Beerends, J.G. Publication year 2017 Abstract 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 intelligibility when compared to a standard narrowband filtered version of the synthesized speech. Packet loss impact is strongly dependent on the exact timing location. Furthermore it is shown that POLQA Intelligibility, a speech intelligibility prediction model, is capable of providing good intelligibility predictions for all investigated conditions. © 2017 The Author(s).
