1. A method for building a phonotactic model 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 new processor, a new phonotactic model using the detected morphemes, 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 outputting the detected morphemes for processing.
