Description

  The present invention relates to a content calling apparatus and a content calling method for calling content data described in a predetermined markup language from a server by voice input.

  In general, electronic devices such as a mobile phone, a portable information terminal, and an in-vehicle navigation device are connected to a server via a network to acquire desired content data. Such access to content has been performed by a browser using a GUI (Graphical User Interface) displayed on a display provided in an electronic device. In addition, as a method for calling a desired content, a method of following a hierarchical menu is often employed.

  For example, in an in-vehicle navigation device, in order for a user to call a desired content (for example, news in general) using the GUI while the map screen shown in FIG. The top menu screen shown in b) is displayed. Then, an item (for example, news) corresponding to the desired content is selected from the items displayed on the top menu. Then, an item menu screen (FIG. 9C) showing the content of the selected item is displayed, and an item (for example, general) corresponding to the desired content is selected from here. When an item corresponding to the desired content is selected, an item menu screen indicating the content is displayed (for example, a general news article list shown in FIG. 9D). In addition, when each article (Article 1, Article 2, Article 3, etc.) is selected in the news general article list shown in FIG. 9D, the details of each article are displayed.

  However, in order to reach the screen showing the content of the desired content from the screen normally displayed on the electronic device, it is necessary to go through the top menu and the item menu, so that the GUI operation by the user becomes complicated. There's a problem.

A technique for moving to the next content or inputting data to a form by voice input is known (for example, Patent Document 1). According to this technology, speech of a user's speech is recognized and movement to the next content or data input to a form is performed using the recognition result.

  However, even in the technique of Patent Document 1, in order to reach the screen showing the content of the desired content, it is necessary to go through the top menu and the item menu. There is a problem that it becomes complicated.

  The present invention has been made to solve such a problem, and eliminates the troublesome operation of sequentially traversing the menu of the hierarchical structure, so that desired contents can be easily called. For the purpose.

  In order to solve the above-described problems, in the present invention, a recognition target word / phrase for specifying content and content location information are stored in association with each other. Then, the speech input speech is recognized, and the speech recognition recognition phrase is compared with the recognition target phrase specifying the content. When the two match, the presence position information corresponding to the recognition target phrase is indicated. The site is accessed and the desired content is called.

  According to the present invention configured as described above, when a user calls a desired content, the desired content can be directly called by one voice input without going through a menu screen on the way. No complicated operation is required. Further, it is not necessary to repeatedly input voice when calling desired content. Therefore, the user can easily call desired content.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram illustrating a configuration example of a content transmission / reception system including a content calling device according to the present embodiment. As shown in FIG. 1, the content calling device 1 according to the present embodiment includes a voice input I / F 2, a voice recognition unit 3, a display controller 4, a data storage unit 5, a communication unit 6, and a control unit 7. Yes.

  The content transmission / reception system including the content calling device 1 according to the present embodiment is connected to the content calling device 1, the audio input I / F 2 of the content calling device 1, the microphone 20 for inputting sound, and the content calling device 1. A display 40 connected to the display controller 4 is configured by a display 40 for displaying images, a network network such as the Internet 9, and a server 10. In the server 10, content data is stored in the content data storage unit 11 in correspondence with presence position information, for example, a URL (Uniform Resource Locator).

  The voice input I / F 2 inputs the voice input by the microphone 20 into the content calling device 1. The voice recognition unit 3 recognizes voice input from the voice input I / F 2. Here, the speech recognition unit 3 includes a dictionary DB that stores a recognition target phrase that is a recognition target and a recognition ID in association with each other, and the recognized phrase recognized by the speech recognition unit 3 is identified by the recognition ID. Is done.

  The display controller 4 displays a menu screen or a screen based on the called content on the display 40. When the content calling device 1 according to the present embodiment is mounted on an in-vehicle navigation device, a screen such as a map is displayed on the display 40. To display.

  The data storage unit 5 stores a recognition word / phrase table as shown in FIG. This recognition word / phrase table stores a recognition target word / phrase that is a voice to be recognized by the voice recognition unit 3, a recognition ID, and a URL of content specified by the recognition target word / phrase in association with each other. Here, when the page information of the top menu is acquired by the communication unit 6, the recognition word / phrase table is generated by the control unit 7 based on the description in the page information of the top menu and stored in the data storage unit 5. Here, the timing for acquiring the page information of the top menu may be periodically performed in the background, or may be performed when the top menu is displayed by a menu operation using a GUI.

  The communication unit 6 has a communication function, and is connected to a network such as the Internet 9 to access a designated URL and transmit / receive data.

  When the communication unit 6 acquires the top menu page information, the control unit 7 generates a recognition word / phrase table based on the description in the page information of the top menu and stores it in the data storage unit 5. In addition, the control unit 7 compares the recognition ID of the recognized word / phrase recognized by the voice recognition unit 3 with the recognition ID of the recognized word / phrase table stored in the data storage unit 5 and finds a matching recognition ID. If it exists, the URL corresponding to the recognition ID is read from the data storage unit 5, and this URL is output to the communication unit 6. The communication unit 6 accesses the server 10 via the Internet 9 based on the URL input from the control unit 7, and acquires content data corresponding to the URL described above from the content data storage unit 11 provided in the server 10. To the control unit 7. The control unit 7 outputs the content data input from the communication unit 6 to the display controller 4 and displays a screen based on the content on the display 40.

