Description

  The present invention can store the data position of an electronic book that has been browsed, for example, and is an information browsing apparatus suitable for a mobile phone or the like that does not have an input device that can directly designate a specific position on the screen. The present invention relates to an information browsing program, an information browsing program recording medium, and an information browsing system.

  In recent years, various information is provided in the form of electronic data. As an example of such electronic data, there is an electronic book obtained by digitizing a book supplied by paper. Normally, one e-book is not read at a stretch, and one e-book is read while being interrupted several times.

  As an invention for improving usability in such a situation, there are JP-A-2-89176 (hereinafter referred to as the first prior art) and JP-A-2001-184354 (hereinafter referred to as the second prior art).

  In the first related art, when the power of the electronic reading machine is turned off, the position of the page of the electronic book (or the position of the cursor) displayed immediately before is saved as bookmark data. And when reading the electronic book again, the bookmark data preserve | saved previously are selected and the electronic book is displayed from the position shown by the selected bookmark data.

In the second conventional technique, the start position and end position of the displayed electronic book can be specified, and the specified range can be stored as bookmark data. When the bookmark data is selected, the range indicated by the selected bookmark data is visually distinguished from other ranges. The second prior art also discloses an invention in which bookmark identification information such as a keyword or an icon is set in bookmark data.
Japanese Patent Laid-Open No. 2-89176 (published March 29, 1990) JP 2001-184354 A (published July 6, 2001)

  However, the first and second prior arts do not assume that “when reading an electronic book or the like, the last line of the displayed electronic data is divided and not completely read”. For example, consider a case where an electronic book is read on a mobile phone. In such a case, since a phone call has been received, the electronic book may be unavoidably closed even though only the middle part of the displayed electronic data has been read.

  In the first and second prior arts, when the book is suddenly closed as described above and the book is read again, it is difficult to understand “to which line (position) of the data displayed previously”. There was a problem of being bad. For example, as shown in FIG. 24, consider a case where the displayed electronic data 1001 is read up to a position 1002 and saved as a bookmark.

  In the first prior art, an electronic data position 1002 is designated using a cursor key, and the position is stored as bookmark data. Therefore, the user has to manually specify the electronic data position. For this reason, it was bad for the user. In particular, in a mobile phone that does not have an input device that can directly point to a specific position on the screen, such as a mouse, the electronic data position 1002 must be designated by pressing the cursor key many times.

  Further, in the second prior art, it is necessary to designate the start position and the end position of the displayed electronic book and to store these ranges as bookmark data. Therefore, even in the second prior art, in the situation where the user has to interrupt reading suddenly, the troublesome work of designating the range one by one was necessary.

  The present invention has been made to solve the above-described problems. For example, even in a situation where information browsing needs to be stopped suddenly, the user can easily save the position that the user is reading. It is an object of the present invention to provide an information browsing apparatus, an information browsing program, an information browsing program recording medium, and an information browsing system.

(Point of invention)
The main points of the invention for solving the above-mentioned problems can be summarized as follows.
・ For example, when an electronic book must be closed suddenly, the voice of a word or word string spoken by the user is recognized and matches the voice recognition result from the data range displayed on the electronic book data display device. Search for a string. Then, the data position of the character string that matches the voice recognition result is stored as bookmark data.

  As described above, by using voice input, the user does not have to manually specify the electronic data position.

  However, in the above-described solution configuration, when there are a plurality of character strings that match the speech recognition result, a situation that has not existed before occurs in which a plurality of data positions are stored as one bookmark data. A man-machine interface is required that allows the user to easily select a data position to be stored as bookmark data among a plurality of data positions. Further, when bookmark data including a plurality of data positions is stored and then the bookmark data is selected, the user can easily select a desired data position from among the plurality of data positions indicated by the bookmark data. -A machine interface is also required.

  The speech recognition dictionary creation unit 13 creates a word dictionary that defines words to be recognized by the speech recognition unit 14 and a language model that defines recognizable word strings, and stores them in the storage device 4. Hereinafter, a set of word dictionaries and language models is referred to as a speech recognition dictionary. The speech recognition dictionary may be created in advance from a large amount of text data such as a newspaper article. However, as will be described later, the speech recognition dictionary every time the electronic data display data creation unit 12 creates or updates display data. If you create, you can get the effect of improving speech recognition performance. In the present specification, the language model will be described as a network grammar format using words as nodes. However, the language model is not limited to the network grammar format, and may be a so-called Ngram language model indicating the frequency of word combinations. Further, when only the word is recognized, that is, when the word is not recognized continuously, the language model is not necessary.

