to provide a transparent unimorph speaker on the upper surface of the display 1008 because the size can be further reduced.

  The short-range wireless communication module 1014 is a communication module compliant with a known short-range wireless standard. The stored voice data can be transmitted by wireless communication with an external device 6 (for example, a user's personal PC).

[Description of functional block]
FIG. 2 is a functional block diagram illustrating an example of a functional configuration according to the present embodiment. As shown in the figure, the wristwatch 1000 includes a CPU 10, an operation input unit 12, a sound input unit 14, a standard time acquisition unit 16, a RAM 20, a ROM 40, a flash memory 60, a sound output unit 50, and a display. Unit 52 and communication unit 54, which are connected by a signal line 80.

  The operation input unit 12 is realized by, for example, a button switch, a lever, a dial, a touch panel, a track pad, and the like, and inputs various operations such as a menu operation and outputs an operation signal to the CPU 10. In FIG. 1, the operation input key 1012 corresponds.

  The sound input unit 14 inputs a voice (sound) and outputs a sound signal to the CPU 10. In FIG. 1, the microphone 1002 corresponds, but a connection terminal that can receive an audio signal from an external device may be provided to allow external input.

  The standard time acquisition unit 16 acquires standard time. In this embodiment, it is realized by a standard radio wave receiving antenna, a receiver, and the like, receives a standard radio wave transmitted from a predetermined standard radio wave transmitting station, and outputs the analysis result of the received radio wave to the CPU 10. In FIG. 1, the radio wave receiving antenna 1004 corresponds. For example, the communication unit 54 is connected to a communication line, and a predetermined time management server (for example, a standard protocol for providing time information “Network Time Protocol” (NTP)) is used. It is also possible to obtain a standard time by communicating with an NTP server using the network and output it to the CPU 10.

  The sound output unit 50 outputs stored sound data as sound. In FIG. 1, the speaker 1010 corresponds, but other terminals for external output may be provided.

  The display unit 52 is realized by a display element such as an LCD or an ELD, a backlight, a drive circuit, or the like, and displays and outputs characters (text), figures, images, and the like under the control of the CPU 10. In FIG. 1, the display 1008 corresponds.

  The communication unit 54 is means for performing data communication with an external device via a communication line, and can be realized by, for example, a wireless communication device, a mobile phone, a PHS terminal device, a LAN board, or the like. In FIG. 1, the short-range wireless communication module 1014 corresponds.

  The CPU 10 executes various arithmetic processes according to programs and data stored in the RAM 20, ROM 40 and flash memory 60, and controls the functions of the wristwatch 1000 in an integrated manner. For example, processing related to the function as a clock that measures the date and time, time stamp processing that embeds standard time in the voice data of the input voice so that tampering can be detected, output processing for alerting to prevent forgetting playback, A process for reproducing the stored audio data, a process for storing the reproduction history of the audio data, a process for displaying the distribution of the audio data storage date and time, and the like are executed. In FIG. 1, the CPU 10 is mounted on the control unit 1006 together with the RAM 20, the ROM 40, and the flash memory 60.

  The RAM 20 temporarily stores programs and data when the CPU 10 executes arithmetic processing. In the present embodiment, for example, an input voice data storage area 21 for storing input voice data and a date / time storage area 22 for storing the current date / time counted as a clock are provided. When the standard time acquisition unit 16 acquires standard time, the date and time storage area 22 is updated with the acquired standard time.

  The ROM 40 stores a clock program (not shown) for measuring the date and time and displaying the clock, a voice memo program 41 for causing the CPU 10 to function as a voice memo, and various graphic display data.

  The voice memo program 41 causes the CPU 10 to realize a reminder program 42 for realizing a notification function for alerting to prevent forgetting to reproduce stored voice data, and a function for displaying the distribution of the storage date and time of the voice data. And a time stamp program 44 for realizing a function of embedding the standard time at the time of storage in the input voice data so that tampering can be detected.

  The flash memory 60 is a kind of ROM that can be electrically erased and written any number of times, and is realized by, for example, a NOR flash memory. In the present embodiment, as data that is updated as needed during use, inspiration information 61 that stores voice data of a voice that the user has spoken is associated with the storage date and time.

