METHOD FOR SELECTING FUNDAMENTAL TONE FROM SPEECH SIGNAL Russian patent published in 2002 - IPC

Abstract RU 2184399 C2

FIELD: acoustic engineering. SUBSTANCE: method involves expanding speech signal in a sequence of Fourier spectra, finding absolute maximum, calculating mean value the obtained maximum sequence argument, evaluating mean frequency of the fundamental tone of the speech signal under study, amplitude signal selection, calculating autocorrelation matrix determinant values and filtering the values. EFFECT: high accuracy of the method. 2 cl, 1 dwg
