A method and system of compiling and caching voice application documents in order to provide more efficient retrieval of resources in a web-programming model such as in the VoiceXML domain. The method and system of the present invention requires that a voice application resource such as a VoiceXML document first be transformed into a representative object model before it is stored in the system's cache memory, and that this model becomes the voice application resource that is ultimately executed by the VoiceXML interpreter. The representative object model contains all of the data of the original source document but in a compressed and optimized format therefore occupying a smaller footprint in memory. The representative object model also contains the code necessary to execute the data. Further, the compressed representative object model does not need to be compiled again before execution. Because the object model stored in cache contains a compiled representation of the original resource and not the original resource itself, it can be executed as a binary object, thus leading to greater efficiency during execution and the reduction of cost and hardware utilization.
