The task of developing an algorithm of integrated assessment of speech quality at the output of communication channel by the action of acoustic noise is considered.
The aim is to develop an algorithm of complex estimation of speech quality at the output of communication channel, the results of which as much as possible are close to the results of subjective evaluation, prepared according to GOST 50840-95. In the process of evaluating the quality of speech such parameters as clarity, awareness, preservation of emotional color to vote are the most important criteria. In modern world it is very important to transmit the highest quality for comfortable communication and feelings of speaker's emotional state. As a result from all known algorithms of objective evaluation three algorithms were chosen, the results of which turned out to be mostly correlating with subjective evaluation prepared in accordance with GOST 50840-95. On their basis the algorithm of complex evaluation speech signals quality which will allow to automate the process of evaluating the characteristics of output speech transmission systems and to provide more accurate evaluation compared to known algorithms.

Keywords: speech, acoustic noise, subjective evaluation of quality of terminal equipment, data transmission systems, voice quality assessment algorithm.
