This paper proposes a new signal-aware parametric quality assessment model for audio and speech over IP. The perceptual importance of the reproducing packets and relevant neighborhoods are included in the model. The model is developed from a built audio and speech quality assessment framework using the Artificial Neural Networks(ANN). The overall quality is evaluated by combining the signal-aware parameters with network parameters using a large set of audio and speech samples. It is shown that the signal-aware approach gains higher correlation with the improved PEAQ outputs compared with other parametric method such as E-model.
