Improved Accuracy Intrusive Method for Speech Quality Evaluation Based on Consideration of Intonation Impact

The article considers the problem of the effect of intonation in speech transmitted over communication networks on the results of intrusive methods for assessing quality. It is determined that a change in intonation makes changes in the parameters of the speech signal identical to communication networks. Based on the analysis of the features of the functioning of methods for assessing the quality of speech transmission, their classification by the criterion of intonation influence is proposed. The principles of perception by users of complex composite numbers, as well as the mechanism and causes of the occurrence of perception errors are investigated.
