dcterms:description
The primary objective of this paper is to deepen the methodology for objective quantification of the quality of transmission through the impairment factors closely associated with the utilization of wideband speech codecs in telecommunication networks. This methodology is based on subjective auditory listening-only tests, but the resulting impairment factors may be used for predicting speech quality in an instrumental way, e.g., for network planning purposes. The derived impairment factors fit into the common framework which is defined in recommendations by the E-model for narrowband telephone networks, and which is hereby extended towards wideband speech transmission.
