Last year Orange released HD Voice and Three have just announced they we've rolled it out since May of this year. What you as a user should realise is that you'll need to do minimal work to experience this feature. As HD voice is enabled on a network level and is only available on 3G networks, all you as a user will need is a compatible handset.
Technically HD Voice is just an updated codec (WB-AMR Wideband Adaptive Multi-Rate codec) which captures more data, which in turn is sound. I experienced a few HD calls way back in January 2010 where Three did a little demo to a few journalists and myself on some Sony Ericsson K series devices. The difference in quality of HD voice is very much like day and night.
HD Voice
- Background noise is significantly reduced.
- Speech is much clearer - this is advantageous for understanding similar sounding words and letters.
- Sound is transmitted at a higher rate - deep low booming voices have more base, whilst higher pitch voices are clearer.
- Calls are more intimate - it almost seems the person is right there in your ear speaking to you.
- Requires both caller and receiver to have HD voice compatible handsets.
- Doesn't cost anything extra
Compatible Handsets (as confirmed by Three)
- Nokia C7, E7, N8, X7
- LG Optimus 3D
Further handsets will be confirmed by Three, so keep a check on their blog for news about your handset.
As HD voice calls are still new to us they’re only available between people on the Three network, and both the caller and the receiver need to have an HD Voice equipped phone. We are also looking to roll out cross-operator calls in the future. As soon as we can let you know more on this, we will.
