“…Signal-based methods, as the name suggests, depend on digital signal processing that estimates the speech quality when the envelope of the speech signal suffered from degradation over time due to low-bit rate coding or transmission over noisy wireless links such as ITU-T recommendation P.563. On the other hand, parameter-based methods process the audio stream that is decoded after buffer playout to extract relevant information for estimating the voice quality such as the most prominent approaches E-model (ITU-T recommendation G.107) [20] and POLQA ITU-T recommendation P.863 (Perceptual Objective Listening Quality Assessment) [21].…”

“…So, the use of subjective methods, which are described in [6,7], allows to evaluate the QoE level mainly only at the moment when the audio and video information is subjected to distortions that occur during digitization, compression, transmission, decoding, etc. For example, for a video stream, these methods are based on subjective metrics such as Single-Stimulus Continuous Quality Evaluation (SSCQE), Double Stimulus Impairment Scale (DSIS) and Double Stimulus Continuous Quality Scale (DSCQS) [8,9]. And for the subjective assessment of the audio stream, Perceptual Speech Quality Measurement (PSQM) mechanisms are usually used [10,11].…”

“…POLQA, Perceptual Objective Listening Quality Assessment [4], covers a model to predict speech quality by means of digital speech signal analysis. The prediction of those objective measures should come as close as possible to subjective quality scores as obtained in subjective listening tests.…”

“…Two important quantitative metrics developed over the years are PESQ (Perceptual Evaluation of Speech Quality) [9][13] and POLQA (Perceptual Objective Listening Quality Assessment) [4] (and variations). This paper introduces a new method for evaluation of speech signal in mobile devices with no need of a reference signal or recognition as it is more natural to human perception.…”
