Orange launches HD Voice service


Orange is the first network in the UK to announce the launch of HD Voice this year.

The service will be made available to HD Voice enabled handsets. Orange is currently working with manufacturers on the development of devices to be sold later in the year.

HD Voice uses the WB-AMR (Wideband Adaptive Multi-Rate) speech codec, which provides better quality audio due to a wider speech bandwidth of 50 – 7000 Hz compared to the current narrowband speech codec of 300 – 3400 Hz.

Orange UK  chief executive Tom Alexander said: “Orange is proud to be leading the industry into the next decade by announcing a new standard in voice innovation that will transform the mobile experience for customers in the UK. 

“HD Voice really does inject a level of innovation into mobile phone calls, making it sound as if callers are actually in the same room.  Once people have tried it, they won’t want to go back.”
