With the introduction of fullband speech coding the question arises what role frequency components above 14 kHz play in speech quality assessment. On the one hand, our results show that bandwidth limitation from 24 kHz down to 14 kHz is not audible t

Available bandwidth is still a limiting factor for mobile communication applications. Multisensory communication has already been identified as an possibility to moderate this limitation. One of the strengths of mobile communication lies in its combi

This paper deals with the intelligibility of speech coded by the STANAG 4591 standard codec, including packet loss, using synthesized speech input. Both subjective and objective assessments are used. It is shown that this codec significantly degrades
