ABSTRACT
Available objective Quality of Experience (QoE) assessment methods for speech and audio quality evaluation are not directly usable for quality rating of professional broadband audio communication applications over IP such as audio contribution links for broadcasting. To fill this gap, we designed a dedicated non-intrusive parametric QoE model for conversational quality rating based on the E-model approach. With this the QoE of Audio Contribution over IP (ACIP) can be monitored. Moreover, the estimated QoE scores can be used for a perceptually-driven Quality of Service (QoS) optimization for ACIP, which has different requirements and characteristics compared to Voice over IP (VoIP). In this paper, we present our ACIP QoE model and propose an objective QoE metric for assessing the listening-only quality in ACIP. The latter is used by us for intrusive QoE evaluations, which are necessary for the derivation of a parametric QoE model. Our experimental methodology is illustrated in depth and we give exemplified results. Finally, we demonstrate the application of our model in perceptually-driven QoS optimization.

A cost-effective and real-time QoE evaluation method for multimedia streaming services
Traditionally, subjective tests are conducted to obtain the Mean Opinion Score (MOS) or Quality of Experience (QoE) of a video streaming service. However, subjective tests are time-consuming and rather costly. Thus, a cost-effective and real-time QoE ...
On the Use of Objective Quality Measures to Estimate Watermarked Audio Quality
IIH-MSP '12: Proceedings of the 2012 Eighth International Conference on Intelligent Information Hiding and Multimedia Signal ProcessingThis paper compares two objective audio quality assessment measures calculated for three watermark methods with its corresponding subjective measures. The aim was to see if these measures could be used to estimate the subjective quality of audio with ...
