Enhanced Voice Services Codec for LTE

By Kari Järvinen, Chairman, TSG SA WG4

3GPP SA4 has completed work on the Enhanced Voice Services (EVS) Codec, in Release 12, to enable vastly improved voice quality, network capacity and advanced features for voice services over LTE and other radio access technologies standardized by 3GPP. 

EVS is the first 3GPP conversational codec offering up to 20 kHz audio bandwidth, delivering speech quality that matches other audio input such as stored music, while offering high robustness to delay jitter and packet losses.

Designed to meet the demands of packet-switched mobile communications networks, the EVS codec has been developed and standardized under the lead of the 3GPP Codec Working Group, 3GPP TSG SA WG4.
