Orange UK Launch HD Voice – A Great Improvement

Orange UK recently launched HD voice, which will give users much better audio quality during voice calls, I must admit I didn’t really think this was necesary at first, however the improvements are great.

If you scroll down you can see a video showing standard voice vs HD voice, it is a similar jump in quality as CD vs cassettes. I beleive that all carriers will soon begin offering a HD voice service.

At the moment there are only a handful of Orange handsets that support HD Voice, these are the Nokia E5, X6, 5230 and the Samsung Omnia Pro, however I am sure future devices will support HD voice as standard.

To give you a rough idea of how vast the improvement really is a standard phone call transmits audio at 6.6 kbps with frequency range of 300 to 3400 Hz, whereas a HD voice call transits audio at up to 23.85 kbps and a frequency range of 50 to 7000 Hz.

It is thought that this improvement will cause a lot more stress on Orange’s 3G network, let’s just hope Orange’s network is ready.

Do you feel the HD voice will become the standard in the future?

    What planet Are you from ? Want voice quality try skype on an iPhone, it’s really quite exceptional. As for knocking an iPhone, I drive a taxi, I use mine as a satnav, radio, credit card machine, phone, browser and just about anything. Got a nokia with tomtom have you ?

    You clearly aren’t very well informed.

    Isn't it funny how Engadget has chosen an iPhone vs Nokia to compare voice call quality.

    Obviously you can tell the difference between the 2 calls, however, I think it has to do more with the the sort of radios that both Apple and Nokia use for their handsets, than HD Voice by Orange.

    Let's not forget here that Nokia has been making phones for over 20 years. And if its one thing they know how to do best, is phones which provide outstanding call quality and signal reception. Their emphasis is always function before design, unlike Apple's iPhone which is clearly the opposite, i.e. iPhone 4.

    The iPhone is more of a gadget than an actual phone. Its phone capabilities are really quite poor (iPhone 4 anyone). The majority of people who own it will tell you so.
