【 摘 要 】

The purpose of this study is to survey an improvement of the voice information security estimating method on the basis of immediate appreciation tests with connected texts results. Estimation of voice information protection from leakage through information leakage canals is necessary for certification of informatization objects, and for efficiency control of protection means and systems. A word legibility coefficient (W) is the main quantitative criterion of voice information security. Its instrument estimation is based on the Pokrovskiy's experimental tests results. As we think, the main flaw of the speech intelligibility instrumental estimation method is the absence of testing with connected texts. This should lead to an increase of real speech intelligibility relatively the method estimation. The paper shows the imperfection of the method of Pokrovskiy's for connected texts.
