Orange to provide HD voice calls in the UK V.J. | , 2:48 p.m. Jan. 4, 2010 2010-01-04

The upcoming service will deliver high-definition voice calls which basically means impeccable audio quality. The service will become available to Orange subscribers over the course of 2010.

The new HD Voice service will bring excellent audio quality to mobile calls using the WB-AMR (Wideband Adaptive Multi-Rate) speech codec. The codec enhances audio quality due to a wider speech bandwidth of 5-7,000 Hz. Compared to the current band speech codec of 300-3,400 Hz, the voice quality will definitely be improved.

The WB-AMR codec does not require additional network resources, informs Softpedia. In consequence, the costs for making this work will be minimal.

“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,” said Tom Alexander, CEO of Orange UK.

Orange did not, however, offered any details on what types of mobile phones will support the HD Voice service.
