Description

The present invention relates to a speech information replacement system and program.

Conventionally, there is an after-recording (so-called after-recording) technology for recording dialogue, music, etc., in accordance with the screen of a story such as a movie.
For example, Patent Literature 1 describes an example of a device for genuinely experiencing a voice actor while enjoying a sense of unity with a story. This device has a function of reproducing voices other than those of the cast selected by the player, and a function of displaying only the telop corresponding to the lines of the cast selected by the player at the timing when the cast selected by the player speaks. ing. Therefore, the player can experience dubbing just by speaking in time with the telop. Since the display screen displays moving images such as animation and drama, the player can enjoy a sense of unity with the story.

JP 2006-346284 A

The apparatus described above distinguishes between the cast selected by the player and the cast not selected by the player, and controls the reproduction of lines and the output of telops for each. For this reason, if the player does not utter the lines of the cast selected by the player, the lines of the corresponding part are missing.
Post-recording technology is also applied to audiobooks that record folk tales. Audiobooks can be enjoyed in a variety of ways, depending on the age of the child. For example, it is heartwarming to see a small child uttering an interesting line or sound in sync with the reproduced sound, and the recorded voice of the child becomes a pleasant memory for the parent and child. In addition, if the child is a little older, it is possible to leave a record of the child's growth by intentionally changing the lines and uttering them. In this way, the recording of the child's voice serves as a record of the child's growth as well as a family memory.

By the way, audiobooks as educational materials have a button for instructing voice recording, but there is no button for canceling the recording operation after the recording has started, or when canceling the recording operation, the sound recorded before the cancellation is automatically canceled. There is no function, etc., for deleting data automatically. For this reason, the user needs to open the editing screen after the fact, search for unnecessary recordings, and delete unnecessary recordings. In addition, if unnecessary recordings remain stored, it becomes a hindrance to finding the desired recordings, which contributes to a decrease in the efficiency of the entire voice replacement work.
In addition, audiobooks have a function to notify the user of replaceable lines, and the user can check the positional relationship of replaceable regions in the audiobook, the number of replaced regions, etc. No mechanism exists. Therefore, it is not easy to check the area where the replacement voice is not recorded. As a result, there is a need for a mechanism that increases the efficiency of the overall voice replacement task by the user.

SUMMARY OF THE INVENTION It is an object of the present invention to efficiently replace the original voice in the replacement region with an arbitrary sound and to check the contents of the replacement.

<Functional Configuration of Terminal 30>
FIG. 3 is a diagram for explaining the functional configuration of the control unit 301 that configures the terminal 30. As shown in FIG.
The functional modules shown in FIG. 3 are realized through program execution by the CPU 311 (see FIG. 2). Note that the functional modules shown in FIG. 3 are examples of programs executed by the control unit 301 .

One of the programs shown in FIG. 3 includes an audiobook acquisition module 321 that acquires audiobooks from the audio file management server 20 (see FIG. 1). The audiobook to be acquired is designated by the user through the operation screen of the terminal 30 (see FIG. 1). Audiobooks may be obtained from the storage unit 302 (see FIG. 2) in addition to being obtained from the audio file management server 20 . The audiobook acquisition module 321 is an example of acquisition means.

One of the programs shown in FIG. 3 is an audiobook playback module 322 that plays audiobooks.
In the case of this embodiment, there are two types of audiobook playback by the audiobook playback module 322: playback of the original audio and playback of the edited audiobook. (See FIG. 2). Audiobook playback module 322 is an example of playback means.

One of the programs shown in FIG. 3 includes a replaceable area presentation module 323 that presents to the user an area portion of the audiobook that can be replaced or inserted with sounds collected by the user.
Here, the replaceable area presentation module 323 distinguishes between replaceable and non-replaceable lines in the manner of displaying lines and the like displayed on the display unit 303 (see FIG. 2).
For example, lines that cannot be replaced are displayed in a standard thickness and size, while lines that can be replaced are displayed in bold. For example, lines that cannot be replaced are displayed in black characters, while lines that can be replaced are displayed in red characters. Further, for example, lines that cannot be replaced are not marked, whereas lines that can be replaced are additionally displayed with a characteristic mark.
Also, the replaceable area etc. presentation module 323 displays on the display unit 303 a mark or the like indicating that in the area portion where the sound collected by the user can be inserted.
Alternatively, the replaceable region portion or the insertable region portion may be presented by outputting a predetermined specific sound. For example, a buzzer or the like may be used to notify the corresponding position.

