1. A method of monitoring language understanding of a user'"'"'s input communication in an automated dialog system, comprising:

  • determining whether a probability of understanding the user'"'"'s input communication exceeds a first threshold, wherein if the first threshold is exceeded, further dialog is conducted with the user and if the first threshold is not exceeded, the user is routed to a human for assistance; and

    determining whether a probability of understanding the user'"'"'s input communication exceeds a second threshold, the second threshold being greater than the first threshold, wherein if the second threshold is exceeded, further dialog is conducted with the user using a current dialog strategy and if the second threshold is not exceeds, further dialog is conducted with the user using an adapted dialog strategy.
