FIELD: physics, acoustics.
SUBSTANCE: invention relates to speech analysis systems and can be used in speech recognition and synthesis means. The method is based on generating a likelihood ratio composite function logarithm using an input speech signal, finding the absolute maximum of the likelihood ratio composite function logarithm and calculating the argument of the absolute maximum of the likelihood ratio composite function logarithm.
EFFECT: high accuracy of estimating base frequency of a speech signal.
