1. A method comprising
measuring distances between vectors that represent an utterance and vectors that represent a template,
generating additional information including a frequency measure based on the measured distances, the additional information
indicative of how well the vectors of the utterance match the vectors of the template, and
making a matching decision based on the measured distances and on the generated additional information.
