Airtel launched HD voice service in Africa

Bharti Airtel in the month of March 2013 launched high quality voice service for its subscribers in Kenya, Rwanda, Malawi and Nigeria in the African sub-continent. 

The benefit of HD voice service is that, customers can talk normally and be heard clearly, without having to raise their voice, even in noisier environments.

Advantages of HD Service
• Mobile HD voice enables high quality voice calls because it reduces the 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.
