Abstract: A speech recognition manager receives representations of one or more words from a speech decoding system and interprets the received words based upon the current context state so as to provide extremely accurate, flexible, extendable and scalable speech recognition and interpretation. The speech recognition manager limits the number of words that the speech decoding system can recognize in a given context state in order to increase the speed and accuracy of the speech recognition process. Whenever the context state changes, the manager loads a new list of words that can be recognized for the new context state into the speech decoding system so that while the speed and accuracy of the speech recognition process is increased, the total grammatical structure recognized can be easily increased as well.
