Orange UK to launch mobile High Definition (HD) Voice in 2010

Orange has revealed it will be launching HD Voice nationwide for customers on its mobile network in 2010 - the first such announcement by a UK operator, and testament to the company’s focus on innovation. With its crystal clear, superior sound quality, Orange’s introduction of HD Voice will herald a new era for mobile communications and a new standard for the telecoms industry. HD Voice delivers excellent audio quality to mobile calls and will be available to Orange customers with a HD Voice enabled handset. Orange is already working with leading handset manufacturers on the development of devices to be rolled out next year.

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.”

HD Voice uses the WB-AMR (Wideband Adaptive Multi-Rate) speech codec. This provides excellent audio quality due to a wider speech bandwidth of 50–7000 Hz compared to the current narrowband speech codec of 300–3400 Hz. The WB-AMR (Wideband Adaptive Multi-Rate) delivers significantly enhanced sound quality whilst utilising the same network resources.

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