Dual Perspectives to the Assessment of Quality of Service of Transmitted Speech

Patrick O. Olabisi; Adeboye Olatubosun
In estimating the Quality of Service (QoS) of transmitted speech which has definitely suffered degradations under a number of network conditions, network approach has mostly been utilized in several applications. The perceptual approach which is user-centric and entirely does not depend on the network covers End-to-End assessment of what happen at all nodes and platforms of the network. This work evaluated both approaches and found ways of correlations between them and the difference approaches of subjective and objective with values ranging between 0.848 and 0.871. Prediction errors ranged between 0.4264 and 0.4825.