One of the programs shown in FIG. 3 has a replacement instruction reception module 324 that receives a replacement instruction from the user.
In the case of the present embodiment, operation of the record button is used to instruct replacement. When the replacement instruction is accepted, the output of the original voice is stopped, and the recording of the voice and the selection of pre-recorded sound material become possible. A record button is an example of a second button.
It should be noted that separate buttons may be prepared for recording voice on the spot and for selectively specifying sound material, or the operation can be performed by tapping the record button once or twice. You may enable it to switch. In the case of selectively designating sound materials, the reproduction of the audiobook is also stopped until a selection instruction is received. To stop recording, use the operation of the stop button. A stop button is an example of a third button. Of course, it is also possible to have a mechanism for automatically stopping the recording after the end of the playback time of the original voice of the line to be replaced.

One of the programs shown in FIG. 3 has a sound material insertion reception module 325 that receives a sound material insertion instruction from the user.
In the case of this embodiment, the operation of the record button is also used to issue an instruction to insert a sound material. Even when an instruction to insert a sound material is received, a state is entered in which recording of voice or the like and selection of pre-recorded sound material are possible.
As for the insertion of sound materials, there are cases where voices and the like are recorded on the spot and cases where sound materials are selectively instructed. The method of operation is the same as in the case of the replacement instruction.
Hereinafter, when replacing and inserting sound materials are collectively referred to as "replacement, etc."

One of the programs shown in FIG. 3 includes an edited audio book for recording an audiobook edited by replacing or inserting sound materials (hereinafter referred to as an "edited audiobook") in the storage unit 302 (see FIG. 2). There is a book storage module 326 .
Edited audiobooks are created separately from unedited audiobooks. Therefore, the pre-edited audiobook is preserved in its pre-edited state. In the case of this embodiment, the date and time of saving, etc. are automatically inserted into the file name of the edited audiobook. A plurality of edited audiobooks saved in this way can be left as a history of a child's growth. However, the file name may be edited after the fact.

One of the programs shown in FIG. 3 includes a support information presentation module 327 that supports the user in replacing voices and the like.
The support information presentation module 327 in this embodiment has a function of presenting information on the display unit 303 to support progress such as voice replacement by the user, in addition to the operation of the recording button and the recording stop button.
"Information to support the progress of voice replacement by the user" in the present embodiment is not information for directly instructing replacement, etc. like the record button, but contributes to efficiency of work related to replacement, etc. Information. In other words, it refers to information that contributes to grasping the progress of the entire work such as replacement and promoting the progress. Efficiency here includes the reduction of the man-hours required to achieve the desired effect and the reduction of the time required for the work.

In the case of this embodiment, the information for assisting the progress of voice replacement by the user includes, for example, a button (hereinafter referred to as a "skip button") for instructing skipping of voice replacement for replaceable regions, a replaceable region and the number of regions that have been replaced, the position of the replaceable region and the replaced region on the time axis corresponding to the original audio, and the replacement of the audio even once during the playback of the original audio Prepare a save destination selection screen that is displayed when
By presenting these pieces of information, it is possible to improve the efficiency of work related to progress, such as voice replacement, by the user.
The support information presentation module 327 here is an example of presentation means. Also, the skip button is an example of the first button.

<Example 1 of processing operation>
Here, processing operations realized by functional modules other than the support information presentation module 327 (see FIG. 3) among the functional modules provided in the terminal 30 (see FIG. 1) will be described.

<Edit audiobook>
FIG. 4 is a flowchart illustrating exemplary processing operations performed when editing a downloaded audiobook. Note that S in the figure means a step.
When the control unit 301 (see FIG. 2) detects a specific operation by the user, it accepts selection of an audiobook (step 1). An example of a specific action is a prompt for selection on a screen listing downloaded audiobooks.
Upon receiving the selection instruction, the control unit 301 determines whether or not the selected audiobook has an area that can be replaced (step 2). The presence or absence of replaceable regions can be identified from information attached to the audiobook.

If a negative result is obtained in step 2, the control unit 301 accepts the instruction to play the audiobook and starts playing the audiobook (step 3).
When playback of the audiobook is started, the control unit 301 determines whether playback is finished (step 4).
As long as step 4 yields a negative result, control unit 301 continues playing the audiobook. In this case, since there is no area where replacement or the like is possible, the audiobook audio is reproduced as it is.
A positive result in step 4 terminates the audiobook playback.

On the other hand, if a positive result is obtained in step 2, the control unit 301 accepts the instruction to play the audiobook and starts playing the audiobook (step 5).
After that, the control unit 301 determines whether or not the position being reproduced is in an area where replacement or the like is possible (step 6).
While a negative result is obtained in step 6, the control unit 301 repeats the determination.
If a positive result is obtained in step 6, the control unit 301 presents to the user that it is an area where replacement or the like is possible (step 7).

