Abstract: In accordance with the invention, a method and system for accessing a dialog system 101 employing a plurality of different clients 100, includes providing a first client device for accessing a conversational system 300 and presenting a command to the conversational system 300 by converting the command to a form understandable to the conversational system. The command is interpreted by employing a mediator 302, a dialog manager 303 and a multi-modal history 304 to determine the intent of the command based on a context of the command. A second client device is determined based on a predetermined device preference stored in the conversational system. An application is abstracted (400) to perform the command, and the results of the performance of the command are sent to the second client device.

Abstract: A system and method of the present invention for determining and maintaining dialog focus in a conversational speech system includes presenting a command associated with an application to a dialog manager. The application associated with the command is unknown to the dialog manager at the time it is made. The dialog manager determines a current context of the command by reviewing a multi-modal history of events. At least one method is determined responsive to the command based on the current context. The at least one method is executed responsive to the command associated with the application.

Abstract: An apparatus for automatically identifying command boundaries in a conversational natural language system, in accordance with the present invention, includes a speech recognizer for converting an input signal to recognized text and a boundary identifier coupled to the speech recognizer for receiving the recognized text and determining if a command is present in the recognized text, the boundary identifier outputting the command if present in the recognized text. A method for identifying command boundaries in a conversational natural language system is also included.
