FIELD: automation engineering. SUBSTANCE: method involves filtering-out the basic maximum points of time-dependent function of initial speech signal. Maximum search is to be blocked for single blocking interval after the selected maximum. Descending signal is formed after the blocking pause is over lowering relative to the selected maximum. The descending signal is generated with its maximum value exceeding the absolute maximum of the basic signal over the basic tone time interval under analysis. EFFECT: higher reliability in detecting basic maximums of the initial signal time function. 7 cl, 154 dwg, 15 tbl
