METHOD FOR DETECTING PAUSES IN SPEECH SIGNALS AND DEVICE FOR ITS REALIZATION

摘要

FIELD: speech recognition.;SUBSTANCE: in accordance to the invention, digitization is performed with signal step Δt, a flow of counts of signal of a certain length is recorded in memorizing device from microphone output in narrator silence mode, divided on a row of R long sections, range (1/Δt) of Fourier energy spectrum of each one of these sections is divided onto a row of frequency intervals (i=1,...,N), values P_{i pause} are computed, corresponding to each one of the intervals, computed average values P_{ipause av} are recorded into memorizing device, in case of incoming speech signal, values P_i are computed, ratios P_i to P_{i pause av} are computed in each one of N frequency intervals of all R long sections and max(P_i/P_{i pause av}) are determined, which are compared to threshold value h, determined in threshold computation circuit and at max(P_i/P_{i pause av})≤h decision is made about presence of pause, then value P_{i pause av} is renewed with consideration of current value of P_{i pause}.;EFFECT: reduced volume of memory for storing speech and reduced traffic during transmission thereof.;2 cl, 5 dwg
