Description

  The present invention relates to a technique for registering a bookmark in text data and voice data.

  A composite playback apparatus that plays back music file contents and image / text file contents in association with each other is known (for example, see Patent Document 1). For example, in this composite playback device, a conversation learning scene and text can be displayed on the display unit, and sound related to the display can be played from a sound generator, thereby realizing a language learning device for language learning. Can do. There is also known an electronic dictionary device that can read a text while displaying the text (see, for example, Patent Document 2). In addition to language learning, these conventional techniques are also used for electronic books that reproduce the contents of a novel while displaying novel text, for example.

  There are synchronous reproduction and asynchronous reproduction as text and audio reproduction modes by a text audio reproduction apparatus which is an apparatus to which the above-described conventional technology is applied. Synchronous playback is a mode in which the page of text display is switched in accordance with the playback of audio or scrolled in accordance with playback. For example, text-to-speech playback (also referred to as reading playback) corresponds to synchronous playback. On the other hand, asynchronous playback is a mode in which the page switching and scrolling of audio playback and text display are not synchronized. For example, this mode is useful when a viewer listens to reproduced audio and reads a text screen displaying content that does not match the content of the audio.

  When text and audio are viewed using the above text audio playback device, there are cases where it is desired to stop playback and resume later when the text and audio are viewed. Conventionally, with regard to the text display function, reproduction start position information corresponding to a bookmark of a book is registered in correspondence with the text data displayed on the screen, and the registered reproduction start position information is read out. Was able to know the text playback resume position.

Therefore, by reading and setting the bookmark information later, it is possible to easily resume the reproduction of text data and audio data from any position.

[Second Embodiment]
Since the external appearance and block configuration of the electronic dictionary to which the text sound reproducing apparatus according to the second embodiment of the present invention is applied are the same as those of the first embodiment described above, description of these configurations will be omitted.

  Next, the operation | movement of the text audio | voice reproduction | regeneration processing of the electronic dictionary in 2nd embodiment is demonstrated. FIG. 12 is a flowchart for explaining the text voice reproduction process of the electronic dictionary 1. When the control unit 21 of the electronic dictionary 1 reads out the electronic dictionary control program (including the text voice reproduction program) stored in the program storage unit 23a into the work area for development in the work area 24 and starts executing the program, FIG. The process of the flowchart shown is executed. When the menu 16 is pressed by the operator, the control unit 21 displays a function selection menu on the screen of the display unit 18. Next, when the item of the synchronized playback function is selected from the function selection menu by the operation of the cursor key 14 by the operator and the determination key 13 is pressed, the control unit 21 sets the synchronized playback function (S1201).

  When the synchronous playback function is set by the processing in step S1201, the control unit 21 displays a playback file selection menu on the screen of the display unit 18. The playback file selection menu is provided so that the control unit 21 reads a playback identifier corresponding to synchronous playback from the playback association information stored in the playback control information storage unit 23e, and can select a selection item corresponding to each playback identifier. It is a thing. In the example of FIG. 3, the control unit 21 reads ID0001 and ID0002 from the reproduction association information, and sets and displays the selection items corresponding to these reproduction identifiers in the reproduction file selection menu. Next, when a desired selection item is selected from the reproduction file selection menu by the operation of the cursor key 14 by the operator and the determination key 13 is pressed, the control unit 21 reads the text data associated with the selected reproduction identifier. The file name, the audio data file name, and the script data file name are read from the reproduction association information (S1202).

  Next, the control unit 21 reads the text data file corresponding to the text data file name from the text data storage unit 23c to the work area 24, and reads the voice data file corresponding to the voice data file name from the voice data storage unit 23d to the work area. 24, and the script data file corresponding to the script data file name is read from the reproduction control information storage unit 23e to the work area 24. Then, the control unit 21 starts displaying the text data from the head address on the display unit 18, and starts audio data decoding processing and audio output from the audio output unit 25. In addition, the control unit 21 compares the time stamp included in the audio data with the time stamp included in the script data, and when both type stamps match, the control unit 21 determines from the text address associated with the time stamp of the script data. Screen control for displaying text data (page switching display) on the display unit 18 is started (S1203).

  Next, the control unit 21 determines whether or not an operation on the display screen of the display unit 18 has been performed (S1204). Specifically, it is determined whether the page feed key 15 is operated or the cursor key 14 is operated. When the control unit 21 determines that the operation of the display screen has been performed in the process of step S1204 (S1204: YES), the control unit 21 cancels the synchronous playback function and switches the page or scrolls the display screen of the text data. The page is moved (S1205). On the other hand, when the control unit 21 determines that the operation of the display screen is not performed in the process of step S1204 (S1204: NO), the process proceeds to step S1206.

  Next, the control unit 21 determines whether or not the registration key 17 has been pressed (S1206). When the control unit 21 determines that the registration key 17 has been pressed in the process of step S1206 (S1206: YES), the control unit 21 cancels the synchronous playback function, and the first text data displayed on the display unit 18 is displayed. A cursor is displayed on a character (for example, the character on the upper left of the display screen). Then, by the operation of the cursor key 14 and the page feed key 15 by the operator, the cursor is moved to a position where the operator wants to set a bookmark. Then, the bookmark position is determined by pressing the determination key 13. Next, the control unit 21 reads the text address which is the address on the work area 24 corresponding to the first character of the text data displayed on the display unit 18 and the time stamp of the voice data when the registration key 17 is pressed. And bookmark information in which the bookmark address, which is the address on the work area 24 corresponding to the character on which the cursor is displayed, is associated with the bookmark number. The control unit 21 associates the bookmark information with the reproduction identifier and stores the bookmark information in the bookmark storage unit 23f, and the process proceeds to step S1208 (S1207). On the other hand, when the control unit 21 determines that the registration key 17 has not been pressed in the process of step S1206 (S1206: NO), the process proceeds to step S1208.