Subsequently, the control unit 301 (see FIG. 2) determines whether or not an instruction such as replacement has been received (step 8).
In the case of this embodiment, the control unit 301 determines whether or not the operation of the record button has been detected.
If step 8 yields a negative result, control unit 301 returns to step 6 to continue playing the audiobook.
On the other hand, if a positive result is obtained in step 8, the control unit 301 accepts the sound material (step 9).
After that, the control unit 301 determines whether or not the reproduction is finished (step 10).
While a negative result is obtained in step 10, the control unit 301 returns to step 6 and continues playing the audiobook.

Examples of display screens corresponding to steps 1 to 10 are shown in FIGS.
FIG. 5 is a diagram illustrating examples of screens at time T1 when an audiobook is selected and time T2 when an audiobook reproduction instruction is received.
Time T1 corresponds to step 1 and time T2 corresponds to step 5. FIG.
On the screen at time T1, "folk tales 1", "folk tales 2", and "folk tales 3" are displayed as examples of selectable audiobooks, and select buttons are displayed adjacent to each of them. In addition, in FIG. 5, a check mark is attached to the selection button of "old tale 1". The screen after the OK button 332 is operated in this state is the screen at time T2.

In the case of FIG. 5, a title 333, a time axis 334, and a slider 335 representing a playback position are displayed in the upper part of the screen at time T2. At time T2, reproduction has not started, so the slider 335 is positioned at the left end, which is the origin. Note that the slider 335 can also be used to move the playback position.
Three types of buttons are arranged in the lower part of the screen at time T2. A button 336 is a playback button for the original voice or the like. A button 337 is a button used by the user to instruct, for example, replacement of collected sound materials. In the case of FIG. 5, button 337 is the record button. Button 338 is a button used to instruct playback of the edited audiobook. In the case of FIG. 5, button 338 is a repeat play button.
In FIG. 5, the user is operating the leftmost button 336 .

FIG. 6 is a diagram illustrating an example of a screen at time T3 when an area that cannot be replaced is reproduced and an example of a screen at time T4 when an area that can be replaced is reproduced.
Time T3 corresponds to a negative result in step 6, and time T4 corresponds to step 7.
In the case of FIG. 6, "old tale 1" is the fairy tale "Little Red Riding Hood".
On the screen at time T3, time has already passed since the playback started, so the slider 335 has moved to near the center of the time axis 334 . At time T3, there is a line 339 of the character Little Red Riding Hood, and the terminal 30 outputs the corresponding voice. The line 339 here is "Oh, grandmother, what a big book."
In the case of this embodiment, the speech 339 at time T3 is registered as a speech that cannot be replaced. Therefore, on the display screen of the terminal 30, a character string representing the content of the dialogue 339 is displayed with a reference thickness and size.

Time T4 is immediately after time T3. On the screen at time T4, there is a line 340 of the character wolf, and the corresponding voice is output. The line 340 here is "I hope you can get a good hold of it."
In the present embodiment, the line 340 at time T4 is registered as a line that can be replaced. Actually, in FIG. 6, the terminal 30 outputs a voice corresponding to the line 340 .
A line 340 is displayed on the display screen of the terminal 30 in such a manner as to inform the user that replacement or the like is possible. In the case of FIG. 6, the line 340 is changed to bold characters, and at the same time, an elliptical mark 341 is added behind the line 340 . The presence of the mark 341 or the like allows the user to know that the dialogue is replaceable.

FIG. 7 is a diagram illustrating an example of a screen displayed when a replacement instruction is received. In FIG. 7, parts corresponding to the screen at time T4 in FIG. 6 are shown with reference numerals.
Here, the user is operating button 337 . By the user's operation of the button 337, the terminal 30 enters a state of waiting for the input of the sound material. In FIG. 7, it is assumed that the microphone 306 (see FIG. 2) of the terminal 30 records a child's voice. Therefore, the output of the voice corresponding to the dialogue 340 is stopped. The reason why the output of the voice from the terminal 30 is stopped is to prevent the voice output from the terminal 30 from being recorded together with the child's voice.
It should be noted that audio output from the terminal 30 is stopped after the button 337 is operated. In other words, until the button 337 is operated, the terminal 30 outputs the voice corresponding to the replaceable dialogue 340 as shown in FIG.
In the example of FIG. 7, the child is uttering a line 340 of a wolf, and this voice is recorded on the terminal 30 .

