Venkatraman Atti, Daniel J. Sinder, Shaminda Subasingha, Vivek Rajendran, Duminda A. Dewasurendra, Venkata Chebiyyam +6

ICASSP 2015accepted

A highly error resilient mode of the newly standardized 3GPP EVS speech codec is described. Compared to the AMR-WB codec and other conversational codecs, the EVS channel aware mode offers significantly improved error resilience in voice communication over packet-switched networks such as Voice-over-…

Super-wideband bandwidth extension for speech in the 3GPP EVS codec

Venkatraman Atti, Venkatesh Krishnan, Duminda A. Dewasurendra, Venkata Chebiyyam, Shaminda Subasingha, Daniel J. Sinder +6

ICASSP 2015accepted

This paper describes the time-domain bandwidth extension (TBE) framework employed to code wideband and super-wideband speech in the newly standardized 3GPP EVS codec. The TBE algorithm uses a nonlinear harmonic modeling technique that incorporates principles of time-domain envelope-modulated noise m…