  Next, the control unit 21 determines whether or not a predetermined key (for example, “S” key) associated with execution of the reproduction stop process has been pressed (S1208). If the control unit 21 determines that a predetermined key has been pressed in the process of step S1208 (S1208: YES), the control unit 21 stops the execution of the text data and voice data playback process and ends the text voice playback process. (S1209). On the other hand, when the control unit 21 determines that the predetermined key is not pressed in the process of step S1208 (S1208: NO), the synchronous playback function is set and the process returns to step S1204.

  Next, a specific description will be given using text data used in the first embodiment.

The screen after scrolling the data is displayed. Further, the balloon diagram of FIG. 5B schematically shows the reproduction of the audio data corresponding to the passage of time. According to FIG. 5B, the sound reproduced in 9 seconds after the start of the synchronized reproduction corresponds to the text of the part underlined in the balloon diagram. Assume that the registration key 17 is pressed when 9 seconds have elapsed since the start of synchronous reproduction, which is the timing shown in FIG.

  FIG. 14 is a diagram showing how a bookmark position is determined by displaying a cursor. FIG. 14A is a diagram illustrating a state in which the registration key 17 is pressed by the operator, and the cursor is displayed on the upper left character on the display screen at that time. FIG. 5B is a diagram showing a state where the first page is displayed by the operation of the previous page key 15a and the cursor key 14 by the operator, and the cursor is moved to a desired position. In FIG. 5B, the text address of the work area 24 corresponding to the character “I” displayed by the cursor is 0x00A8 (hexadecimal number).

  FIG. 15 shows that the registration key 17 is pressed at the timing shown in FIG. 13 and the decision key 13 is pressed after the cursor position is moved as shown in FIG. It is an example of the bookmark information memorize | stored.

  Next, the operation | movement of the text audio | voice reproduction | resumption process of an electronic dictionary in 2nd embodiment is demonstrated with reference to the flowchart of FIG. 10 used for description in 1st embodiment. Since the processes in steps S1001 and S1002 are the same as the processes in the first embodiment, description of those steps is omitted.

  Following the processing of step S1002, the control unit 21 reads out the text data file corresponding to the text data file name from the text data storage unit 23c to the work area 24, and stores the audio data file corresponding to the audio data file name in the audio data storage. The script data file corresponding to the script data file name is read from the reproduction control information storage unit 23e to the work area 24. Then, the control unit 21 displays the text data on the display unit 18 from the text address, performs bookmark display on the character at the position indicated by the bookmark address, and performs decoding processing from the time stamp of the audio data and the audio output unit. Audio output from 25 is started. In addition, the control unit 21 compares the time stamp included in the audio data with the time stamp included in the script data, and when both type stamps match, the control unit 21 determines from the text address associated with the time stamp of the script data. The screen control for displaying the text data (page switching display) on the display unit 18 is started, and the text sound reproduction restart process is ended (S1003).

  Next, a specific example is shown. FIG. 16 is an example of a bookmark selection menu displayed on the display unit 18. The bookmark with the bookmark number 1 in the bookmark information shown in FIG. 15 corresponds to “A” in FIG. As in the first embodiment, the note symbols in the figure indicate that bookmarks are attached to the audio data.

  FIG. 17 is a diagram showing a state when the bookmark with the bookmark number 1 in the bookmark information shown in FIG. 15 is read and the text voice reproduction restart process is started. FIG. 5A shows a display screen at the start of the text audio reproduction restart process. As shown in FIG. 5A, a bookmark 1701 is displayed at the character corresponding to the bookmark address on the screen when resuming reproduction. The bookmark 1701 represents (highlights) the background color of the character corresponding to the bookmark position different from the background color of other characters. FIG. 5B shows a state in which sound is played back 9 seconds after the beginning of the sound data. In other words, in the same figure (b), it is shown that the voice data for 9 seconds from the beginning of the voice data corresponds to the text of the underlined part of the speech balloon diagram, and the underline is drawn when resuming playback. Playback of audio data is started from "I" who is not.

  Note that the bookmark 1701 may have a different character color from the character corresponding to the bookmark position, or may be decorated with a frame or a special character. You may make it distinguish from a character. In addition, text data from the upper left corner of the display screen to the character preceding the character corresponding to the bookmark position is highlighted, colored or decorated to distinguish it from other text data. Also good.

  As described above, the electronic dictionary in the present embodiment, when text data and audio data are reproduced synchronously or asynchronously, by pressing the registration key when desired, the time stamp of the audio data at that timing Is registered in the bookmark information. As for the display of the text data, the cursor displayed when the registration key is pressed is moved to the desired character position by operating the page feed key or the cursor key, and determined at that time. Register the display screen and bookmark position in the bookmark information. Thus, by reading the bookmark information later, it is possible to easily resume the reproduction of the audio data when the registration key is pressed and the display from the screen on which the bookmark is displayed.

  The embodiment of the present invention is not limited to an electronic dictionary, and can be applied to an electronic device or an information processing apparatus having an information processing function such as an electronic book, a mobile phone, or a personal computer.

  Moreover, you may make it implement | achieve the function of a part of information display apparatus which is embodiment mentioned above, for example, a control part with a computer. In this case, it is realized by recording a text voice reproduction program for realizing the control function on a computer-readable recording medium, and causing the computer system to read and execute the text voice reproduction program recorded on the recording medium. May be. Here, the “computer system” includes an OS (Operating System) and hardware of peripheral devices. The “computer-readable recording medium” refers to a portable recording medium such as a flexible disk, a magneto-optical disk, an optical disk, and a memory card, and a storage device such as a hard disk built in the computer system.
