Objective Assessment of the Quality of Transmission and Informativeness of a Speech Signal According to Statistical Parameters
Abstract
In this paper, the possibility of an objective assess- ment of the quality of the transmission of a speech signal (SS) is discussed based on the use of the complex statistical estimation method. The statistics of the energy parameter SS - relative average power (RAP) is investigated. Comparison of RAP for SS estimates and transmission quality on the MOS scale con?rms the possibility of predicting transmission quality by the median RAP value of channel. A study of the informativeness of speech signals by their statistical parameters. The statistical characteristics of the speech signals of speakers, which are used as lecture notes by leading lecturers of the "Radio and Television" Faculty of MTUCI, are studied. A number of recommendations have been formulated for optimizing the selected parameters in order to improve the perception of information by the audience.
