Claim 4:
4. The method according to claim 1 , wherein said evaluating further comprises calculating two or more progressive similarity scores each with respect to a different instant during the progress of a real-time conversational media session, wherein each of said scores corresponds to the similarity between the significant attributes associated with the real-time conversational media session data available at the corresponding instant and the reference data, and wherein said evaluating further comprises evaluating progressive similarity between the real-time conversational media session data and the reference data based upon the two or more progressive similarity scores.
