In this embodiment, a type of audio book in which the story is developed using the lines of characters, etc. is referred to as a sound story. Examples of sound stories include folk tales and fairy tales.

Furthermore, the audio book distributed by the audio file management server 20 includes information indicating areas where the user can freely insert sounds or areas where the original sounds can be replaced. shall be taken as a thing. The audio book here is an example of an audio information file. In addition, in the case of this embodiment, an area where a sound can be inserted and an area where a sound can be replaced will be explained separately, but the process of inserting a sound changes a silent area to a sound area. This is a replacement process. Therefore, in a broad sense, an area where a sound can be inserted can be said to be an area where a sound can be replaced.

An audiobook in which insertable areas or replaceable areas are defined is an example of a sound story file that can be edited. The audio book distributor determines in advance which area can be inserted or replaced. Most of the area parts here are dialogue. However, the area in which the user can insert or replace sounds does not need to include all of the lines that appear in the audio book, nor does it need to be limited to the lines of a particular character. Furthermore, the area where the user can insert or replace sounds may be a part of the narration.

The terminal 30 in this embodiment is an information device mainly operated by a user who downloads audiobooks. As the terminal 30, for example, a smartphone, a tablet terminal, an audio player, a notebook computer, etc. are used. The terminal 30 is provided with a function that allows the user to access the audio file management server 20 via the Internet 10 and download the audio book described above. However, the connection with the audio file management server 20 may be realized through another device.

Although not shown, the terminal 30 is equipped with a GPS (Global Positioning System) sensor that acquires position information, a geomagnetic sensor, an acceleration sensor, a camera that captures moving images and still images, and the like. This location information is also used to record the location where the sound was recorded.

<Functions of terminal 30>
FIG. 3 is a diagram illustrating the functional configuration of the control unit 301 that constitutes the terminal 30. The functional modules shown in FIG. 3 are realized by the CPU 311 (see FIG. 2) executing programs. Note that the functional module shown in FIG. 3 is an example of a program executed by the control unit 301. As shown in FIG. 3, the functional modules realized by this program include an audiobook acquisition module 321, an audiobook playback module 322, an audiobook editing module 323, an edited audiobook storage module 324, and a presentation screen display control module 325. , a playback control module 326.

The audiobook acquisition module 321 is a functional module that acquires audiobooks from the audio file management server 20 (see FIG. 1). The user specifies the audio book to be acquired through the operation screen of the terminal 30 (see FIG. 1). Note that the audio book may be acquired from the storage unit 302 (see FIG. 2) in addition to being acquired from the audio file management server 20. The audiobook acquisition module 321 is an example of an acquisition means.

The audiobook playback module 322 is a functional module that plays audiobooks. The reproduction of an audiobook by the audiobook reproduction module 322 includes reproduction of the original (unedited) audio and reproduction of the edited audiobook. The audiobook playback module 322 is an example of playback means.

The audiobook editing module 323 is a module that edits audiobooks. Editing of an audiobook is performed by replacing the voices of characters and narrations with voices recorded by the user. The user's voice is recorded using, for example, the microphone 306 of the terminal 30 (see FIG. 2). Note that audio books other than dialogue and narration may be included in the audio book to be edited. For example, editing may be possible in which BGM (background music) or sound effects are replaced with other sounds. Furthermore, the audio book editing module 323 can replace the audio not only for an entire audiobook, but also for each divided portion of the audiobook. For example, only the lines of a specific character or the audio of a specific scene may be replaced. The audiobook editing module 323 is an example of editing means.

Audiobook editing is not performed on the audiobook file being edited, but on a copy of such file. Therefore, when an audiobook is edited, an edited (post-edited) audiobook file is created separately from the original (before editing) audiobook file. Hereinafter, the edited audiobook file will be referred to as an edited audiobook. An edited audiobook is an example of an audio information file that has been edited. The audiobook to be edited is initially an audiobook file acquired by the audiobook acquisition module 321. After the audiobook has been edited, the edited audiobook can also be edited for further editing.

The edited audiobook storage module 324 is a module that stores the edited audiobook in a storage means such as the storage unit 302 (see FIG. 2) of the terminal 30. As mentioned above, the edited audiobook is generated as a separate file from the original audiobook, so the edited audiobook storage module 324 stores the edited audiobook separately from the original audiobook. In the saved edited audiobook file, the editing date and time (or the saving date and time) is recorded as meta information recorded in the file name, header, or the like. Edited audiobook storage module 324 is an example of storage means.

