Airtel becomes the third operator to launch a mobile HD voice service in Africa, the company said in a statement. “The company aims to make HD voice a reality on the continent. Further launches will be scheduled in 2013,” it added.
HD voice offers crystal clear audio quality and will enhance user experience. “Surveys confirm that customers place a high value on HD
Voice”, said Andre Beyers, Chief Marketing Officer, Airtel Africa.
Mobile HD Voice enables high-quality voice calls because it reduces background noise often heard on a regular call. The service is based on AMR (adaptive multi rate) Wideband technology (W-AMR) that operates with nine different bit rates, providing high-quality voice calls.
Compared to the current narrowband speech codec, the W-AMR speech-compression algorithm doubles voice bandwidth and produces better results.
