QoS Estimation and Prediction of Input Modality in Degraded IP Networks

This paper evaluates the impact of combined transcoding and packet loss degradation on speech as input for the interactive voice response service (IVR) and proposes a method for classification of user input according to speech quality. Careful optimization of a communication system and all of its se...
