Quality of oral speech reproduction using stochastic digital systems of information transfer at its statistical compaction is analyzed (on the example of Russian and Kazakh speeches) with the ratio of the speech signal power to the digitization and restoration noise power taken as quantitative characteristic of speech description. From an analysis of the results obtained it unambiguously follows that for analytical determination of the quality of speech message restoration using stochastic digital transfer systems it is expedient not to resort to approximations, but to use for estimation the experimentally obtained distribution of the probability of the number of successively rejected counts. The preference of the approach with alternating priority is established for a Russian speech message. In consideration of the Kazakh speech, the preference of the approach with alternating priority of the message is revealed. The approach with priority alternation in a count is the best of the three approaches being considered (with fixed priority, priority alternation in the transfer cycle Е1 and priority alternation in a count) for messages of the oral Russian and Kazakh speeches. This significant preference is explained by the influence of successive losses of more than one count on the ratio of the signal to noise power.
