Patent ID: 8095363

Claim:
A language understanding monitoring system that operates in a task classification system, comprising a task classification processor that is adapted to determine whether a task classification decision can be made based on an understanding of a user's input communication; a dialog manager that is adapted to conduct a dialog with the user; and a language understanding monitor that is adapted to determine whether a probability of understanding the users input communication exceeds a first threshold in the cases where a task classification decision cannot be made and, if the first threshold is exceeded, to prompt the dialog manager to conduct further dialog with the user, wherein the language understanding monitor is further adapted to determine whether a probability of understanding the user's input communication exceeds a second threshold, the second threshold being greater than the first threshold, and if the second threshold is exceeded, to prompt the dialog manager to conduct further dialog with the user using a current dialog strategy, and wherein at least one of said task classification processor, said dialog manager and said language understanding monitor performs that which it is adapted to do using a programmed processor.
