1. A method for speech versus non-speech classification, comprising: receiving a two channel signal; computing a standard deviation of the separations between peaks in correlated content of the two channel signal; computing a loudness ratio of minimum and maximum values of recent data frames; computing a comparison of the energies of the two channels of the two channel signal; classifying the input signal content as speech or as non-speech based on the standard deviations, the loudness ratio, and the comparison of the energies of the right and left channels; providing the classification to signal processing for the two channel signal; processing the two channel signal based on the classification of the two channel signal; providing the processed signal to at least one transducer; transducing the two channel signal by the at least one transducer to produce sound waves.
