A speech analysis system, including a kurtosis module for processing a coded sound signal to generate kurtosis measure data; a wavelet module for processing the coded sound signal to generate wavelet coefficients; and a classification module for processing the wavelet coefficients and the kurtos is measure data to generate label data representing a classification for the coded sound signal. The sound signal is classified as environmental noise, silence, speech from a single speaker, speech from multiple speakers, speech from a single speaker plus environmental noise, or speech from multiple speakers plus environmental noise. Speech is further classified as voiced or unvoiced.
