Abstract:
This paper presents the Mean Opinion Score (MOS) measurements results of an input stage of an adaptive speech based on Quality of Experience (QoE) control during a Voice Over Internet Protocol (VoIP) call. QoE is periodically determined by means of a modified version of E-model and recorded in a log file. At the end, we compared the results to POLQA (Perceptual Objective Listening Quality Assessment), and prove that continuously measurements are correct and can be used in the future real-time QoE controller to be build.
