Vodacom Launches Super HD Voice in South Africa

Vodacom South Africa is joining forces with a few device manufacturers to introduce the next phase that is sure to elevate the Vodacom network, Enhanced Voice Services (EVS) also known as the Super High Definition (SHD) voice or HD Voice+ in a live commercial network.

VoLTE subscribers who have a compatible handset on the Vodacom network can now have a much-improved voice clarity, thanks to the EVS codec.

Siyabonga Zulu, The Group Managing Executive for Radio Access Network Engineering of Vodacom, stated that Vodacom is always seeking innovative new ways to enhance the experience that customers have on the network, so installing Enhanced Voice Services would be a giant leap in the customer satisfaction process and would ensure even better voice quality for Vodacom’s 4G users. Zulu added that with Vodacom’s extensive 4G coverage, it now made sense to ensure that 4G users received the best possible voice quality to complement the network’s super-fast 4G speeds.

Three years ago Vodacom introduced VoLTE which was a free service and is now launching this ground-breaking technology in South Africa with EVS being the successor of the current HD Voice Codec that is called AMR-WB (Adaptive Multi-Rate Wideband).
This new Super HD Voice service is not free though, so it has been met with mixed reactions from the Vodacom customers so expected that the service would come at no extra charge, just like VoLTE.

EVS is designed to enable speech quality that matches audio sources like hi-fidelity stored music that offers up to 20kHz of audio bandwidth. In addition to that, EVS also provide coverage gains for cell-edge users in terms of much-improved voice quality performance in cell-edge conditions.

Vodacom’s intention with these latest enhancements to the network is to provide the highest performance possible for its customers.
