  • Abstract
    This paper discusses the voice and audio quality characteristics of EVS, the recently standardized 3GPP codec. Especially frame erasure conditions were evaluated. Comparison to industry standard voice codecs: 3GPP AMR and AMR-WB as well as direct signals at varying bandwidths was made. Speech quality was evaluated with two subjective listening tests containing clean and noisy speech in Finnish language. Five different random frame erasure rates were evaluated: 0 %, 3 %, 6 %, 10 % and 15 %. Nine-scale subjective mean opinion score was calculated for all tested conditions.
