Abstract: We suggest some new parameters for the description of short fragments of speech signals as well as methods for their estimation. We develop a technique for the exact localization of “explosion” in syllables beginning with stop consonants. A method for the evaluation of instantaneous frequency in the sound part of the syllable is presented. The method does not suppose the implementation of the Hilbert transform. It is shown that the distribution of instantaneous frequencies in a speech signal can be used for speaker identification.

Keywords: stop consonants, explosion localization, approximation of instantaneous frequency, distribution of instantaneous frequencies, speaker identification.
