EVS Channel Aware Mode Robustness to Frame Erasures
Abstract
This paper discusses the voice and audio quality characteristics of the EVS, the recently standardized 3GPP Enhanced Voice Services codec. Especially frame erasure conditions with and without channel aware mode were evaluated. The test consisted of two extended range MOS listening tests. The tests contained both clean and noisy speech in clean channel as well as with four frame erasure rates (5%, 10%, 20% and 30%) for selected codecs and bitrates. In addition to subjective test results some additional objective results are presented. The results show that EVS channel aware mode performs better than EVS native mode in high FER rates. For comparison also AMR, AMR-WB and Opus codecs were included to the listening tests.
