1. A voice application creation and deployment system comprising: a voice application sewer to create and serve voice applications to clients over a communication network; at least one voice portal node coupled to the communication network, the portal node to facilitate client interaction with the voice applications; and an inference engine executable from the voice application server, wherein the inference engine is activated at one or more predetermined points of an ongoing voice interaction, wherein the inference engine is configured to determine whether an inference of client need can be performed, this determination being based on analysis of real-time client data related to the interaction during a pre-determined point in an active call flow of the served voice application and further based on analysis of historical data associated with client interaction, the inference engine further configured to determine which inference dialog is executed and inserted into the call flow if an inference is appropriate.

The system of claim 1 wherein the inference engine causes an inference to occur at more than one time during the course of an interaction.