For example, as shown in FIG. 3, the inspiration information 61 is reproduced as a storage date and time 61a, audio data 61b in which standard time information at the time of storage is embedded as a digital watermark, verification data 61c of the audio data 61b, and audio data 61b. And an unreproduced flag 61d indicating whether or not it has been stored.
The verification data 61c is data used for verification of the storage date / time of the audio data 61b and the presence / absence of falsification of the contents. Specifically, for example, the hash value of the audio data 61b, the standard time acquired when the audio data 61b is stored, and ID information (for example, a serial number) unique to the watch 1000 are set in the watch 1000 by the manufacturer. The data is encrypted using a secret key based on the public key encryption technology. Of course, the verification data 61c may be data for the purpose of detecting other alterations, and it does not matter whether it is integrated / separated from the audio data 61b.

[Description of process flow]
FIG. 4 is a flowchart for explaining the processing flow of the wristwatch 1000 according to this embodiment. The process described here is realized by the CPU 10 reading and executing the voice memo program 41, and is always in a repeated execution state. Of course, although not shown in the figure, the function as a watch is always in the execution state as well.

  The processing can be broadly divided into (1) processing related to recording, (2) processing related to alerting, (3) processing related to playback, and (4) processing related to distribution display of storage date and time of audio data. .

First, processing related to recording will be described.
When a predetermined recording operation is input from the operation input unit 12 (step S2; YES), the CPU 10 generates a voice data by sampling a voice spoken by the user and input from the sound input unit 14 for a predetermined time. And temporarily stored in the input voice data storage area 21 (step S4). The data format of audio data and the presence or absence of compression may be set as appropriate.

  Next, the standard time acquisition unit 16 acquires the standard time (step S6). Then, the CPU 10 reads and executes the time stamp program 44, and embeds the acquired standard time in the sound data stored in the input sound data storage area 21 so that tampering can be detected (step S8). Then, the CPU 10 stores the time-stamped audio data 61b and the storage date 61a in association with the inspiration information 61 (step S10). The default of the unreproduced flag 61d at this stage is a value indicating unreproduced. If the environment is such that the standard radio wave cannot be received, the time stamp process is omitted and the audio data is stored in the inspiration information 61 as it is.

  The processing related to the time stamp mentioned here can be realized by appropriately using a known digital watermark, digital signature, or time stamp. For example, the previously acquired standard time is embedded in the audio data stored in the original input audio data storage area 21 with a digital watermark. Further, the standard time obtained by embedding the standard time and calculating the hash value of the voice data, and the public key set in the wristwatch 1000 by the manufacturer, together with the standard time acquired earlier and the ID information (for example, serial number) unique to the wristwatch 1000 are obtained. It is encrypted using a secret key based on encryption technology and attached to the audio data as verification data.

  When verifying, the standard time embedded in the audio data can be confirmed by a known digital watermark technique. Further, by acquiring a public key for the wristwatch 1000 from the manufacturer based on ID information unique to the wristwatch 1000 and decoding the verification data, the standard time at which the voice data is stored can be known. Furthermore, by calculating again the hash value of the audio data to be verified and comparing it with the hash value obtained by decoding, it is possible to detect whether the audio data has been tampered with.

  The method of digital watermarking may be selected as appropriate, but a method of embedding in a sample value of data is more preferable. Compared to the method of embedding by converting to frequency components, the digital watermark itself is more easily damaged by processing audio data, so if the digital watermark at the standard time cannot be detected correctly at the time of verification, it can be regarded as falsified. .

Next, processing related to alerting will be described. The process described here is realized by the CPU 10 reading and executing the reminder program 42.
First, the CPU 10 refers to the unreproduced flag 61d of the inspiration information 61 and determines whether there is audio data 61b that has never been reproduced after storage (step S12).
If there is unreproduced audio data 61b (step S12; YES), the unreproduced audio data 61b is searched (step S14), and the elapsed time from the storage date 61a of the searched audio data satisfies a predetermined elapsed time condition. It is determined whether or not it is satisfied (step S16). In this embodiment, a plurality of conditions of “4 hours later”, “24 hours later”, “7 days later”, and “30 days later” are set as the elapsed time conditions. In particular, it is preferable that one elapsed time condition is a time (about 4 to 19 hours) in which the forgetting rate greatly decreases from the forgetting curve of the embedding house (German psychologist).

  When the elapsed time from the storage date / time 61a of the unreproduced audio data satisfies the predetermined elapsed time condition (step S16; YES), the CPU 10 displays a predetermined warning mark (reminder mark) on the display unit 52. To notify the user (step S18).

