Abstract

Methods, apparatus, and computer program products are described for enabling global grammars for a particular multimodal application according to the present invention by loading a multimodal web page; determining whether the loaded multimodal web page is one of a plurality of multimodal web pages of the particular multimodal application. If the loaded multimodal web page is one of the plurality of multimodal web pages of the particular multimodal application, enabling global grammars typically includes loading any currently unloaded global grammars of the particular multimodal application identified in the multimodal web page and maintaining any previously loaded global grammars. If the loaded multimodal web page is not one of the plurality of multimodal web pages of the particular multimodal application, enabling global grammars typically includes unloading any currently loaded global grammars.

Claims

1. A method for enabling global grammars for a particular multimodal application, the method implemented on a multimodal device supporting at least a voice mode of user interaction with the multimodal application, the method comprising:

loading a multimodal web page;

determining whether the loaded multimodal web page is one of a plurality of multimodal web pages of the particular multimodal application; and

managing enabling of one or more global grammars based at least in part on the determination of whether the loaded multimodal web page is one of the plurality of multimodal web pages of the particular multimodal application.

2. The method of claim 1, wherein the managing comprises:

if it is determined that the loaded multimodal web page is one of the plurality of multimodal web pages of the particular multimodal application, loading at least one global grammar in the loaded multimodal web page.

3. The method of claim 1, wherein the managing comprises:

if it is determined that the loaded multimodal web page is one of the plurality of multimodal web pages of the particular multimodal application, maintaining at least one previously loaded global grammar.

4. The method of claim 1, wherein the managing comprises:

if it is determined that the loaded multimodal web page is not one of the plurality of multimodal web pages of the particular multimodal application, unloading at least one global grammar.

5. The method of claim 1, wherein determining whether the loaded multimodal web page is one of the plurality of multimodal web pages of the particular multimodal application comprises comparing a base Universal Resource Identifier (URI) for the particular multimodal application with a designated URI in the loaded multimodal web page.

6. The method of claim 2, further comprising identifying the at least one global grammar based at least in part on markup in the loaded multimodal web page.

7. The method of claim 6, wherein identifying the at least one global grammar comprises identifying a scope attribute for a VoiceXML form in an X+V document.

8. Apparatus for enabling global grammars for a particular multimodal application, the apparatus supporting at least a voice mode of user interaction, the apparatus comprising at least one computer processor and a computer memory operatively coupled to the at least one computer processor, the computer memory having disposed within it computer program instructions that, when executed by the at least one computer processor, perform a method comprising:

loading a multimodal web page;

determining whether the loaded multimodal web page is one of a plurality of multimodal web pages of the particular multimodal application; and

managing enabling of one or more global grammars based at least in part on the determination of whether the loaded multimodal web page is one of the plurality of multimodal web pages of the particular multimodal application.

9. The apparatus of claim 8, wherein the managing comprises:

if it is determined that the loaded multimodal web page is one of the plurality of multimodal web pages of the particular multimodal application, loading at least one global grammar in the loaded multimodal web page.

10. The apparatus of claim 8, wherein the managing comprises:

if it is determined that the loaded multimodal web page is one of the plurality of multimodal web pages of the particular multimodal application, maintaining at least one previously loaded global grammar.

11. The apparatus of claim 8, wherein the managing comprises:

if it is determined that the loaded multimodal web page is not one of the plurality of multimodal web pages of the particular multimodal application, unloading at least one global grammar.

12. The apparatus of claim 8, wherein determining whether the loaded multimodal web page is one of the plurality of multimodal web pages of the particular multimodal application comprises comparing a base Universal Resource Identifier (URI) for the particular multimodal application with a designated URI in the loaded multimodal web page.

13. The apparatus of claim 9, wherein the method further comprises identifying the at least one global grammar based at least in part on markup in the loaded multimodal web page.

14. At least one recordable computer-readable medium encoded with computer-executable instructions that, when executed, perform a method for enabling global grammars for a particular multimodal application, the method implemented on a multimodal device supporting at least a voice mode of user interaction with the multimodal application, the method comprising:

loading a multimodal web page;

determining whether the loaded multimodal web page is one of a plurality of multimodal web pages of the particular multimodal application; and

managing enabling of one or more global grammars based at least in part on the determination of whether the loaded multimodal web page is one of the plurality of multimodal web pages of the particular multimodal application.

15. The at least one recordable computer-readable medium of claim 14, wherein the managing comprises:

if it is determined that the loaded multimodal web page is one of the plurality of multimodal web pages of the particular multimodal application, loading at least one global grammar in the loaded multimodal web page.

16. The at least one recordable computer-readable medium of claim 14, wherein the managing comprises:

if it is determined that the loaded multimodal web page is one of the plurality of multimodal web pages of the particular multimodal application, maintaining at least one previously loaded global grammar.

17. The at least one recordable computer-readable medium of claim 14, wherein the managing comprises:

if it is determined that the loaded multimodal web page is not one of the plurality of multimodal web pages of the particular multimodal application, unloading at least one global grammar.

18. The at least one recordable computer-readable medium of claim 14, wherein determining whether the loaded multimodal web page is one of the plurality of multimodal web pages of the particular multimodal application comprises comparing a base Universal Resource Identifier (URI) for the particular multimodal application with a designated URI in the loaded multimodal web page.

19. The at least one recordable computer-readable medium of claim 15, wherein the method further comprises identifying the at least one global grammar based at least in part on markup in the loaded multimodal web page.

20. The at least one recordable computer-readable medium of claim 19, wherein identifying the at least one global grammar comprises identifying a scope attribute for a VoiceXML form in an X+V document.
