Orange UK has announced that it had started trialing a high-definition (HD) mobile voice service in Reading, Southampton and Bristol.
The new "Orange HD Voice" service will improve voice quality of calls by putting an end to distorted calls. It will offer greatly enhanced sound quality with same network resources by making use of Wideband Adaptive Multi-Rate speech codec. But, the new service will be offered at no extra cost.
A wider speed bandwidth of 50-700 Hz will be used in HD Voice calls to offer enhanced sound quality as compared with current narrowband speech code of 300- 3400 Hz.
To begin with, the new service will be made available on a few of the 3G enabled handsets; however it will be extended to a range of handsets compatible to offer HD Voice service.
Orange has plans to extend the new HD Voice service nationwide by the end of summer.
