UK trial of Orange HD Voice starts this spring

Codec delivers better audio quality on mobile calls

Orange is to begin a trial of its HD voice service in the UK later this year.

"HD voice is the future standard for mobile communication and, by being the first to innovate and deliver a new mobile voice experience, we provide a compelling and differentiated proposition which sets Orange apart," said Olaf Swantee, senior executive vice president for global mobile business at Orange.

HD Voice uses the speech bandwidth of 50-7000Hz compared to the current narrowband speech codec of 300-3400 Hz, which, according to Orange, "delivers excellent audio quality to mobile calls".

Orange said the three-month trial will begin this spring.

The network has been working with handset manufacturers on creating devices that support the technology, and said pricing and compatible handsets will be announced when the trial begins.