FIG. 8 is a diagram illustrating another example of a screen displayed when a replacement instruction is received. In FIG. 8, parts corresponding to those in FIG. 7 are shown with reference numerals corresponding thereto.
The screen shown in FIG. 8 is also common to FIG. 7 in that the dialogue 340 is replaced at time T4, but differs from FIG.
In the case of FIG. 8, the fact that replacement is possible is indicated by a character string 341A instead of the mark 341 (see FIG. 7).
In addition, a list 342 of sound material candidates recorded in the past using the terminal 30 or the like is displayed in the middle and lower part of the screen. In the case of FIG. 8, there are three candidates. The list 342 includes a file name corresponding to each candidate, a selection button, and a playback button used to confirm the content.

The candidate file names shown in FIG. 8 include information on the date and time of recording and the cast, making it possible to identify the content of the sound. In addition, serial numbers are added to the end of the file names to distinguish the lines of the same cast recorded on the same day. For example, the first candidate is the sound material recorded at 19:06 on March 7, 2019, and it can be seen that it is the first line of the wolf. Note that the serial number may mean the order of recording on the recording date.
As in the example of FIG. 8, when the file name contains information about the cast, the terminal 30 selectively displays sound materials related to the cast corresponding to the dialogue 340 in the region where the user instructs replacement. is also possible.
In addition, when the serial number represents a replaceable region portion, the terminal 30 can selectively display pinpoint related audio materials.

Although the file names shown in FIG. 8 contain the information of the cast, the information indicating the recording location of the sound material may be included instead of or together with the cast. For example, home, park, etc. may be included in the file name. In addition, the file name may include information indicating whose voice it is and the age of the child at the time of recording. However, these pieces of information may be included only in the information attached to the file.
In the example of FIG. 8, a check mark is attached to the selection button of the second candidate.
When the decision button 344 is operated in this state, the replacement of the area portion to be edited is completed. Note that when the return button 343 is operated, for example, the screen returns to the screen before editing.

FIG. 9 is a diagram illustrating an example of a screen displayed in an area where sound can be added. In FIG. 9, parts corresponding to the screen at time T4 in FIG. 7 are shown with reference numerals.
The screen of FIG. 9 corresponds to time T5, which is different from any of the above.
Time point T5 in this embodiment is a region portion where sound insertion (that is, sound addition) is possible. Therefore, there is no dialogue or the like.
In FIG. 9, an explanation 346 and a characteristic mark 345 express that sound can be added.
At this time point T5, the user or child who wants to add a sound operates the button 337 .

FIG. 10 is a diagram illustrating an example of a screen displayed when an instruction to add sound is received. In FIG. 10, the parts corresponding to those in FIG. 8 are indicated by the reference numerals.
In the case of FIG. 10, a character string 341B indicates that sound can be inserted.
In addition, a list 347 of sound material candidates recorded in the past using the terminal 30 or the like is displayed in the middle and lower part of the screen. In the case of FIG. 10, there are three candidates. List 347 includes a file name corresponding to each candidate, a selection button, and a playback button used to confirm the content.
The file name in FIG. 10 contains information on the date and time of recording and the recording location. For example, the first candidate is the sound material recorded in the park at 14:23 on March 7, 2019.
In the example of FIG. 10, a check mark is attached to the selection button of the first candidate.
When the decision button 344 is operated in this state, the insertion of the sound material into the area to be edited is completed. Note that when the return button 343 is operated, for example, the screen returns to the screen before editing.
As in the case of FIG. 9, when the button 337 is operated, the sound on the spot may be recorded and the sound recorded in the corresponding area may be inserted. The audiobook with the inserted sound is recorded in the storage unit 302 (see FIG. 2) as an edited audiobook.

11A and 11B are diagrams for explaining the relationship between a region in which replacement or the like is possible and a region for which the user has actually instructed the replacement or the like. (A) shows the arrangement of predetermined replaceable regions in the audiobook, and (B) shows the regions actually instructed by the user to be replaced.
In the case of FIG. 11, there are 10 replaceable areas, one of which the user instructs to insert a sound material, and two of which the user instructs to replace the sound material. The original voice and the like remain as they are in the rest of the replaceable areas.

It should be noted that it is possible to determine the area in which replacement or the like is possible regardless of the lines of a specific cast. Therefore, the child can selectively replace only the lines that interest him/herself. With this feature, the audiobooks of this embodiment can generate a number of edited audiobooks in the course of the child's growth. For example, when the child is small, only the sounds of animals are replaced, but as the child grows, an edited audio book in which longer lines are replaced can be recorded and left. In other words, it becomes possible to record the process of growth. In addition, it becomes possible to record changes in interest accompanying growth as differences in regions for which replacement or the like is instructed.
Incidentally, in the case of audiobooks according to the present embodiment, regions that can be replaced or the like are determined in advance, so that the user or a child can concentrate on the sounds to be collected.

