HD Voice Makes Cellphone Calls Sound Near-Perfect

The video above was produced by Martin Stanford from Sky News in the UK, and it shows you the dramatic difference between the usual sound of a cellphone call compared with HD Voice technology.

HD Voice is only offered so far on a few cellphones (and only on Orange in the UK), and it doesn’t work quite like other cellphone calls, using 3G to transmit and receive signals. In addition, both phones must be using the HD Voice service to enjoy this kind of sound quality.

The service works Adaptive Multi Rate Wideband (AMR-WB), tech that’s been around more than a decade. If the provider has a newer 3G network, according to VoIP Universal, all that’s required to update coverage is a software patch.

However, there’s not much incentive to change over to the HD Voice standard, because those users who paid extra for it might be disappointed because of the limited number of people they be able to talk to with HD audio.
