Abstract

A system is provided for dynamically converting non-voice enabled documents into voice enabled pages written in VoiceXML without the need for manually coding the document into VoiceXML. The system includes a voice server for accepting the original document, a data server for accepting said HTML document; a run time engine for applying an XSLT translator to such HTML document as well as any requisite data information rendering a VoiceXML version of the original document without the need to manually code such document. It will be appreciated that the system can be used to dynamically convert other non-voice enabled documents.

Claims

1. A system for converting an original document written in a non-voice enabled language into a voice enabled document, said system including means for communicating with a potential user and means for dynamically converting said original document into a voice-enabled document by the application of an XSLT translator without the need to manually code such voice-enabled document.

2. The system of claim 1, wherein the original document is converted into a VoiceXML document.

3. The system of claim 1, wherein the original document is a web page written in HTML.

4. The system of claim 1, wherein the original document is the product of a database query.

5. The system of claim 1, wherein said means for communicating comprises a VoiceXML browser that parses VoiceXML and handles all speech recognition and text to speech operations.

6. The system of claim 5, wherein said VoiceXML browser is contained on a voice server.

7. The system of claim 6, wherein said voice server is a Windows server.

8. The system of claim 5, where said means for dynamically converting comprises:

a converter for establishing a particular speech sequence and means for entering XSLT rules; and

a run time engine for;

receiving a request from said voice browser, obtaining a non-voice enabled document to be converted, applying the XSLT rules from said converter, converting said non-voice enabled document into a voice-enabled document by applying said XSLT rules and outputting the converted document to said voice server.

9. The system of claim 8, further including an external data source containing the original document to be converted.

10. The system of claim 8, wherein said converter is a Windows tool that can create XSLT translations.

11. The system of claim 10, wherein said converter runs on a Windows developer workstation.

12. The system of claim 8, wherein said run time engine is a set of code written in Java running as a servlet application.

13. A system for converting an original document written in a non-voice enabled language into a voice enabled document, said system including:

a voice server for communicating with a potential user;

a converter for establishing a particular speech sequence with a potential user;

means for accessing an external data source containing said original document; and

a run time engine for dynamically converting said original document into a voice-enabled document by the application of an XSLT translator from said converter without the need to manually code such voice-enabled document.

14. The system of claim 13, wherein said run time engine includes:

means for receiving a request from said voice server;

means for obtaining said non-voice enabled document from said external data source;

means for applying XSLT rules from said converter and convert said non-voice enabled document into a voice enabled document; and

means for outputting the converted document to said voice server.

15. A method for dynamically converting a non-voice enabled document to a voice enabled document, said method comprising the steps of:

providing a non-voice enabled document from an external data source;

establishing predetermined XSLT translation rules and a speech sequence and introducing said rules and speech sequence into a data server having a run time engine;

receiving a voice request from a user through a voice server;

communicating the voice request to said run time engine from said voice server;

receiving the appropriate non-voice enabled document from said external source and dynamically converting it into a voice-enabled document by applying the predetermined XSLT translation rules; and

communicating said voice-enabled document to said voice server.

16. The method of claim 15, wherein said non-voice enabled document is a web page written in HTML.