  The voice recognition unit 14 recognizes the voice input from the voice input device 3 using the voice recognition dictionary and converts it into text. Note that the voice recognition unit 14 may be hardware configured by an LSI.

  In accordance with an instruction from the input device 2 or the voice recognition unit 14, the bookmark data storage unit 15 stores, for example, the data position of words in the electronic data area being displayed in the storage device 4 as bookmark data.

  The position specifying display data creating unit 17 creates display data that allows the user to easily understand the position indicated by the bookmark data, and displays the display data on the display device 6. The position specifying display data creation unit 17 will be described in detail later.

[Operation when saving bookmark data]
(Outline of processing when saving bookmark data)
Here, an outline of the operation when storing bookmark data will be described with reference to the flowchart of FIG.

  In S1, the electronic data selection unit 10 displays a list of electronic data in the storage device 4 (for example, a list of titles of electronic data, etc.) on the display device 6, and the one designated by the user is displayed in the work area. expand.

  In S2, the display data creation unit 12 for electronic data creates display data for the electronic data selected in S1.

In S3, the display data created in S2 is output to the display device 6.
In S4, the voice recognition dictionary creation unit 13 creates a voice recognition dictionary from the electronic data area being displayed. The speech recognition dictionary created in S4 is used in S8.

  Here, the speech recognition dictionary creation process will be described in detail with reference to FIGS. 4 (a) to 4 (c).

  First, for the electronic data area 200 being displayed (FIG. 4A), a sentence is divided into words by morphological analysis, and a word dictionary 201 (FIG. 4B) consisting of words indicated by bullets is created. . Then, the language model 202 (FIG. 4C) describing the word string in the electronic data area being displayed is created. In this case, a language model that can recognize not only sentences but also words is created.

  The language model 202 in FIG. 4C indicates that word strings corresponding to the respective node strings from the “start” node to the “end” node are recognizable. For example, the node sequence of “Start” → “Also” → “Right” → “M” → “Bright” → “Still” → “Look” → “Er” → “End” This means that the word string “visible” is recognizable. Words that are not in the word dictionary and word strings that are not defined in the language model are not recognized. Thus, since the speech recognition dictionary creation unit 13 creates a speech recognition dictionary from the data displayed on the display device 6, the number of words to be recognized can be reduced and an enormous amount of calculation is required. There is no need to install a large vocabulary speech recognition system.

  In addition, as shown in FIGS. 5 (a) to 5 (c), by using the ruby characters previously given to the kanji, only the kanji to which the ruby is given is registered in the word dictionary, and the rest is set as an unknown word. You may register. For example, in FIG. 5A, ruby characters are not assigned to the “right” 210a and “down” 210b kanji in the displayed data 210. Therefore, in the word dictionary 211 (FIG. 5B) and the language model 212 (FIG. 5C), these words are treated as unknown words. When ruby characters are used in this way, the amount of calculation can be reduced because there is no need for morphological analysis. However, all Kanji characters without a ruby character are treated as unknown words. In other words, all kanji characters that do not have reading kana are treated as the same word. The unknown word acoustic model may be, for example, a so-called garbage model in which features of all phonemes are learned.

  In S5, the scroll control unit 11 determines whether or not there is an instruction to scroll the electronic data from the user. If there is an instruction, the process proceeds to S11. If there is no instruction, the process proceeds to S6.

  In S11, the scroll control unit 11 calculates how much it should move from the position currently displayed on the electronic data display device 6. For example, a rule such as scrolling one line when the jog dial is clicked once may be determined in advance. Then, the electronic data display data creation unit 12 creates display data from the calculated position.

  In S6, it is determined whether or not there is an instruction to save bookmark data from the user. If there is an instruction from the bookmark data storage unit 15, the process proceeds to S7.

  In S <b> 7, it is determined whether or not voice is input from the voice input device 3. If it is a voice input, the process proceeds to S8. If not, the process proceeds to S9.

  In S8, the input voice is recognized, and bookmark data is saved based on the recognition result. Regarding the processing of S8, three examples (A, B and C) will be described below.

  In S9, the same manual bookmark storing process as that of the conventional technique using the input device 2 is performed. That is, the present invention can also have the functions of the prior art.

  In S <b> 10, the bookmark data storage unit 15 associates the stored bookmark data with the electronic data displayed on the display device 6. For example, the title of the electronic data may be assigned to the bookmark data to associate them, and the bookmark data may be stored as electronic data as independent data. Then, as shown in FIG. 6, only bookmark data corresponding to the electronic data “picnic diary” having the same content can be shared between the different information browsing apparatuses X and Y via the external storage medium 9.

