What is HD Voice?

First tested in 2006, HD voice enables significantly enhanced audio quality on mobile devices calls. It doubles the audio bandwidth available using an industry specified speech codec called Wideband Adaptive Multirate Speech (WB-AMR) which extends audio bandwidth to 50-7000 Hz, compared with today’s narrowband frequency range of 300-3400 Hz. Higher bandwidth means a clear voice experience with increased naturalness, presence and comfort, better differentiation and intelligibility.

How HD voice works:

For HD voice to function, the caller and receiver both need HD voice enabled devices on HD voice enabled networks.

Availability:

According to the GSA (General Services Administration), as of November 16, 2010 the HD voice service is available on 10 networks across 9 countries including the UK and India. Nokia says that number should be increasing as HD voice is expected to be adopted as a mainstream technology in the mobile industry for future UMTS and LTE devices.