  Next, the CPU 10 stores the display start time of the reminder mark in the RAM 20 (step S20). If the current time has passed a certain time from the display start time (step S22; YES), the reminder mark display is canceled (step S24). That is, the user is accustomed to the fact that the reminder mark is displayed by the processing of steps S20 to S24, and as a result, the effect of alerting is prevented from being lost.

  For example, FIG. 5 is a diagram illustrating an example of a display screen in the alerted state in the present embodiment. As shown in the figure, for example, on the display screen of the display 1008, a date display P1, a day of the week display P2, and a time display P3 are displayed in the same manner as a conventional clock display. In step S18, the reminder mark P4 is displayed. The display form of the reminder mark P4 can be set as appropriate, but it is more preferable to set a different display form for each elapsed time condition. For example, the reminder mark P4 is displayed in blue as a display form A in “4 hours later”, and is displayed in yellow as a display form B in “24 hours later” and is always in a display state. Further, after “7 days later”, the display form C may be displayed in red and blink relatively quickly.

Next, processing related to reproduction will be described.
First, when a predetermined reproduction operation is input from the operation input unit 12 (step S26; YES), the CPU 10 displays a list of audio data 61b stored in the inspiration information 61 on the display unit 52 (step S28). At this time, for the voice data that is time-stamped, that is, for the voice data 61b that is associated with the verification data 61c, a predetermined mark indicating that it is time-stamped is attached and displayed on the list display (step S30). Similarly, a predetermined mark indicating non-reproduction is attached to the list display in the unreproduced audio data 61b (step S32). With these attached displays, the user can know at a glance which audio data is time stamped and time certification can be performed, and which audio data should be reproduced.

  Next, if a predetermined selection operation is input (step S34; YES), the CPU 10 reproduces the selected audio data 61b by the sound output unit 50, and updates the unreproduced flag 61d to be reproduced (step S36). ). Then, when a predetermined end operation is input from the operation input unit 12 (step S38; YES), the process related to reproduction is ended.

  For example, FIG. 6 is a diagram illustrating an example of a screen on which a list of audio data 61b in the present embodiment is displayed. As shown in FIG. 10A, for example, on the display screen of the display 1008, a title display P10, an operation icon P11 indicating a function assigned to the operation input key 1012, and a recording date option P12 are displayed. When the desired recording date is selected with the operation input key 1012, the selected recording date P13 and a list display P14 of audio data stored on this date are displayed as shown in FIG. The list display P14 includes, for each audio data, a file number P15, a recording time P16, an icon P17, an unreproduced mark P18 indicating unreproduced, and a time stamp mark P19 indicating time stamping. Is displayed. When the user selects desired audio data from the list display P14 with the operation input key 1012, the selected audio data is reproduced from the speaker 1010.

  Next, processing related to the distribution display of the storage date / time of audio data (referred to as “inspiration diary”) will be described. The process described here is realized by the CPU 10 reading and executing the distribution display program 43 when a predetermined operation is input from the operation input unit 12 (step S40; YES).

  First, the display unit 52 displays a display unit of time as a reference for distribution display so that it can be selected, and allows the user to select it (step S42). Then, based on the storage date / time 61a of the audio data 61b stored in the inspiration information 61, at least one of the distribution of the audio data storage date / time and the number of times the audio data is stored is displayed on the display unit 52 (step S44). And if predetermined end operation is inputted, processing about distribution display will be ended (Step S46; YES).

For example, FIG. 7 is a diagram illustrating an example of a display screen in the case of displaying on a daily basis. As shown in FIG. 6A, on the display screen of the display 1008, a title P30, an operation icon P11, and a display unit option P31 serving as a reference for distribution display are displayed.
When “daily unit” is selected, as shown in FIG. 5B, the recording date P32, the audio data list P33 stored on this date, and the total number of data P34 stored on the same day are displayed. Is displayed. Here, for example, by operating the operation input key 1012 corresponding to the operation icon P11 of “day +” or “day−”, the recording date to be displayed is changed, and on which date many inspirations are recorded. Can easily know. Of the audio data displayed in the list P33, it is preferable to display a predetermined unreproduced mark P18 attached to the unreproduced flag 61d indicating unreproduced.

  For example, FIG. 8 is a diagram illustrating an example of a display screen when displaying weekly. As shown in FIG. 6A, when “weekly” is selected in the option P31, as shown in FIG. 5B, a period display P36 in units of weeks, a date P37, The total number of data P38 stored in the day and the storage time marker P40 are displayed. In the storage time marker P40, one storage time display bar P42 is displayed for one piece of sound data, and it indicates which time of the sound data is stored in 24 hours.
