Assessment and Prediction of Speech Quality in Telecommunications

Mehr zum Buch

The book delves into the intricate relationship between telecommunication voice service quality and transmission systems, emphasizing the multidimensional nature of quality perception. It introduces a schematic classification of factors affecting quality, including conversational and user-related contributions. A real-time simulation model is developed to manipulate key transmission parameters and predict mouth-to-ear quality based on measurable elements. Additionally, it provides an in-depth analysis of the SUBMOD and E-models, focusing on their psychoacoustic and psychophysical foundations, aiding network planners in quality estimation.
