Dialog management in a conversational computer system

摘要

A method for determining and maintaining dialog focus in a conversational speech system includes presenting a command associated with an application to a dialog manager 14. The application associated with the command is unknown to the dialog manager at the time it is made. The dialog manager 14 determines a current context of the command by reviewing a multi-modal history of event 16. 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.