  In the present embodiment, for example, a screen as shown in FIG. That is, when the content call device 1 is mounted on an in-vehicle navigation device, the map image output from the navigation device is displayed on the display 40 in the initial state as shown in FIG. Yes. In this state, in order to display the content of the article list of the news in general, when “Zenpan” is input to the microphone 20 as shown in FIG. 3B, the screen of the corresponding content is immediately displayed on the display 40. Is displayed. The operation in this case is as follows.

  First, the voice recognition unit 3 recognizes the voice “Zenpan” inputted from the microphone 20 via the voice input I / F 2 and identifies the recognition ID of the inputted recognition phrase “Zempan” (this) In this case, the recognition ID is “1”). The control unit 7 compares the recognition ID of the recognized word / phrase recognized by the voice recognition unit 3 with the recognition ID of the recognized word / phrase table stored in the data storage unit 5. When the recognition ID of the recognized word / phrase recognized and the recognition ID of the recognized word / phrase table match, the control unit 7 reads out the URL corresponding to the matching recognition ID from the data storage unit 5, and the communication unit 6. Output to.

  Here, as shown in FIG. 2, when referring to the recognized word / phrase table stored in the data storage unit 5 for the recognized word / phrase “Zempan”, the recognition target word / phrase “Zempan” has “1” as the recognition ID. "Is attached, and it can be seen that the URL of the content corresponding to this is http: //.../all-list.xml. It should be noted that, as recognition target phrases corresponding to the same URL, “Saishin News” with a recognition ID “2”, “Saishin News” with a recognition ID “3”, and “Saishin News” with a recognition ID “4”. The same URL can be identified even if these recognition target words are uttered.

  In the communication unit 6, a URL (http: //... /All-list.xml) corresponding to the recognition target word “Zempan” is input from the control unit 7 and the server 10 is accessed based on this URL. The server 10 reads content data (news article list) corresponding to the URL from the content data storage unit 11. The communication unit 6 acquires content data from the server 10 and outputs the content data to the control unit 7. The control unit 7 outputs the acquired content data to the display controller 4 and displays a content screen as shown in FIG.

  Next, the operation of the content calling device and the content calling method according to the present embodiment will be described. FIG. 4 is a flowchart showing the operation of the content call device and the content call method according to the present embodiment. First, the control unit 7 checks whether or not a voice is input from the voice input I / F 2 (step S1). If no sound is input (NO in step S1), the process in step S1 is repeated.

  On the other hand, when a voice is input (YES in step S1), the voice recognition unit 3 recognizes the voice input from the voice input I / F 2 to check whether the voice recognition is successful. (Step S2). If the voice recognition is not successful (NO in step S2), an error is displayed on the display 40, or an error is output by a voice output unit (not shown) (step S3). Then, it is checked whether or not the voice input is performed again (step S4).

  If the voice input is not performed again (NO in step S4), the process ends. If the voice input is performed again (YES in step S4), the process returns to step S1. Whether or not to perform voice input again is determined based on whether or not an instruction to perform voice input again in response to an error output is given by the user.

  On the other hand, when the voice recognition is successful (YES in step S2), the control unit 7 recognizes the recognition ID of the recognized word / phrase recognized by the voice recognition unit 3 and the recognized word / phrase table stored in the data storage unit 5. Are compared with the recognition IDs of the URLs, and it is checked whether or not there is a URL corresponding to the recognition target word / phrase that matches the recognition word / phrase recognized by voice recognition (step S5).

  If there is no URL corresponding to the recognition target phrase that matches the recognized speech phrase (NO in step S5), in other words, the recognition ID of the recognized speech phrase and the recognition phrase table recognition. If the ID does not match, an error is displayed on the display 40, or an error is output by a voice output unit (not shown) (step S3). Then, it is checked whether or not the voice input is performed again (step S4).

  If the voice input is not performed again (NO in step S4), the process is terminated. If the voice input is performed again (YES in step S4), the process returns to step S1.

  On the other hand, if there is a URL corresponding to the recognition target phrase that matches the recognized speech phrase (YES in step S5), in other words, the recognition ID of the recognized speech phrase and the recognition phrase table recognition. If the ID matches, the control unit 7 activates a browser for displaying a screen based on the desired content (step S6). When the browser is activated, the control unit 7 reads the URL corresponding to the matched recognition ID from the data storage unit 5 and outputs it to the communication unit 6. The communication unit 6 accesses the server 10 based on the input URL (step S7).

  The server 10 reads content data corresponding to this URL from the content data storage unit 11. The communication unit 6 acquires content data from the server 10 and outputs the content data to the control unit 7. And the control part 7 displays the screen based on a desired content on the display 40 by outputting the content data input from the communication part 6 to the display controller 4 (step S8).

