Abstract

A method, system and voice browser execute voice applications to perform a voice-based function. A document is retrieved and parsed to create a parse tree. Script code is created from the parse tree, thereby consuming part of the parse tree to create a reduced parse tree. The reduced parse tree is stored in a cache for subsequent execution to perform the voice-based function.

Claims

1. A voice browser for executing voice applications to perform a voice-based function, the voice browser comprising:

a communication interface configured to retrieve an XML based document;

a memory; and

a processor communicatively coupled to the communication interface and memory, the processor configured to;

process the XML based document to create bytecode associated with the XML based document;

cause the bytecode associated with the XML based document to be stored in the memory; and

in response to receiving a request for the XML based document, process the stored bytecode associated with the XML based document to perform a voice based function.

2. The voice browser of claim 1, wherein the processing of XML based document includes:

parsing the XML based document to create a parse tree;

generating javascript code to reduce the parse tree; and

converting the javascript code to create the bytecode.

3. The voice browser of claim 2, wherein the bytecode is attached to the reduced parse tree to match at least one location within the XML based document from which the bytecode arose.

4. The voice browser of claim 1, wherein the processing of XML based document includes:

parsing the XML based document to create a parse tree, the parse tree including a plurality of commands;

generating javascript code for at least one command to reduce the parse tree; and

converting the javascript code to create the bytecode.

5. The voice browser of claim 1, wherein the voice browser coordinates a call among at least a first and second caller, the first caller joining the call, via the first request, before the second caller;

the processing of the XML based document and the causing of the bytecode to be stored in memory being caused in response to the first caller joining the call; and

the request being associated with the second caller joining the call.

6. The voice browser of claim 1, wherein the communication interface is configured to receive another request for the XML based document;

and

the processor is further configured to;

in response to receiving the other request, determine whether bytecode associated with the XML based document is stored in memory; and

in response to determining that the bytecode associated with the XML based document is stored in memory, process the stored bytecode associated with the XML based document to perform a voice based function.

7. The voice browser of claim 1, wherein the processor is further configured to:

receive a request for a second XML based document;

determine whether bytecode associated with the second XML based document is stored in memory; and

in response to determining that bytecode associated with the second XML based document is not stored in memory, process the second XML based document to create bytecode associated with the second XML based document and cause the bytecode associated with the second XML based document to be stored in the memory.

8. The voice browser of claim 7, wherein the processor is further configured to, in response to determining that the bytecode associated with the second XML based document is stored in memory, process the stored bytecode associated with the second XML based document to perform a voice based function.

9. A method for executing voice applications to perform a voice-based function, the method comprising:

retrieving an XML based document;

processing the XML based document to create bytecode associated with the XML based document;

storing the bytecode associated with the XML based document; and

in response to receiving a request for the XML based document, processing the stored bytecode associated with the XML based document to perform a voice based function.

10. The method of claim 9, wherein the processing of XML based document includes:

parsing the XML based document to create a parse tree;

generating javascript code to reduce the parse tree; and

converting the javascript code to create the bytecode.

11. The method of claim 10, wherein the bytecode is attached to the reduced parse tree to match at least one location within the XML based document from which the bytecode arose.

12. The method of claim 9, wherein a call is coordinated for at least a first and second caller, the first caller joining the call, via the first request, before the second caller;

the processing of the XML based document and the causing of the bytecode to be stored in memory being caused in response to the first caller joining the call; and

the request being associated with the second caller joining the call.

13. The method of claim 9, further comprising:

receiving another request for the XML based document;

in response to receiving the other request, determining whether bytecode associated with the XML based document is stored in memory; and

in response to determining that the bytecode associated with the XML based document is stored in memory, processing the stored bytecode associated with the XML based document to perform a voice based function.

14. The method of claim 10, further comprising:

receiving a request for a second XML based document;

determining whether bytecode associated with the second XML based document is stored in memory; and

in response to determining that bytecode associated with the second XML based document is not stored in memory, processing the second XML based document to create bytecode associated with the second XML based document and cause the bytecode associated with the second XML based document to be stored in the memory.

15. The method of claim 14, further comprising, in response to determining that the bytecode associated with the second XML based document is stored in memory, processing the stored bytecode associated with the second XML based document to perform a voice based function.

16. A method for executing voice applications to perform a voice-based function, the method comprising:

receiving a first request for an XML based document;

retrieving the XML based document in response to the first request;

processing the XML based document to create bytecode, the bytecode being associated with the first request;

storing the bytecode associated with the first request;

receiving a second request for the XML based document; and

in response to receiving the second request for the XML based document, processing the stored bytecode associated with the first request to perform a voice based function.

17. The method of claim 16, wherein the processing of XML based document includes:

parsing the XML based document to create a parse tree;

generating javascript code to reduce the parse tree; and

converting the javascript code to create the bytecode.

18. The method of claim 17, wherein the bytecode is attached to the reduced parse tree to match at least one location within the XML based document from which the bytecode arose.

19. The method of claim 16, further comprising:

receiving a request for a second XML based document;

determining whether bytecode associated with the second XML based document is stored in memory; and

in response to determining that bytecode associated with the second XML based document is not stored in memory, processing the second XML based document to create bytecode associated with the second XML based document and cause the bytecode associated with the second XML based document to be stored in the memory.

20. The method of claim 19, further comprising, in response to determining that the bytecode associated with the second XML based document is stored in memory, processing the stored bytecode associated with the second XML based document to perform a voice based function.
