Method and system for interactive conversational dialogue for cognitively overloaded device users

摘要

A dialog system, comprising: a knowledge base to store information regarding a device and a domain, and to categorize the information in at least one of a relational and a ontological manner; a device/application manager to isolate and encapsulate the device information for a plug-n-play of the domain; a speech recognition module to receive speech from a user and convert the speech into a word sequence, and to recognize at least one of full and partial proper names; a natural language understanding module to identify meaning structures from the word sequence using a statistically dependent model of the domain, and to adjust a boundary of the at least one of the full and partial proper names; a dialogue management module to interpret the meaning structures in a context of the conversation using the device information, and to construct a content of a response; a response generation module to select content and generate the response based on the context and grammatical rules; and a speech synthesis module to synthesize speech wave forms for the response.
