Vodacom’s super HD voice calling: what makes it different?

Mobile distributor Vodacom recently announced the introduction of super high-definition voice calling to its service. Also called HD Voice+, Vodacom is collaborating with mobile manufacturers to incorporate the new technology, which succeeds the current HD voice codec, adaptive multi-rate wideband (AMR-WB).

The new technology uses voice-over-LTE (VoLTE) to deliver speech quality that is on the same level as high-fidelity stored music, and can offer CD quality sound with 20 kHz of audio bandwidth.

Vodacom says that improved voice quality will provide coverage gains to cell-edge users, resulting in better voice quality performance in areas where coverage might not be optimal.

If you are in doubt as to whether Vodacom’s HD Voice+ really improves your mobile experience, check out the video below, demonstrating the difference between non-HD voice calling and HD voice calling, keeping in mind that HD Voice+ will offer sound quality that is exponentially better than its predecessor.
