Orange will become the first UK mobile operator to launch a high-definition service with the launch of HD Voice in 2010.

It says UK trials will be announced early this year, with full nationwide roll-out due later in 2010.

The company claims HD Voice will deliver excellent audio quality for mobile calls. The service will require customers to upgrade to an Orange HD Voice enabled handset, and Orange says it is already working with leading handset manufacturers on the development of devices to be rolled out in 2010.

‘HD Voice makes it sound as if callers are in the same room’

Tom Alexander, CEO of Orange UK, 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.’

Orange has also set out the technical details of the new HD Voice service. It is set to use the WB-AMR (Wideband Adaptive Multi-Rate) speech codec, which provides excellent audio quality due to a wider speech bandwidth of 50–7,000 Hz compared to the current narrowband speech codec of 300–3,400 Hz. 

Significantly, Orange says that HD Voice offers enhanced sound quality whilst utilising the same network resources.

Further details on the Orange HD Voice roll out will be made available later in 2010.
