What is HD Voice?

Nokia  Conversations asks: What is HD Voice? This is basically new technology that improves the quality of a voice call -that really bad FM radio quality sound – though something we’ve just gotten used to. It’s like the AMR vs MP3/WAV (now MMS vs High) recording on a Nokia Nseries. The difference is clear, with the latter feeling like you’re back in that environment (though has a lot to do too with high grade Nseries recording equipment)

That’s where HD voice comes in.

“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. You know how the accent of your friend from Manchester is difficult to understand? Well HD voice won’t help with that. That Mancunian accident is impossible to comprehend (It’s almost as bad as my Baltimorian accent). But HD voice will create a feeling of being closer to the caller as the quality competes with Internet based HD voice services.”

HD Voice is available right now in 9 countries, UK included. But to have HD Voice, you’d need a HD Voice enabled handset (on both ends). When’s this technology coming to Nokia? Well they’ve already got it in 15 current devices and it will be included in many of 2011’s new handsets (e.g. E7, though technically that’s a 2010 handset:p).

This includes the Nokia X6, the budget X3-02/C3-01, E5, N8, C7, 5230 (not sure that 8 are, the NokConv article only listed 5, the other two were found on Orange’s site)

Orange has an advert below to kinda show you what HD voice is about, though you’ll want to check out Engadget’s E5 to E5 demo vs iPhone to E5 (Second video in this post)
