Last Updated: Tuesday, March 5, 2013 - 16:45

New Delhi: Bharti Airtel on Tuesday announced the launch of high quality voice service for its subscribers in Kenya, Rwanda, Malawi and Nigeria in the African subcontinent.

"Airtel becomes the third operator to launch a mobile HD voice service in Africa. Further launches will be scheduled in 2013," the company said in a statement.

With HD voice, customers can talk normally and be heard clearly, without having to raise their voice, even in noisier environments.

"Surveys confirm that customers place a high value on HD voice," Airtel Africa Chief Marketing Officer Andre Beyers said, adding, "the new service will enrich end-user experience for Airtel subscribers".

Mobile HD voice enables high-quality voice calls because it reduces background noise often heard on a regular call.

It is based on AMR (Adaptive Multi Rate) wideband technology (W-AMR) which operates with nine different bit rates, providing high-quality voice calls.

Compared to the current narrow-band speech codec device, the W-AMR speech-compression algorithm doubles voice bandwidth and produces better results.
