Patent ID: 7085717

Claim:
A method comprising measuring first distances between (a) vectors belonging to a set of vectors that represent an utterance and (b) vectors belonging to a set of vectors that represent a template, the measuring being done in accordance with a first order of the utterance vectors and a first order of the template vectors, and measuring second distances between (a) vectors belonging to the set of vectors that represent the utterance and (b) vectors belonging to the set of vectors that represent the template, the measuring being done in accordance with a second order of the utterance vectors and a second order of the template vectors, in which the first template vector order and the second template vector order are different and/or the first utterance vector order and the second utterance vector order are different, and in which the measure of first distances is outside of a pre-specifled threshold, and the measure of second distances indicates that the template represents an out-of-vocabulary utterance.
