METHOD FOR MEASURING MAXIMAL LEGIBILITY OF SPEECH Russian patent published in 2006 - IPC G10L15/00 H04R29/00 

FIELD: technology for measuring maximally possible legibility of speech under extremely unfavorable conditions, in the noise, for low signal/noise ratios, and is meant mainly for determining protection of objects during loss of speech information through several leaking channels simultaneously.

SUBSTANCE: in accordance to method, in receipt point K receivers of other signal types, formed by acoustic testing signals, for example, electric, magnetic, vibro-acoustic signals, are positioned, acoustic and aforementioned K signal types formed in receipt position at all N frequencies of testing signal and in pauses between same, are received and measured separately, on basis of results of measurements signal/noise ratios are determined at each frequency of testing signal by each one of acoustic and K other types of received signals, at each frequency of testing signal greatest one of signal/noise relations are selected, measured by acoustic and K other types of received signals, then - speech legibility grade is calculated on basis of greatest signal/noise ratios.

EFFECT: increased trustworthiness of speech legibility measurements.
