dc.description.abstract© 2021, Pleiades Publishing, Ltd.Mathematical models are proposed that make it possible to relate the parameters of a voice source with the parameters of the phase-frequency responses (PFR) of speech signal segments. In particular, it was found that the duration of operation of a source can be found from the average length of the intervals between the zeros and discontinuities of these PFR. For synthetic and real speech signals, based on the established properties of the phase response and the proposed heuristic methods for their analysis, a numerical estimate of the periods of the fundamental tone, the duration of the voice source within these periods, as well as the moments of the beginning Top and end Tcl actions of the voice source. The existence of the upper limit of the frequency range of the fundamental tone F0 within which the estimation error F0 does not exceed 5% is experimentally established. The average error in estimating the duration of a voice source using the proposed method for speech segments from the Arctic database was less than 0.3% for two speakers, and for a third speaker, it was 6.2%. It is shown that the error in determining values Top and Tcl depends on the properties of the voice source and increases significantly for F0 > 220 Hz. The most probable error in estimating quantities Top for three speakers from the Arctic database is estimated as 1.5, 10.2, and 13.5%; for Tcl, it is –9.7, –20.2, and –13.9%.
