Abstract
The article proposes an objective method of calculating the intelligibility of speech in the room based on the assessment of the values of the interaural correlation coefficients in the listening position. The method can serve as an a priori assessment of language intelligibility already at the design stage of the room, as well as be used for stereo and monophonic sound sources.
Calculations are performed to emit rectangular and sawtooth video pulses. Comparison of the obtained results with the results of articulation tests in the studied hall testifies to the expediency of using a sawtooth video pulse for analysis. On the basis of the established scale of correspondence of articulatory intelligibility of language and coefficients of interaural correlation, the intelligibility of language indoors is defined.

Keywords
speech intelligibility, methods of assessing speech intelligibility, correlation coefficient, localization of sound, stereo sound.
