Primary analysis of speech signals
Victor N. Sorokin, D. N. Chepelev · Acoustical Physics · 2005
Operations of the type of taking the logarithm, summation, and time delay can be used by a simple operator, which, with different values of frequency and time parameters, creates different transformations of the current spectrum. This operator simulates such properties of auditory perception as temporal and frequency masking, effects of turning on and off a stimulus, selective response to transients with different rates, detection of amplitude and frequency modulations, and adaptation to the mean signal level.
