Paper Abstract

The paper describes development of a system, estimating sound signals quality, transmitted via communication channel, compressed, restored or processed. A brief review of the known methods of sound quality estimation is given together with the objective necessity of such system for modem telecommunications. The paper examines general outline and the basic components of the system - signal, synchronization and analytical components. Test signal (including statistic speech model) and sound perception models are considered. Based on the results of comparison of received analytical and subjective MOS estimations the paper makes conclusion about the adequacy of analytical estimations. The contribution also presents means of acoustic model perfection and software developed as well as different applications of the proposed system.
