Patent ID: 8725512

Claim:
A method of configuring a system to perform spoken dialog confirmation, comprising: operating at least one programmed processor to perform: classifying a plurality of spoken dialog hypotheses into a plurality of classes of spoken dialog hypotheses, each of the plurality of spoken dialog hypotheses being a potential semantic interpretation that a semantic interpreter is able to output as a result of a semantic interpretation process performed on an input, the plurality of classes comprising a first class of spoken dialog hypotheses comprising at least one first spoken dialog hypothesis and a second class of spoken dialog hypotheses comprising at least one second spoken dialog hypothesis, the at least one first spoken dialog hypothesis being different from the at least one second spoken dialog hypothesis; and determining, for each of said plurality of classes of spoken dialog hypotheses, a threshold for use in evaluating a confidence level of the semantic interpreter in an output of the semantic interpreter that comprises one of the one or more hypotheses in the class, wherein the determining comprises determining a first threshold for the first class and a second threshold for the second class, the first threshold having a different value than the second threshold, wherein the determining comprises adjusting the first threshold based at least in part on a number of times the at least one first spoken dialog hypothesis was previously output by the semantic interpreter.
