  abstract =     "The main aim of this study is to develop a
                 low-complexity non-intrusive quality prediction model
                 in Voice over Internet Protocol (VoIP) systems. In
                 order to gain this goal, a 2-level structure for
                 predicting the quality of speech is proposed.
                 Furthermore, the capabilities of multi-gene genetic
                 programming are investigated through developing a
                 number of parallel models and different feature
                 vectors. These models are used in two hierarchical
                 levels to construct the final model. To consider the
                 transmission media and speech signal characteristics in
                 quality measurement process, both network impairments
                 and per-frame features are employed simultaneously for
                 developing models. Several experiments are performed
                 based on the proposed structure while different
                 combinations of speech feature types in the cases of
                 noise free and noisy speech signals are examined. The
                 obtained results indicate that using parallel models in
                 a 2-level structure enhances the accuracy of derived
                 models as compared with 1-level structure and common
                 single-gene GP models.",