(Processing when saving bookmarks-Example A)
Here, with reference to the flowchart of FIG. 7, a detailed description will be given of an embodiment of the bookmark data storage process in S8.

  In S <b> 101, the voice recognition unit 14 recognizes the voice input by the voice input device 3. At this time, the speech recognition dictionary created in S4 is used.

  In S102, the bookmark data storage unit 15 stores the electronic data position indicated by the character string of the voice recognition result as bookmark data. At this time, the character string itself of the voice recognition result may be stored as bookmark data (hereinafter, the electronic data position stored as bookmark data is simply referred to as the electronic data position indicated by the bookmark data).

  FIG. 8 assumes a situation in which, when electronic data is displayed as in 1001, the user speaks “weather” and is correctly recognized. In that case, electronic data positions corresponding to the character string “weather” (in FIG. 8, surrounded by broken lines and displayed in bold) are stored (seven locations).

  FIG. 9 assumes a situation in which the user utters the sentence “I have confirmed the weather forecast properly” and is correctly recognized. In that case, the electronic data position corresponding to the sentence (1003) is stored.

  However, the bookmark data is not limited to that described above, and may be composed of, for example, the start position of the displayed electronic data and the recognition result character string. That is, it is only necessary to know the electronic data position corresponding to the character string of the recognition result from the bookmark data.

(Processing when saving bookmarks-Example B)
Here, with reference to the flowchart of FIG. 10, a detailed description will be given of an embodiment of the bookmark data storage process of S8. The process described here is a process for uniquely determining an electronic data position to be stored as a bookmark when there are a plurality of character strings that match the voice recognition result in the electronic data area being displayed.

  In S <b> 101, the voice recognition unit 14 recognizes the voice input by the voice input device 3. At this time, the speech recognition dictionary created in S4 is used.

  In S103, it is determined whether or not there is only one character string that matches the recognition result in the electronic data area being displayed. If there is only one, the process proceeds to S102. If there are more than one, the process proceeds to S104.

  For example, as shown in FIG. 8, when electronic data is displayed as in 1001, a situation is assumed in which the user speaks “weather” and correctly recognizes it. In that case, since there are a plurality of character strings and weather (enclosed in broken lines and displayed in bold in FIG. 8 for easy understanding) in the electronic data area being displayed, the process proceeds to S104.

  In S104, the bookmark data storage unit 15 instructs the user so that the character string in the displayed electronic data area that matches the recognition result can be narrowed down to one.

  For example, assume that a user speaks “weather” and correctly recognizes it when electronic data is displayed as 1001 in FIG. In this case, since there are a plurality of “weathers”, the user is asked which character string position of “weather” in the electronic data area being displayed is to be stored as bookmark data, such as 1005.

  In S105, it is determined whether or not the voice recognition result in S101 is incorrect. For example, the user confirms whether or not the voice recognition result in S101 is correct. And when it is misrecognition, the process of the flowchart of FIG. 10 is complete | finished.

  In S106, the voice recognition dictionary creation unit 13 restricts the voice recognition dictionary. Specifically, a speech recognition dictionary is created from only sentences including the recognition result of the electronic data area being displayed. This is because it is not necessary to recognize all the words in the displayed electronic data area because only the electronic data position to be stored is input.

  In the situation shown in FIG. 11, the user selects the “weather” to be selected, so that the next input voice only needs to recognize a sentence including “weather”. Not answer). Therefore, a word dictionary and a language model are created from only words including sentences including “weather”.

  By limiting the speech recognition dictionary, the vocabulary to be recognized can be reduced. Accordingly, recognition performance can be improved and the amount of calculation required for recognition can be reduced.

  In S <b> 107, it is determined whether or not the user has selected a character string in the electronic data area being displayed using the input device 2.

  In S108, it is determined whether or not the user further inputs a voice. In the next speech recognition processing in S101, the speech recognition dictionary restricted in S106 is used.

If there is no input in S107 or S108, the process proceeds to S102. In this case, a plurality of electronic data positions are stored as bookmark data.
In S102, the bookmark data storage unit 15 stores the electronic data position indicated by the character string of the voice recognition result as bookmark data. At this time, the character string itself of the voice recognition result may be stored as bookmark data. However, the bookmark data is not limited to that described above, and may be composed of, for example, the start position of the displayed electronic data and the recognition result character string. That is, it is only necessary to know the electronic data position corresponding to the character string of the recognition result from the bookmark data.

