14. A non-transitory computer readable medium containing an executable program for conducting an interactive dialogue, where the program performs steps of: receiving a first audio input signal from a user, the first audio input signal comprising a first set of one or more words; processing the first audio input signal so as to recognize the first set of one or more words in accordance with a vocabulary comprising a collection of words and an associated set of probabilities corresponding to the collection of words; generating a first output signal responsive to the first audio input signal in accordance with the processing, the first output signal comprising a second set of one or more words, wherein the second set of one or more words includes at least one word that is not included in the first set of one or more words; adjusting at least one probability in the associated set of probabilities, the at least one probability corresponding to at least one word that is included in the second set of one or more words but is not included in the first set of one or more words, thereby producing an adjusted set of probabilities based on the first output signal; and processing a second audio input signal, received after the first output signal is outputted and comprising a third set of one or more words, so as to recognize the third set of one or more words in accordance with the vocabulary and the adjusted set of probabilities.

The non-transitory computer readable medium of claim 14 wherein the adjusting comprises: increasing the at least one probability corresponding to the at least one word that is included in the second set of one or more words but is not included in the first set of one or more words.
