Standardization of transmission quality measurements

The problems of evaluating the phonetic quality of speech and the characteristic features of a speaker’s articulatory base from the data of acoustic-phonetic measurements are considered. The evaluation is recommended to be performed using the GOST 50840-95 standard “Speech Transmission over Varied Communication Channels: Techniques for Measurement of Speech Quality, Intelligibility, and Voice Identification,” which was put into effect in Russia in 1997. Examples of experimental evaluation measurements in speech communication and criminalistic expertise are presented.