The edited audiobook storage module 324 also creates editing information for the saved edited audiobook. The editing information includes, for example, information such as the user who uttered the replaced voice (hereinafter referred to as the utterer), the age of the user who is the utterer, and the date and time of editing (or date and time of storage). Note that the editing information is automatically generated when the edited audiobook storage module 324 stores the edited audiobook, but it may be possible to edit it after the fact. The editing information is associated with the corresponding edited audio book, and is managed by being registered in, for example, a management table. Edited audiobooks associated with editing information can be kept as a history of a child's growth, for example.

The presentation screen display control module 325 is a module that generates a presentation screen for an edited audiobook and causes it to be displayed on a display means such as the display unit 303 (see FIG. 2) of the terminal 30. The presentation screen is, for example, a list of editing information of edited audiobooks arranged in the order of generation time of each edited audiobook. Further, the presentation screen may have a function as a user interface screen that accepts user operations. For example, when the user performs an operation to specify a desired edited audiobook on the presentation screen displayed on the display unit 303, the specified edited audiobook may be played. A specific example of a user interface using a presentation screen will be described later. The presentation screen display control module 325 is an example of presentation means.

The playback control module 326 is a module that receives playback instructions from the user and controls playback of the selected edited audiobook. The playback control module 326 can play the audiobook content scene by scene or line by line in response to a playback instruction. This makes it possible, for example, to reproduce only the lines of a specific character in a specific scene. The playback control module 326 is an example of playback control means.

In addition, if there are multiple edited audiobooks with audio replacements for the same audiobook or the same scene, you can combine and play the audio from the different edited audiobooks for each scene or dialogue. Also good. In this case, the edited audiobook to be played may be set by the user for each scene, dialogue, etc., or may be set automatically based on appropriate rules. In the latter case, for example, audio may be assigned to each part and played back in the order of generation, starting from the oldest edited or saved file. In this way, if the person who uttered the replaced voice is the same person, that person's voice will be used for each section of the edited audiobook in order of age (i.e., in order of age). . When audio is extracted and played from multiple edited audiobooks edited at different times, the edited audiobook storage module 324 creates a new edited audiobook in which the audio of the multiple edited audiobooks is combined. You can also save it as a file.

<Hardware configuration of audio file management server 20>
FIG. 4 is a diagram showing a configuration example of the audio file management server 20. As shown in FIG. The audio file management server 20 is realized by a computer, and includes a CPU 201 as a calculation means, a ROM 203, a RAM 202, and a storage device 204 as storage means. The RAM 202 is a main memory and is used as a working memory when the CPU 201 performs arithmetic processing. The ROM 203 holds programs and data such as pre-prepared setting values, and the CPU 201 can directly read programs and data from the ROM 203 and execute processing. The storage device 204 is a storage means for programs and data. A program is stored in the storage device 204, and the CPU 201 reads the program stored in the storage device 204 into the main storage device and executes it. Furthermore, the results of processing by the CPU 201 are stored and saved in the storage device 204. As the storage device 204, for example, a magnetic disk device, an SSD, or the like is used.

When the audio file management server 20 is configured by the above-mentioned computer, each function of these servers described below is realized by, for example, the CPU 201 executing a program. The audio file management server 20 is realized, for example, as a server built on a network. Note that these servers are not limited to the configuration of a single piece of hardware (such as a server machine), but may be configured by being distributed over multiple pieces of hardware or virtual machines.

<Function of audio file management server 20>
FIG. 5 is a diagram showing the functional configuration of the audio file management server 20. The audio file management server 20 includes an audio file management section 210, an audio file storage section 220, and a presentation screen generation section 230.

The audio file management unit 210 acquires and manages the edited audiobook and editing information that have been edited (replaced dialogue audio, etc.) on the terminal 30, along with the original audiobook. The edited audiobook acquired from the terminal 30 is stored in the audio file storage section 220.

The audio file storage unit 220 stores and saves audiobooks. The audio file storage unit 220 stores original audiobooks and edited audiobooks. As described above, the terminal 30 is provided with the edited audiobook storage module 324, which can store the generated edited audiobook, but if the storage capacity of the storage unit 302 is insufficient, the external storage It can be stored in the audio file storage unit 220 as a means. In addition, by backing up edited audiobooks generated on the terminal 30 to the audio file storage section 220 of the audio file management server 20, even if the device (hardware) of the terminal 30 is changed, the edited audiobooks generated on the terminal 30 can be backed up. Edited audiobooks can be carried over.

