Airtel starts HD voice service in Africa
current affairs in 2013
March 6th, 2013
Bharti Airtel has launched high quality voice service for its
subscribers in Kenya, Rwanda, Malawi and Nigeria in the African
sub-continent. What is HD voice and how is it better?
Mobile HD voice is high quality voice service which enables high quality voice calls as it cuts down the background noise often heard on a regular call. This service 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.