Returning to the description of FIG.
When the audiobook has finished playing (ie, a positive result is obtained in step 10), the control unit 301 (see FIG. 2) determines whether there has been a replacement or the like during playback (step 11).
If a negative result is obtained in step 11, the control unit 301 terminates the process. This is because it is the same as playing back an audiobook that does not have a replaceable area.

On the other hand, if a positive result is obtained in step 11, the control unit 301 gives a file name to the edited audiobook reflecting the result of editing such as replacement and saves it (step 12). In the case of this embodiment, the file name of the edited audiobook consists of the original file name and the editing work date.
In this embodiment, once the edited audiobook has been saved, the edited audiobook that has just been saved is automatically played once. This reproduction is for confirmation of the saved contents. When the repeat playback button 338 (see FIG. 5) is operated, the edited audiobook is played back repeatedly.

<Example 2 of processing operation>
Processing operations unique to the support information presentation module 327 (see FIG. 3) among the functional modules provided in the terminal 30 (see FIG. 1) will be described below.
The following description focuses on the screen displayed on the display unit 303 (see FIG. 2) of the terminal 30 during playback of an audiobook in which replaceable areas are set.
In addition, in Example 1 of the processing operation, "Little Red Riding Hood" is used as an example of a fairy tale, but "Big Turnip" is used as an example of a fairy tale below.

<Display at the start of playback>
FIG. 12 is a diagram for explaining a display example of a screen immediately after starting playback of an audiobook containing replaceable regions.
FIG. 12 shows a portion of the image displayed on the display unit 303. FIG. The screen display shown in FIG. 12 corresponds to step 5 (see FIG. 4).
In the case of FIG. 12, a display section 400 is provided in the center of the display unit 303 to display the content of the story corresponding to the audiobook. A title 401 is displayed on the display unit 400 . In the case of the present embodiment, the content of the story is displayed on the display unit 400 in the form of still images or moving images. However, the content of the story may be displayed in characters on the display unit 400 .
A time axis 410 indicating the playback time of the story is arranged at the bottom of the display section 400 . A time axis 410 shows a slider 411 representing the current playback position. In the case of FIG. 12, the slider 411 is positioned at the left end corresponding to the head position because the playback is just started.

In the case of FIG. 12, the area where the voice can be replaced is represented by a balloon 412 represented by a picture of a microphone. Ten balloons 412 are arranged along the time axis 410 . The display of the microphone picture balloon 412 is realized by the support information presentation module 327 (see FIG. 3).
By displaying balloon 412, the user can know that there are ten replaceable regions.
In the case of this embodiment, the color and shape of balloon 412 change depending on whether or not it is a recorded area. When the color and shape of the speech bubble 412 change depending on whether or not the area has been recorded, the user can immediately grasp which area's dialogue has been recorded or has not been recorded. If only the number of recorded areas is displayed, the recorded position cannot be known, but if the color and shape of the balloon 412 changes, the recorded position can be confirmed.

The display of balloons 412 in FIG. 12 indicates that voice replacement has not been completed. This can also be confirmed by the display of counter 420 arranged on the left side of display unit 400 . The counter 420 is composed of a microphone mark and a count value. The count value consists of a denominator that represents the total number of replaceable regions and a numerator that represents the number of regions in which speech was recorded.
In the case of FIG. 12, the numerical value of the denominator is "10" and the numerical value of the numerator is "0". The display of this counter 420 is also realized by the support information presentation module 327 .

From the display of the counter 420, the user can easily know that there are 10 replaceable regions and that the number of voice-recorded regions is 0.
Note that the numerical value of the numerator is incremented each time the number of regions in which sound is recorded increases. An increase in the number of voice-recorded areas can be expected to give the user a sense of accomplishment and increase their desire to record.
Incidentally, the numerical value of the numerator is counted in units of area. Therefore, even if the number of recordings corresponding to a certain region is plural, the numerical value of the numerator is counted as "1".

In addition, the user can easily predict whether or not the replaceable area is about to be reproduced, based on the relationship between the position of the slider 411 and the position of the balloon 412 . By being able to know in advance that the replaceable region is about to be played, the user can start recording without panicking.
As a result, it is possible to reduce the number of operations such as returning the playback position in order to record the voice in the replaceable area, and improve the workability of the replacement.

