Abstract: A method and apparatus are provided for performing speech recognition using observable and meaningful relationships between words within a single utterance and using a structured data source as a source of constraints on the recognition process. Results from a first constrained speech recognition pass can be combined with information about the observable and meaningful word relationships to constrain or simplify subsequent recognition passes. This iterative process greatly reduces the search space required for each recognition pass, making the speech recognition process more efficient, faster and accurate.

Abstract: An apparatus and a concomitant method for natural language understanding. In one embodiment, the present invention provides a new architecture that employs a sophisticated natural language understanding parser in conjunction with a speech recognition component and a VoiceXML application.

Abstract: An apparatus and a concomitant method for speech recognition. In one embodiment, a distributed speech recognition system provides speech-driven control and remote service access. The distributed speech recognition system comprises a client device and a central server, where the client device is equipped with two speech recognition modules: a foreground speech recognizer and a background speech recognizer. The foreground speech recognizer is implementing a particular spoken language application (SLA) to handle a particular task, whereas the background speech recognizer is monitoring a change in the topic and/or a change in the intent of the user. Upon detection of a change in topic or intent of the user, the background speech recognizer will effect the routing to a new SLA to address the new topic or intent.

Abstract: A system, method and article of manufacture are provided for allowing concept based information searching. Textual information is collected utilizing a network. The textual information is parsed to create topic specific information packets, which are stored in an information cache. The system parses a user query and compares the parsed user query with the information packets in the information cache to locate matching information packets and displays the matching information packets to a user.

Abstract: A natural language information querying system includes an indexing facility configured to automatically generate indices of updated textual sources based on one or more predefined grammars and a database coupled to the indexing facility to store the indices for subsequent searching.
