HD voice goes live on Orange

Mobile phone network Orange has unveiled its high definition voice service on a number of handsets, which brings in a better quality of calls over the airwaves.

Orange is the first UK network to announce this service, which effectively reduces background noise and therefore improves the overall quality of a call. The Sony Ericsson Elm ‘Eco' handset arrives with a similar feature, but its technology is built in to the phone and it's not an over the air service.

This new feature from Orange is available on a number of handsets, such as the Nokia 5320, Nokia E5 and Samsung Omnia Pro. Other upcoming mobile phones will support the service too, where new devices will be shipped with an Orange HD Voice logo to identify the handset is compatible.

HD Voice runs from a 3G network and uses the WB-AMR (Wideband Adaptive Multi-Rate) speech codec, which provides better audio quality due to its wider speech bandwidth of 50-7000 Hz - as compared to the current narrowband speech codec of 300-3400 Hz.

Orange has been successfully trialling out HD voice since June, where we first brought you news of the technology at the end of 2009.

The service is available now and at no extra cost to 3G based Orange customers, where we suspect more handsets will support this ability within the next few months.
