Parameter-based prediction of speech quality in listening context—Towards a WB E-model
Alexander Raake, Sebastian Möller, Marcel Wältermann, Nathalie Côté, Juan-Pablo Ramirez · 2010
The paper presents a first version of a wideband E-model applicable to planning future telephone networks in a listening-only context. It allows to predict wideband speech quality under bandwidth restrictions and wideband and narrowband speech coding with and without transmission errors, including the quality impact due to noise. The paper presents the different model components and discusses their prediction performance for a large set of listening tests. Based on a discussion of the proposed listening model, an outlook on required future research including the conversational situation is provided.
