38. The method of claim 18 , wherein the input communication from the user represents a request for at least one of a set of predetermined task objectives.
18. A method of task classification using a phonotactic model built for domain independent speech recognition, comprising: recognizing phones from a user's input communication using a current phonotactic model stored in a database; detecting morphemes from the recognized phones; creating, via a processor, a new phonotactic model using the detected morpheme, the creating the new phonotactic model comprising transforming a prior probability distribution associated with a first domain to a prior probability distribution associated with a second domain; replacing the current phonotactic model with the new phonotactic model in the database; and making a task-type classification decision based on the detected morphemes from the user's input communication.
