Abstract: For the purposes. of speech synthesis, biometrics , medical and psychological diagnosis, the functioning of the glottis during phonation has been studied many times. At present, a relatively trivial solution proposed by Fant has established itself, regardless of the actual purpose of the system, using the "pusle source - filter" model. The model of Fant allows the linear prediction method to perform reconstruction of the current form of the vocal tract and the excitation of glottal volume velocity. But the practice shows that the fluctuations of the speech tract due to psycho-physiological effect on the functioning of the facial muscles in most cases are negligible. Thus, they are below the accuracy, which the linear model allows, using approximation with a cascade of coaxial cylindrical sections of equal length and constant cross-section. This requires more complex algorithms, and thus additional information is extracted from the pattern of air volume velocity after glottis. In this study, it is to be shown, that the model of Fant actually allows depiction of the psychophysiological changes in the spectral features of the speech signal without the use of additional models. For this purpose it is sufficient to analyze the relationships of the main parameters of the excitation pulse of the source with the frequency response of the filter. In the current practice, these correlations are not considered and the source and the filter are examined separately. (More)