  In this way, by determining the electronic data position to be stored as bookmark data as one, it becomes easy to understand to what position the previous display was read when the bookmark data is selected next time.

(Processing at the time of storing bookmarks-Example C)
Here, with reference to the flowchart of FIG. 12, one embodiment of the bookmark data storage process in S8 will be described in detail. The processing in FIG. 12 is basically the same as the flowchart in FIG. 10, but the speech recognition processing in S101 in FIG. 10 is different. Therefore, here, the processing of S101A to S101D of FIG. 12 which is different from FIG. 10 will be described below. Note that the processing of S101A to S101D is performed by the voice recognition unit 14.

  In S101A, voice recognition is performed in synchronization with the input voice, and an intermediate recognition result in units of syllables (or phonemes) is output.

  In S101B, it is determined whether or not there is a word including the halfway recognition result output in S101A in the electronic data area being displayed. If it is determined that there is a word including an intermediate recognition result, the process proceeds to S101C.

In S101C, the word including the halfway recognition result corresponding to S101B is highlighted.
In S101D, it is determined whether or not the user's voice input is completed. If it is still being input, the process returns to S101A.

  FIG. 13 shows an example of a moment when the user utters “Ten” in an attempt to speak “weather”. In S101A, the syllables “te” and “n” are recognized by voice, and in S101B, it is determined whether or not there is a word including the halfway recognition result “ten” in the displayed electronic data area 1011. The highlighted word is highlighted (enclosed in a square and the font is bold). The corresponding word may be highlighted from other character strings by changing the font size, changing the font color, changing the background color, or drawing an underline.

  As described above, when the speech recognition result is output halfway and there is a word including the syllable of the recognition result in the displayed electronic data area, the word including the syllable is highlighted and displayed. Candidates for electronic data positions to be stored as cage data are clearly known.

[Operation when bookmark data is selected]
Here, processing when bookmark data is selected will be described with reference to the flowchart of FIG. The process at the time of selecting bookmark data described here corresponds to the above-described embodiments A to C of the process at the time of storing bookmarks.

  In step S <b> 501, the bookmark data selection unit 16 causes the display device 6 to display a list of bookmark data corresponding to the electronic data displayed on the display device 6. The user selects bookmark data from the list.

  For example, as shown in FIG. 15, a list of bookmark data is displayed on the display device 6. However, FIG. 15 is a display example when the recognition result is given to the bookmark data, and the recognition result corresponding to each bookmark data is displayed.

  At this time, the method for selecting bookmark data may be either the input device 2 or the voice input device 3. However, if there is a large amount of bookmark data to be selected, voice input that does not require repeated key presses is more convenient.

  In S502, the position specifying display data creating unit 17 determines whether or not the electronic data position associated with the bookmark data selected by the user in S501 is single. If a single electronic data position is associated, the process proceeds to S503. Otherwise, the process proceeds to S504.

  In S503, the position specifying display data creating unit 17 displays electronic data from the vicinity of the electronic data position indicated by the bookmark data.

  In FIG. 16, electronic data is displayed from the electronic data position 1101 indicated by the bookmark data. FIG. 16 illustrates a case where the third “typhoon” from the top of the bookmark data list illustrated in FIG. 15 is selected in S501 of FIG. Although not shown, one sentence from the electronic data position indicated by the bookmark data may be emphasized by using bold, underline, font change or color reversal display. Note that it is not necessary to emphasize all the sentences, and only the data position may be emphasized.

  In S504, the position specifying display data creating unit 17 displays a plurality of electronic data positions indicated by the bookmark data. Two specific examples of S504 are shown below.

  FIG. 17 shows an example of the processing in S504 when the word or word string spoken by the user is recognized as “weather” and the data position is saved when the bookmark data is saved. In FIG. 17, a plurality of electronic data positions indicated by the bookmark data are displayed, and the user selects a desired electronic data position.

  FIG. 18 shows another example in the processing of S504 when the word or word string spoken by the user is recognized as “weather” and the data position is saved when the bookmark data is saved. In FIG. 18, a sentence including the electronic data position indicated by the bookmark data is shaped into a fixed length (in this example, a length that can be displayed in one line) and displayed in a list. As described above, since the sentences including the respective electronic data positions are extracted and displayed in a list, the user can easily select the electronic data positions stored when the bookmark data is stored. On the screen with a small amount of characters that can be displayed, such as a mobile phone, the display as shown in FIG. 18 is easy to use because the entire text is easy to grasp.

