Measuring Perceptual VoIP Speech Quality over UMTS

Roland Kwitt, Thomas Fichtel, Thomas Pfeiffenberger (2006): Measuring Perceptual VoIP Speech Quality over UMTS In: Internet Performance, Simulation, Monitoring and Measurement. Proceedings of IPS-MoMe 2006, Salzburg, Austria

Abstract: This paper focuses on VoIP speech quality measurements over a 3G UMTS network, by means of perceptual quality models. We present conducted measurement results and point out that perceptual measurements are a necessity when it comes to evaluating the capability of wireless networks for VoIP transmissions, since they provide measures for the impact of the network on the perceived speech quality.
