The quality of speech transmitted through narrowband (300-3400 Hz) and wideband (50-7000 Hz) networks has been a topic of investigation for decades, and models which predict passively experienced transmission quality as well as interactive communication quality are largely available. With the advent of super-wideband (20-14000 Hz) speech communication services, the influence factors of the underlying systems change, and new prediction models become necessary to adequately plan and monitor communication quality as well as its underlying perceptual dimensions and technical root causes of degradations from signals and/or parameters from the network and terminals. The framework offers diagnostic as well as summative information for network planning, optimization and monitoring.