  As shown in FIG. 19, each of the bookmark data may be displayed slightly before the electronic data position. In this way, when displayed for a while, it is easy to grasp the meaning of the sentence at the saved position. Furthermore, when the speech recognition result is saved as bookmark data, the character string corresponding to the recognition result is emphasized over other character strings by using bold, underline, font change or color reversal display. May be displayed. By highlighting the keyword word, the position read last time is easy to understand.

  When one element of the list is selected, electronic data is displayed from the data position of the selected sentence.

  The bookmark data saving instruction unit 15A instructs to save the bookmark data of the electronic data currently displayed in the storage device 104 of the server device 100 in response to an input from the user input device 2 or the voice input device 3. do. At this time, the bookmark data is associated with the user ID, and the data is stored in the storage device 104. In addition, the user authentication unit 111 of the server apparatus 100 restricts only a person having a user ID associated with the stored bookmark data so as to have access authority to the bookmark data. The bookmark data saving process is the same as the above-described embodiment except that the storage location is the storage device 104 of the server apparatus 100.

  The bookmark data selection unit 16 </ b> A is associated with the electronic data displayed on the display device 6 and when there is bookmark data associated with the currently logged-in user ID (the storage device 104 of the server device 100). The list of the bookmark data is displayed on the display device 6 and the contents of the bookmark data selected by the user using the input device 2 or the voice input device 3 are displayed on the work of the storage device 4. Expand to the area. If there is no corresponding bookmark data, the user is notified that there is no bookmark data.

  Functional units other than those described above of the terminal device T1 perform substantially the same functions as the functional units of FIG.

  Next, the server apparatus 100 will be described. The hardware of the server device includes a storage device 104 (storage means, user management data storage means, terminal device instruction data storage means), a communication device 107, and a control device 101.

  The control device 101 includes a preprocessor and a memory, and operates according to a control program stored in the storage device 104, for example. More specifically, a user authentication unit 111 (user authentication unit) and an electronic data transmission unit 110 (electronic data transmission unit), which will be described later, are configured, and processing results thereof are stored in the storage device 104. The stored data is output to the communication device 107.

  The storage device 104 includes a RAM or a ROM, and stores electronic data including bookmarks associated with the work area, text, image data, audio data, and the like for storing temporary data and processing data. ing. The storage device 104 stores user management data describing a user ID and a password corresponding to the user ID.

  The communication device 107 is configured by a network interface card or the like, and transmits / receives data to / from the terminal device T1 connected via a network cable or the like.

  The user authentication unit 111 is configured by the control device 101 and a program executed by the control device 101, and determines whether or not the user ID and password transmitted from the terminal device T1 are registered in the user management data of the storage device 104. . If it is determined that the transmitted user ID and password are registered in the user management data, the user (the user who uses the terminal device that transmitted the user ID) is notified to the electronic device of the storage device 104. Access authority to the data and bookmark data of the user (bookmark data associated with the transmitted user ID) is given. On the other hand, if the user ID and password are not registered, the user is informed that “not registered”.

  The electronic data transmission unit 110 transmits the electronic data or bookmark data only to the user authenticated by the user authentication unit 111 in accordance with the electronic data browsing operation instruction of the terminal device T1. Note that nothing is transmitted to a user who is not authenticated by the user authentication unit 111.

  Further, instead of storing bookmark data in the storage device 104 of the server device 100, bookmark data may be stored in the storage device 4 of the terminal device T1 as long as bookmark data and electronic data are associated with each other.

  In the above description, the terminal device T1 and the server device 100 have a one-to-one correspondence. However, as a matter of course, a configuration in which the server device 100 corresponds to a plurality of terminal devices T1 to Tn as shown in FIG. It is.

  According to the embodiment of the server / client system described above, electronic data and bookmark data can be centrally managed on the server side. That is, unauthorized duplication of electronic data can be restricted. It is also possible to realize a rental service such as issuing a user ID and password valid for a certain period to a user who has paid a predetermined fee.

[Embodiment 2 in Server / Client System]
Here, with reference to FIG. 22, another embodiment of a server / client system including a plurality of terminal devices and server devices as clients in the information browsing system of the present invention will be described.

  In the above embodiment, every time the electronic data area being displayed on the information browsing device (terminal device) is updated, the speech recognition dictionary creating unit 13 of the information browsing device creates a speech recognition dictionary. This places a burden on the control device of the information browsing device.

