Annotations languages:

The method of determination of frequencies of formant of vocal signal is developed on the output of comb of полосовых filters, allowing to improve exactness of phonematic of brief spectral analysis of vocal fragments, passed in the networks of packages with losses. For this purpose for the receipt of the proper system of equalizations of maximal verisimilitude the mathematical vehicle of the grouped selections, allowing to take into account a fact discrete, is used, in a frequency range, presentations of energy of vocal signal at the estimation of middle frequencies of formant of vocal signal.
Keywords: formants of vocal signals, phonematic brief spectral analysis of vocal signals, grouped selections, local expected value