FIG. 13 is a diagram for explaining a display example of a screen when playback of an audiobook that has already been recorded in part of the replaceable area is selected. In FIG. 13, parts corresponding to those in FIG. 12 are shown with reference numerals.
The screen shown in FIG. 13 also represents the state immediately after the start of playback of an audiobook containing replaceable regions. The difference is that the display color of the areas other than the positions indicated by the fifth and seventh balloons 412 from the top is changed, and the display of the counter 420 is changed to "8/10".

By confirming the above display, the user can immediately understand that there are recording records in the 1st to 4th, 6th, and 8th to 10th areas from the top.
In addition, when it is found that there is an area in which no replacement voice is recorded, the user can be motivated to pinpoint voice recording in the corresponding area.
By the way, with the display described in the processing operation example 1, the user cannot know whether or not the replacement voice is recorded in the area. Therefore, the user records the sound in the region of interest each time the audiobook is played.

On the other hand, in the case of FIG. 13, since the area where the sound is not recorded can be pinpointed, just by tapping the corresponding balloon 412 on the screen, the recording of the sound in the corresponding part can be started.
FIG. 14 is a diagram illustrating how the fifth balloon 412 from the top is tapped with the index finger. In FIG. 14, the parts corresponding to those in FIG. 13 are indicated by the reference numerals.
After the user taps the balloon 412, the image of the scene corresponding to the fifth balloon 412 from the top is displayed on the display unit 400, and the reproduction of the audiobook is resumed. Therefore, the user can efficiently record the desired voice.
In the case of this embodiment, the jump destination when balloon 412 is tapped is a position slightly before the position corresponding to tapped balloon 412 . In this case, since playback does not start suddenly from the tapped balloon 412, there is ample time to operate the record button. However, you may jump to the position corresponding to the balloon 412 tapped.
Although it is possible to jump the playback position by moving the slider, if the speech balloon 412 is not displayed, the search for the desired position becomes troublesome.

Jumping to the position corresponding to balloon 412 may be conditional on a double tap. In this case, a single tap may be used to display all or part of the dialogue corresponding to balloon 412 .
By displaying all or part of the dialogue, it is possible to confirm in advance whether it is the dialogue to be recorded. If the dialogue can be confirmed in advance, there is no need to repeatedly jump to the playback position for the purpose of searching for the dialogue desired to be recorded, and the voice replacement work can proceed efficiently.
Note that the balloon 412 that is tapped to jump the playback position is not limited to an area where no sound is recorded. That is, it is also possible to tap the balloon 412 corresponding to the area where the voice has already been recorded. This is because there are cases where another voice is desired to be recorded even in an area where voice has already been recorded.

<Display during playback of replaceable area>
FIG. 15 is a diagram for explaining a display example of a screen immediately after starting reproduction of a replaceable area. The screen display shown in FIG. 15 corresponds to step 7 (see FIG. 4).
In the case of FIG. 15, the color tone of the entire screen changes, indicating that it is a replaceable area. In addition, in Example 1 of the processing operation, the background and notation of the corresponding dialogue 340 (see FIG. 7) were changed. In the case of FIG. 15, changing the color tone of the entire screen makes it easier for the user to notice that the area can be replaced. However, it is also possible to change only the display of the corresponding speech 340 (see FIG. 7), as in the processing operation example 1. FIG.

On the screen shown in FIG. 15, a recording button 402, a message 403 prompting an operation, and lines 430 are displayed. Further, on the right side of the display unit 400, a button 441 for closing the screen, a help button 442, and a skip button 443 are arranged downward from the top.
In the case of FIG. 15, the message 403 is written as “press the button”, and the user is requested to operate the record button 402 . Recording is started when the record button 402 is operated.
In the line 430, the color of the notation of 'big, sweet,' in the second line is different from that in the upper and lower lines, indicating that the line in the second line is to be recorded. Since the first line is being reproduced, it is highlighted, and the luminance of the second and third lines where reproduction will start from now on is displayed lower than that of the first line.

In the case of this embodiment, the screen shown in FIG. 15 is displayed for each replaceable region, but the user may not wish to replace the corresponding line.
Even in this case, recording does not start unless the recording button 402 is operated, but it is possible that the user does not like the fact that the still image or moving image displayed on the display unit 400 is hidden by the recording button 402 or the message 403 . be done.
A skip button 443 is used in such a case.
FIG. 16 is a diagram for explaining how the skip button 443 is operated during playback of a replaceable area. In FIG. 16, the parts corresponding to those in FIG. 15 are indicated by the reference numerals. FIG. 16 illustrates how the user taps the skip button 443 with his finger.
If the operation of skip button 443 is detected, a negative result is obtained in step 8 (see FIG. 4). When the skip button 443 is operated, a negative result is output in the process of step 6 until the reproduction of the corresponding area is completed.
FIG. 17 is a diagram for explaining a display example of the screen after the skip button 443 is operated. In the case of FIG. 17, the display screen returns to the display of the original image. Therefore, the user can enjoy the images. Of course, the reproduction of the original voice is continued.