The presentation screen generation unit 230 generates a presentation screen for the edited audiobook in response to a request from the terminal 30 and sends it back. When an edited audiobook is played back on the terminal 30, the presentation screen display control module 325 generates a presentation screen for presenting the edited audiobook and receiving a selection of a playback target. Here, if the edited audiobook and editing information are managed by the audio file management unit 210, the presentation screen generation unit 230 of the audio file management server 20 generates the presentation screen instead of the presentation screen display control module 325. It's okay. In this way, even if the edited audiobook and editing information are backed up and then deleted on the terminal 30, the presentation screen can be acquired from the audio file management server 20 and displayed on the terminal 30. can do.

<Playback operation of edited audiobooks>
Next, the reproduction operation of an edited audiobook will be explained. Here, it is assumed that the terminal 30 stores the edited audiobook in its own device using the edited audiobook storage module 324 and generates a presentation screen using the presentation screen display control module 325.

FIG. 6 is a flowchart showing the operation of playing an edited audiobook by the terminal 30. Assume that in the initial state, a function selection menu screen is displayed on the display unit 303 of the terminal 30. Although not particularly illustrated, the menu screen is configured to display functions such as selecting and playing audio book content, setting attributes, etc., and the user can select them by operating on the screen. With this menu screen displayed, the user operates the operation reception unit 304 to select a desired function (S601).

When playback of an audiobook is selected on the menu screen, the presentation screen display control module 325 displays an audiobook presentation screen, which is displayed on the display unit 303 of the terminal 30 . The presentation screen 330 displays the original audiobook and the edited audiobook for each audiobook content.

FIG. 7 is a diagram showing an example of a presentation screen. In the example shown in FIG. 7, the presentation screen 330 is provided with a file information display area 331 and a button object 332. The file information display area 331 displays a list of original audiobooks and edited audiobook files saved by the edited audiobook storage module 324. In the example shown in FIG. 7, a plurality of audiobook files are shown for each of the audiobook contents "Folktales 1" and "Folktales 2." Note that in Figure 7, the original audiobook and the edited audiobook are not explicitly displayed separately, but the original audiobook is displayed at the top of each content, and the original audiobook is displayed at the top level of each content. They may be distinguished by attaching a mark indicating this.

For each file, information on the following items is shown: "title", "name", "age", and "date of recording". “Title” indicates the title of the audiobook content. The "name" indicates the name of the user who is the main utterer for voice replacement in the edited audiobook. "Age" indicates the age of the user who is the utterer. The “recording date” indicates when the edited audiobook was edited. This information is obtained from editing information associated with each file. With this information, the user can identify who edited the edited audiobook and when (at what age) the file was edited. The presentation screen 440 also serves as a user interface screen, and the user performs an operation (such as a mouse click) to designate a field in which a desired file is displayed on the file information display area 331 to specify a reproduction target. The button object 332 labeled "Determine" is an object for determining the file to be played. The button object 333 labeled "Specify Scene" is an object for moving to a selection screen for selecting a scene to be played from among the scenes that are part of the content of the edited audiobook.

FIG. 8 is a diagram showing an example of a selection screen. In the example shown in FIG. 8, the selection screen 340 is provided with a scene specific display 341, an editing information display area 342, and a button object 343. The selection screen 340 also serves as a user interface screen. The scene specific display 341 is a band area in which the story is divided into a plurality of scenes and the scenes are arranged in chronological order. When the user specifies a desired scene on this scene specifying display 341, if editing has been performed on that scene, an editing information display area 342 is displayed, and editing information for the corresponding part is displayed. In the example shown in FIG. 8, the left end of the scene specific display 341 (the third scene toward the right from the first scene of the story) is specified, and editing information is displayed from the specified scene position by a pull-down display. Area 342 is displayed.

In the editing information display area 342, for the specified scene, the "name" of the user who is the main speaker for voice replacement, the "age" of the user who is the main speaker, and the time when the edited audiobook was edited. Information such as "date of recording" is shown. The user performs an operation (mouse click, etc.) to specify a field in which desired editing information is displayed on the display of the editing information display area 342, and specifies the audio (data) to be played back in the specified scene. The button object 343 labeled "Determine" is an object for determining the audio to be played for the scene specified by the operation on the scene specifying display 341. In the example shown in FIG. 8, only one scene is specified, but the audio to be played back can be specified for each scene.

Returning to FIG. 6, one edited audiobook (described as "edited file" in the diagram) is specified on the presentation screen 330 (see FIG. 7) (YES in S602), and played on the selection screen 340 (see FIG. 8). When a location (scene) and audio are specified (YES in S603) and the "Confirm" button object 343 is operated, the playback control module 326 specifies the audio to be played at the playback location in the edited audiobook. is received (S604), and an instruction to reproduce the audio of the corresponding part is transmitted to the audiobook reproduction module 322.
