10. The method of claim 9 wherein the comparing comprises: representing a voice sample as one of a MFC coefficient vector and a feature vector; computing at least one of a Euclidean distance and a correlation measure from the representation; and outputting at least one best matching sample in probability order having at least one of a low Euclidean distance and a high correlation measure.