By the way, if you want to stop recording the voice, it is not always before you start recording. For example, it is conceivable that recording is started by operating the recording button 402 (see FIG. 15), but the recording is stopped because the child dislikes it. This situation will be described below with reference to FIGS. 18 to 20. FIG.
FIG. 18 is a diagram for explaining how the record button 402 is operated during playback of a replaceable area. In FIG. 18, the parts corresponding to those in FIG. 15 are indicated by the reference numerals. FIG. 18 depicts the user tapping the record button 402 with his or her finger.

FIG. 19 is a diagram for explaining a display example of a screen displayed after the recording button 402 is operated. In FIG. 19, parts corresponding to those in FIG. 18 are shown with reference numerals corresponding thereto. The screen display shown in FIG. 19 corresponds to step 9 (see FIG. 4).
By operating the record button 402, the display unit 400 displays a microphone-shaped icon 404 and a message 403A indicating that recording is in progress. The message 403A is written as "Rokuonchu...". Also, the notation of the second line of the dialogue 430 is changed according to the timing of utterance of the dialogue. In the example of FIG. 19, the notation up to "large" is changed to indicate the part to be uttered.

Normally, the voice of the user would be recorded in this situation, but as described above, children may dislike vocalization.
When the child dislikes vocalization and the user operates the recording stop button, the sound after tapping the recording button 402 is saved in the terminal 30 . However, the stored sounds are the result of incomplete recordings or sounds that were never intended to be used. For this reason, the user needs to search for and delete the corresponding sound again after the audiobook has been played.
However, such work is troublesome and burdens the user.

FIG. 20 is a diagram for explaining how the skip button 443 is operated during recording. In FIG. 20, parts corresponding to those in FIG. 19 are shown with reference numerals corresponding thereto. FIG. 20 illustrates how the user taps the skip button 443 with his finger.
The screen shown in FIG. 20 corresponds to forced termination of step 9 (see FIG. 4).
When the skip button 443 is operated, the recording is stopped and the display is switched to the screen shown in FIG. After that, the reproduction of the original voice is resumed. It should be noted that when the skip button 443 is operated, the original voice may be resumed with the entire dialogue, or with the dialogue that has not been reproduced when the skip button 443 is tapped.
In the case of this embodiment, when the skip button 443 is operated, the sound recorded after the record button 402 is operated is also automatically erased. Therefore, it is possible to save the trouble of deleting the voices that are not used for replacement after the audiobook has been played back. In this sense, it is possible to improve the efficiency of voice replacement work.
As described above, the skip button 443 functions as a button for canceling or invalidating execution of the function.

In the case of the present embodiment, once the skip button 443 is operated, the user is prompted to record as shown in FIG. No display is performed.
If you skip recording because your child doesn't like it, there is a high possibility that you won't be able to record even in the recordable area from the next time onwards. It is for the sake of becoming.
Note that even when the display prompting recording is not displayed, when the user taps the speech balloon 412 of the dialogue to be recorded, the screen prompting recording is displayed again.
Also, the area affected by the operation of the skip button 443 can be limited to the area where the skip operation is detected. It is desirable that the switching of the influence of the skipping operation be switched by setting the application program.

By the way, when a predetermined time elapses after the recording button 402 is operated, the display of the display unit 400 switches to a screen for stopping recording.
FIG. 21 is a diagram for explaining a display example of the screen after a predetermined time has passed since the recording button 402 was operated. In FIG. 21, the parts corresponding to those in FIG. 19 are indicated by the reference numerals.
The screen shown in FIG. 21 displays a stop button 406 and a message 407 representing an operation requested from the user. A message 407 indicates an operation to end the recording, saying "Press the button when the recording is over."

It is also possible to employ a mechanism in which recording is automatically terminated at the timing at which the speech to be recorded finishes being reproduced. However, if such a mechanism is adopted, the recording state continues even after the user has finished speaking, and even unintended sounds may be recorded as replacement voices. In that case, the user needs to re-record or delete the recorded sound.
On the other hand, in the case of the present embodiment, operation of stop button 406 terminates recording, so the possibility of unintended sound being recorded can be reduced.