  Next, the recognition target phrase registration operation in the content calling device according to the present embodiment will be described. FIG. 5 is a flowchart showing the recognition target word registration operation in the content calling device according to the present embodiment. First, the control unit 7 checks whether or not the page information of the top menu has been acquired by the communication unit 6 (step S11). If the page information of the top menu is not acquired (NO in step S11), the process of step S11 is repeated.

  On the other hand, when the page information of the top menu is acquired (YES in step S11), the control unit 7 determines whether the URL of the content and the corresponding recognition target word / phrase are described in the description text of the top menu. (Step S12). For example, as shown in FIG. 6, the top menu is described in XML (extensible Markup Language), and “all-list.xml” described in the <link filetype = “XML_SUBJECT”> tag is related to the article list of general news. This indicates the URL of the content, and “Zenpan”, “Saishinno News”, “Saishin News”, and “Saishinno” described by the <voicekey> tag indicate the words to be recognized.

  If the URL of the content and the corresponding recognition target word / phrase do not exist in the acquired top menu page information (NO in step S12), the process ends.

  On the other hand, if the URL of the content and the corresponding recognition target word / phrase exist in the acquired top menu page information (YES in step S12), the control unit 7 determines the URL and the recognition target word / phrase. Based on the above, a recognition word / phrase table is generated and stored in the data storage unit 5 (step S13). Here, the control unit 7 stores the recognition ID corresponding to each recognition target word / phrase in the recognition word / phrase table, and also recognizes each recognition target word / phrase and the recognition ID corresponding to each recognition target word / phrase. Is stored in the dictionary DB. Accordingly, the user can call the desired content by inputting the recognition target word / phrase corresponding to the URL of the desired content from the voice input I / F 2.

  As described above in detail, according to the present embodiment, the URL of the content and the recognition target phrase are stored in association with each other, and when the user calls the desired content, the input voice is recognized and recognized. Since the content of the URL corresponding to the recognition target word / phrase that matches the word / phrase is called, the desired content can be directly called by one voice input without going through the menu screen. Therefore, the user can easily call up the desired content without performing complicated operations using a GUI or the like and performing voice input many times.

  In addition, according to the present embodiment, by acquiring the page information, it is possible to acquire the URL of the content and the recognition target word / phrase corresponding to the URL, so that the URL of the desired content can be easily updated. The contents of the data storage unit 5 can always be kept up-to-date. Since the top menu is frequently accessed, the frequency of updating can be increased by acquiring page information from the top menu. Further, according to the present embodiment, since XML is used as a language for describing the top menu, the degree of freedom of description is high, and the recognition target words and the like can be easily defined.

  In the present embodiment, when a top menu is acquired to call a desired content, a recognition word / phrase table in which the URL of the desired content is associated with a recognition target word / phrase is generated by XML describing the top menu, and the data Although it memorize | stores in the memory | storage part 5, it is not limited to this. For example, not only XML but also a language such as HTML (HyperText Markup Language) may be used. In addition, the recognition phrase table may be stored in advance in the data storage unit 5 of the content calling device 1, or the recognition phrase table is downloaded by the communication unit 6 at a predetermined timing and stored in the data storage unit 5. You may make it do.

  In the present embodiment, the recognition ID of the recognized word / phrase recognized by the voice recognition unit 3 is compared with the recognition ID of the recognized word / phrase table stored in the data storage unit 5, but the present invention is not limited to this. . For example, the recognition words / phrases recognized by the voice recognition unit 3 and the recognition target words / phrases in the recognition table stored in the data storage unit 5 may be directly compared.

  Moreover, in this embodiment, although the server 10 is accessed using the communication part 6 incorporated in the content calling device 1, it is not limited to this. For example, as shown in FIG. 7, a communication device 60 such as a mobile phone that can access the server 10 may be connected to a communication I / F 12 provided in the content calling device 1.

  Further, in the present embodiment, the user does not notify the recognition target word / phrase corresponding to the displayed content screen, but manually reaches the desired content using a GUI or the like, When a screen based on the content is displayed on the display 40, a recognition target word / phrase corresponding to the screen may be displayed on the display 40. For example, as shown in FIG. 8, when an article list of news in general is displayed on the display 40, “The recognition target word on this screen is“ Zempan ”” is displayed on the display 40. Thereby, the user can grasp what recognition target phrase the desired content corresponds to, and can easily perform voice input.

  In addition, by pressing a help key (not shown) or requesting a help screen display by GUI or voice input, a character string (for example, content name or content URL) indicating the content content and its A list of recognition phrases corresponding to the URL may be displayed. Thereby, the user can grasp what recognition phrase the desired content corresponds to, and can easily perform voice input.

  In addition, the said embodiment is only what showed the example in implementation in implementing this invention, and, as a result, the technical scope of this invention should not be interpreted limitedly. In other words, the present invention can be implemented in various forms without departing from the spirit or main features thereof.
