Enabling global grammars for a particular multimodal application
View Patent ↗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.
1. A method for enabling global grammars for a particular multimodal application, the method implemented with a multimodal browser and a multimodal application operating on a multimodal device supporting multiple modes of user interaction with the multimodal application, the modes of user interaction including a voice mode and one or more non-voice modes, 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;
if the loaded multimodal web page is one of the plurality of multimodal web pages of the particular multimodal application, loading any currently unloaded global grammars in the loaded multimodal web page and maintaining any previously loaded global grammars; and
if the loaded multimodal web page is not one of the plurality of multimodal web pages of the particular multimodal application, unloading any currently loaded global grammars.
2. The method of claim 1 , wherein determining whether the loaded multimodal web page is one of a plurality of multimodal web pages of the particular multimodal application further comprises comparing a base URI for the particular multimodal application with a designated URI in the loaded multimodal web page.
3. The method of claim 1 , wherein loading any currently unloaded global grammars in the loaded multimodal web page further comprises:
identifying in dependence upon markup in the loaded multimodal web page a global grammar;
determining that the identified global grammar is not currently loaded; and
loading the identified global grammar.
4. The method of claim 3 , wherein identifying in dependence upon markup in the loaded multimodal web page a global grammar further comprises identifying a scope attribute for a VoiceXML form in an X+V document.
5. The method of claim 1 , further comprising identifying in dependence upon markup in the loaded multimodal web page any document level grammars and loading the document level grammars identified by the markup.
6. The method of claim 5 wherein identifying in dependence upon markup in the loaded multimodal web page any document level grammars further comprises identifying a scope attribute for a VoiceXML form in an X+V document.
7. An apparatus for enabling global grammars for a particular multimodal application, the apparatus including a multimodal browser and a multimodal application operating on a multimodal device supporting multiple modes of user interaction with the multimodal application, the modes of user interaction including a voice mode and one or more non-voice modes, the apparatus comprising a computer processor and a computer memory operatively coupled to the computer processor, the computer memory having disposed within it computer program instructions capable of:
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, loading any currently unloaded global grammars in the loaded multimodal web page and maintaining any previously loaded global grammars; and
if the loaded multimodal web page is not one of the plurality of multimodal web pages of the particular multimodal application, unloading any currently loaded global grammars.
8. The apparatus of claim 7 , wherein the computer program instructions capable of determining whether the loaded multimodal web page is one of a plurality of multimodal web pages of the particular multimodal application further comprise computer program instructions capable of comparing a base URI for the particular multimodal application with a designated URI in the loaded multimodal web page.
9. The apparatus of claim 7 , wherein the computer program instructions capable of loading any currently unloaded global grammars in the loaded multimodal web page further comprise computer program instructions capable of:
identifying in dependence upon markup in the loaded multimodal web page a global grammar;
determining that the identified global grammar is not currently loaded; and
loading the identified global grammar.
10. The apparatus of claim 9 , wherein the computer program instructions capable of identifying in dependence upon markup in the loaded multimodal web page a global grammar further comprise computer program instructions capable of identifying a scope attribute for a VoiceXML form in an X+V document.
11. The apparatus of claim 7 , further comprising computer program instructions capable of identifying in dependence upon markup in the loaded multimodal web page any document level grammars and computer program instructions capable of loading the document level grammars identified by the markup.
12. The apparatus of claim 11 , wherein the computer program instructions capable of identifying in dependence upon markup in the loaded multimodal web page any document level grammars further comprise computer program instructions capable of identifying a scope attribute for a VoiceXML form in an X+V document.
13. A computer program product for enabling global grammars for a particular multimodal application, the computer program product including a multimodal browser operating on a multimodal device supporting multiple modes of user interaction with the multimodal application, the modes of user interaction including a voice mode and one or more non-voice modes, the computer program product disposed upon at least one recordable computer-readable medium, the computer program product comprising computer program instructions capable of:
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, loading any currently unloaded global grammars in the loaded multimodal web page and maintaining any previously loaded global grammars; and
if the loaded multimodal web page is not one of the plurality of multimodal web pages of the particular multimodal application, unloading any currently loaded global grammars.
14. The computer program product of claim 13 , wherein the computer program instructions capable of determining whether the loaded multimodal web page is one of a plurality of multimodal web pages of the particular multimodal application further comprise computer program instructions capable of comparing a base URI for the particular multimodal application with a designated URI in the loaded multimodal web page.
15. The computer program product of claim 13 , wherein the computer program instructions capable of loading any currently unloaded global grammars in the loaded multimodal web page further comprise computer program instructions capable of:
identifying in dependence upon markup in the loaded multimodal web page a global grammar;
determining that the identified global grammar is not currently loaded; and
loading the identified global grammar.
