Abstract

To convert the structure of a Web page into contents that a user can easily listen to, and for permitting the user to access and obtain information without have to perform and navigation, in a manner similar to listening to the radio. A designated target page is obtained from a Web server, and a linked list for the target page is analyzed to obtain a linked destination page. A transcoding module inserts the main content of the linked destination page into a linked location on the target page, and converts the page into a structure appropriate for oral reading. Then, a VoiceXML generation module converts the target page into a VoiceXML document, and a VoiceXML browser performs a speech response process for the VoiceXML document. A command is input to the VoiceXML browser orally or by using a dial key entry provided using a telephone, and a speech from the VoiceXML browser is output to the telephone.

Claims

1. An information access method, said method comprising the steps of:

designating a link or a linked list in a web page;

obtaining a linked destination page designated in said link or in said linked list;

inserting all or a part of the content of said linked destination page into a linked location at said web page; and

outputting speech for all or a part of said content of said linked destination page inserted into said linked location at said web page.

2. The information access method according to claim 1, wherein one part of said linked destination page that is inserted into said linked location at said web page is the main content of said linked destination page.

3. The information access method according to claim 2, wherein said main content of said linked destination page is extracted using a first method for referring to annotation information or using a second method for extracting a difference from a page that is similar to said linked destination page.

4. The information access method according to claim 1, wherein a process for the insertion of said linked destination page is recorded as said annotation information, and by referring to said annotation information the following process is automatically performed.

5. The information access method according to claim 1, said method further comprising a step of:

converting, into a VoiceXML document, said web page into which part or all of said linked destination page has been inserted.

6. The information access method according to claim 5, wherein, for the conversion into the VoiceXML document, each element of a web page is allocated to the VoiceXML form, and is read orally in consonance with prompts included in the form.

7. The information access method according to claim 6, wherein the time-out for the form is set to 0, and wherein the elements are orally read sequentially while the processing for said form is performed in order.

8. The information access method according to claim 6, wherein, when the same grammars for a key input operation and a speech operation are set for said form, and an interrupt is permitted, a command is accepted during the processing performed for said form.

9. The information access method according to claim 7, wherein the destination for the output of a speech is a telephone, and through said telephone, a command is input using speech or a dial tone.

10. The information access method according to claim 1, wherein, for speech output, sound effects are added that reflect the structure, the volume, and the current processing location of the Web page content, and other associated information.

11. The information access method according to claim 1, wherein, along with the speech the screen of said web page is displayed on a display device.

12. The information access method according to claim 1, said method further comprising the steps of:

detecting the main frame for said web page;

generating a link correlated with a frame other than said main frame; and

adding said link to said main frame.

13. The information access method according to claim 12, wherein said main frame is detected as a first element, a frame that is to be displayed in the largest area, a second element, a frame in which the greatest number of characters are included, or a third element, a frame having the greatest index that is used to weight said first and said second elements, or a combination of the elements.

14. The information access method according to claim 13, said method further comprising the step of:

rearranging groups in said main frame in accordance with annotation when said annotation is added to said main frame, and inserting text or a link into said main frame or performing another operation.

16. The information access system according to claim 15, wherein one part of said linked destination page that is inserted into said linked location at said web page is the main content of said linked destination page.

17. The information access system according to claim 15, said method further comprising:

a recorder for recording, as said annotation information, a process for the insertion of said linked destination page; and

a performer for automatically performing the following process by referring to said annotation information.

18. The information access system according to claim 15, further comprising:

a converter for converting, into a VoiceXML document, said web page into which part or all of said linked destination page has been inserted.

19. The information access system according to claim 15, wherein the destination for the output of a speech is a telephone, and through said telephone, further comprising:

an acceptor for accepting input using speech or a dial tone.

20. The information access system according to claim 15, wherein said speech output means includes means for adding sound effects that reflect the structure, the volume, and the current processing location of the Web page content, and other associated information.

21. The information access system according to claim 15, further comprising:

a displayer for, along with the speech, displaying the screen of said web page is displayed on a display device.

22. The information access system according to claim 15, further comprising:

a detector for detecting the main frame for said web page;

a generator for generating a link correlated with a frame other than said main frame; and

an adder for adding said link to said main frame.

23. The information access system according to claim 22, wherein said main frame is detected as a first element, a frame that is to be displayed in the largest area, a second element, a frame in which the greatest number of characters are included, or a third element, a frame having the greatest index that is used to weight said first and said second elements, or a combination of the elements.

24. The information access system according to claim 23, further comprising:

a rearranger for rearranging groups in said main frame in accordance with annotation when said annotation is added to said main frame, and inserting text or a link into said main frame or performing another operation.

15. An information access system comprising:

a designator for designating a link or a linked list in a web page;

an obtainer for obtaining a linked destination page designated in said link or in said linked list;

an inserter for inserting all or a part of the content of said linked destination page into a linked location at said web page; and

an outputter for outputting speech for all or a part of said content of said linked destination page inserted into said linked location at said web page.

25. A program storage device readable by machine, tangibly embodying a program of instructions executable by the machine to perform method steps for facilitating data clustering, said method comprising the steps of:

designating a link or a linked list in a web page;

obtaining a linked destination page designated in said link or in said linked list;

inserting all or a part of the content of said linked destination page into a linked location at said web page; and

outputting speech for all or a part of said content of said linked destination page inserted into said linked location at said web page.
