Speaker Count Determination

Abstract

Speaker count is the process of automatically identifying segments of speech that contain multiple speakers before attempting to apply any co-channel interference reduction schemes. By computing the variance of the pitch estimate, a heuristic approach is used to classify a 30 msec frame of speech as being from a single talker or from multiple talkers. Using TIMIT data, 79% of the frames were classified correctly.