In the case of the present embodiment, the recorded voice is reproduced so as to replace the entire original voice of the corresponding line regardless of the recording time. That is, even if the recording time until the user operates the stop button 406 is shorter than the playback time of the original voice of the replaceable dialogue, part of the original voice is not played back. Therefore, there is no need to re-record, and the workability of replacement is improved.

FIG. 22 is a diagram illustrating a display example of a screen displayed after the stop button 406 (see FIG. 21) is operated. In FIG. 22, parts corresponding to those in FIG. 12 are shown with reference numerals.
In the case of this embodiment, the screen 450 is displayed each time the recording in the replaceable area is completed. On the screen 450, messages such as "You've done it!", "You've made it to the Rokuon!", "Let's try the next Rokuon challenge!" are displayed. The screen 450 is displayed for the purpose of increasing the child's motivation. When the button 451 labeled "Yes" is operated, the screen 450 is closed and the reproduction of the original voice is resumed.
Note that the count value of the counter 420 located on the left side of the screen 450 is incremented by one. For example, the notation of the numerator of the counter 420 in FIG. 21 was "0", but the notation of the numerator of the counter 420 in FIG. 22 is changed to "1".
In the case of processing operation example 1, even if the recording is successful, it is unknown how many of the replaceable regions have been successfully recorded. The number of areas can be confirmed with a specific numerical value. In other words, it is also possible to know the number of unrecorded areas. This makes it possible to increase the motivation.

<Display at the end of playback>
Finally, an example of display at the end of audiobook playback will be described.
FIG. 23 is a diagram for explaining an example of a screen that is automatically displayed when there is at least one area recorded by the user when the reproduction of the audiobook is finished. In FIG. 23, parts corresponding to those in FIG. 12 are shown with reference numerals.
The screen in FIG. 23 assumes that the created audiobook is automatically saved. For example, if the user is a child, it may be difficult to operate even if a screen prompting confirmation of whether or not to save the audiobook is displayed each time playback of the audiobook is completed.
Therefore, in FIG. 23, the terminal 30 automatically executes the saving itself, and notifies the fact of saving on the screen 460 .

In the case of FIG. 23, a screen 460 is displayed that informs the user that an original audiobook has been created and saved. The screen 460 displays messages such as "Congratulations!!", "You have used the book you made!" Note that when a button 461 having the notation "To Honda" is operated, the screen 460 is closed and switched to a screen for managing a storage area called a bookshelf in which audiobooks are stored.
In the case of this embodiment, creation of an original audiobook includes the case where part of an existing audiobook is modified.
In the case of FIG. 23, the numerator of counter 420 is "8". Thus, the user can also see that the audiobook created has audio recordings for 8 of the 10 regions that can be replaced.

FIG. 24 is a diagram illustrating an example of a screen used when the user designates an area for storing the created original audiobook. In FIG. 24, the parts corresponding to those in FIG. 23 are indicated by the reference numerals.
Note that the screen 470 shown in FIG. 24 may be displayed when the button 461 (see FIG. 23) having the notation "To Honda" is operated.
Although the automatic saving of created audiobooks is a convenient function, it may be difficult for users to find the audiobooks they want, such as when audiobooks of different users are mixed in one save destination.
Therefore, in FIG. 24, a screen 470 is prepared for the user to specify the save destination.

A screen 470 shown in FIG. 24 has a message "Please select Hondana" indicating an operation to be requested of the user, and the names "Hondana", "Taro", and "Hanako" which are candidates for the save destination. folder is placed. In addition, on the screen 470, a button 471 having the notation of "Change" and a button 472 having the notation of "Next" are also arranged.
In the case of this embodiment, the "Hondana" folder is for storing audiobooks purchased by the user, the "Taro" folder is for storing audiobooks replaced with Mr. Taro's voice, and the "Hanako ' folder is for storing audiobooks replaced with Hanako's voice.
In the case of FIG. 24, the "Taro" folder is selected as the save destination. When the button 471 is operated to change the storage destination, the selected folders are changed in order. Note that when the button 472 is operated, the created audiobook is saved in the selected folder.

FIG. 25 is a diagram showing a display example of a screen displayed after saving of the created audiobook is completed.
In FIG. 25, parts corresponding to those in FIG. 13 are shown with reference numerals.
Since the screen shown in FIG. 25 is at the time when the audiobook has finished playing, the slider 411 has reached the right end of the time axis 410 .
In addition, since there is an area in which voice is recorded, the display color of the area other than the positions indicated by the fifth and seventh speech balloons 412 from the top is changed to a color indicating the presence of recording, and at the same time the counter 420 is displayed. is changed to "8/10".
This display allows the user to visually confirm the result of recording in the audiobook created this time.
