Vodacom South Africa announced on Thursday it is partnering device manufacturers to introduce the next chapter in the evolution of the Vodacom network, Enhanced Voice Services (EVS).
The EVS is also known as Super High Definition (SHD) voice or HD Voice+ in a live commercial network.
The operator said VoLTE subscribers using a compatible handset on its network can now experience improved voice clarity made possible by the EVS codec.
EVS can deliver speech quality that matches other audio sources such as hi-fidelity stored music and is designed to offer up to 20kHz of audio bandwidth (CD quality).
VoLTE, without EVS, offers more than double the bandwidth available over 2G voice, and is similar to 3G WB AMR codec (23.85). With the addition of EVS, the bandwidth is again increased, further improving speech quality when using EVS-SWB (Super Wideband).
“Vodacom is always looking to improve the experience customers have on our network. Deploying Enhanced Voice Services is another step in this process and will ensure even better voice quality for our 4G users,”
Siyabonga Zulu, Vodacom Group Managing Executive for Radio Access Network Engineering, says.
“With our extensive 4G coverage, it makes sense to ensure that 4G users get the best possible voice quality to complement our super-fast 4G speeds.”
