Abstract: In embodiments of the present invention, capabilities are described for understanding and responding to the user intent and questions quickly wherein the understanding is based on supervised system learning, Intelligent layered semantic and syntactic information processing and personalized adaptive semantic interface. Supervised system learning creates reference pattern set for the intent repository and possible question categories. Each layer in the layered processing increases the probability of the intent/question recognition. Personalized adaptive voice interface learns from user's interactions over time by enriching the pattern sets and personal index for successfully resolved user intents and questions. Collectively, all these technologies improve the response time for correctly recognizing and responding to user's intents and questions.
