Speech fragment identification by means of integrated comparison criterion of momentary spectrums of speech signal

A simple voiced fragment identification method is proposed, by means of comparison of their momentary spectrum by minimal discrepancy of spectrum elements, having various information value. It is formulated integrated comparison criterion of momentary spectrums, taking into consideration “weight” of elements in accordance with their significance in identification of spectrum “image”. A “weight” defining method for each spectrum’s element in integrated criterion formula is given

Multimeter Method of Estimating the Similarity of the compared Frames of Speech Signal

Three methods of estimating the degree of similarity of the compared frames of speech signal are examined: parametric, correlated and linear prediction which are based on a signal’s peculiarities of spectral and wave representation. A comparative evaluation of its effectiveness is represented from the point of view of the results of the comparative truthfulness of two segments. A multimeter estimating method is proved through the example of checking its effectiveness for the restoration of real phonograms d

Analysis of Communication Channels Vulnerability From Listeniing Guaranteed by Band-Frequency Scramblers

Features of various scramblers which use only frequency transformation are considered. Recommendations of using analog scramblers for estimating it's vulnerability category for communication channels are proposed.
