Orange says the new voice technology, which is set to land in the UK in 2009, means customers will soon be able to enjoy clear voice calls without any interference from ambient sound. The operator says that High Definition Voice doubles the network spectrum devoted to the mobile voice so users will be able to whisper messages and still be heard clearly.
The service, which employs the Adaptive Multi Rate-Wideband (AMR-WB) codec, will be available on a range of devices and networks from 2009 in the UK.
Orange announced High Definition Voice technology at its La Collections show in Paris, where it also unveiled a new customisable Orange user interface, soon appear on a large selection of its top handsets.
Orange says that key devices will feature a set of pre-installed applications designed to offer fast access to TV, music, photos, widgets, web browsing, secure back-up and email.
Users will have the option of using a phone's proprietary UI or the new Orange user interface. It means that Orange users will be able to change phones without the hassle of learning a new UI. The service is already available in France.