  In general, in a server / client system, a server device is configured using a high-performance device. Therefore, considering the entire system, it is better to provide the server device 100 with the speech recognition dictionary creation unit 113. Hereinafter, an example in this case (only functional units different from those in FIG. 20) will be described.

  22 includes an input device 2 as a manual input unit, a voice input device 3 (speech input unit) as a voice input unit, a display device 6 (display unit) as a display unit, and a communication as a data transmission / reception unit. Device 7, electronic data selection unit 10B (electronic data receiving unit), scroll control unit 11, electronic data display data creation unit 12, voice recognition dictionary restriction unit 13B (voice recognition unit), voice recognition unit 14 (voice recognition unit) ), A bookmark data storage instruction unit 15A (bookmark data storage instruction unit), a bookmark data selection unit 16A, a position specifying display data creation unit 17 and a login unit 18 (login unit).

  22 constitutes a user authentication unit 111 (user authentication unit), an electronic data transmission unit 110B (electronic data transmission unit), and a voice recognition dictionary creation unit 113 (voice recognition unit), and processing results thereof. Is stored in the storage device 104, and data stored in the storage device 104 is output to the communication device 107.

  The voice recognition dictionary creation unit 113 creates a voice recognition dictionary corresponding to the electronic data stored in the storage device 104. In this case, since the speech recognition dictionary only needs to be created once, it is not necessary to create the speech recognition dictionary each time the display of electronic data is switched.

  In addition, if the speech recognition dictionary is divided into fine units such as electronic data pages, chapters, or XML specific tags, the processing of the speech recognition dictionary restriction unit 13B described later can be reduced. In FIG. 23, in the electronic data 2000, voice recognition dictionaries 2001-200n are created for each page.

  The electronic data transmission unit 110B provides electronic data and a voice recognition dictionary or bookmark data corresponding to the electronic data to only the user authenticated by the user authentication unit 111 in accordance with the electronic data browsing operation instruction of the terminal device T1. Is transmitted to the terminal device T1. Note that nothing is transmitted to a user who is not authenticated by the user authentication unit 111.

  The electronic data selection unit 10B receives a list of electronic data (stored in the storage device 104 of the server device 100) (for example, the title of the electronic data) via the communication line 99 and sends them to the display device 6. At the same time, the electronic data selected using the input device 2 or the voice input device 3 is developed in the work area of the storage device 4 of the terminal device T1. At that time, the voice recognition dictionary corresponding to the electronic data is received and stored in the storage device 4.

  The speech recognition dictionary restriction unit 13B appropriately restricts the vocabulary of the received speech recognition dictionary according to the electronic data area being displayed. Specifically, the words and word strings in the speech recognition dictionary received from the server device 100 are further limited to those in the electronic data area being displayed. If the speech recognition dictionary is divided (for each page as shown in FIG. 23), it is only necessary to switch the speech recognition dictionary each time the page is switched.

  As described above, by creating a speech recognition dictionary corresponding to each electronic data in the server device 100 in advance and transmitting it to the terminal device T1, the processing of the terminal device T1 can be reduced. The speech recognition dictionary restriction unit 13B only restricts the words of the speech recognition dictionary received from the server device (or extracts a part of the speech recognition dictionary), and performs calculation more than the process of creating the speech recognition dictionary. The amount is much smaller.

  When the speech recognition dictionary is divided into fine units such as electronic data pages, chapters, or XML specific tags, the speech recognition dictionary restriction unit 13B switches the speech recognition dictionary according to the display. Since it is sufficient, processing can be further reduced.

  As described above, in the information browsing apparatus of the present invention, the input voice is recognized, and the data position of the character string that matches the recognition result is stored as bookmark data, so the user manually specifies the electronic data position. There is no need to do.

  Also, when storing bookmarks, recognition performance can be improved by defining words and word strings that are subject to speech recognition from the currently displayed electronic data, and the amount of extra computation can be reduced.

  In addition, reading kana given to kanji in advance is registered as a word for speech recognition, and words without reading kana are registered as unknown words, so morphological analysis that requires great machine power is not used May be.

  In addition, by confirming the electronic data position to be stored as bookmark data to one, it becomes easy to understand to what position the previous display was read when the bookmark data is selected next time.

  The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope shown in the claims, and embodiments obtained by appropriately combining technical means disclosed in different embodiments. Is also included in the technical scope of the present invention.

  The present invention can be applied to an apparatus and a system for browsing information including text, such as browsing an HTML file, in addition to browsing an electronic book as described in the above embodiment.
