Orange has confirmed that the Samsung Omnia 7 will be HD Voice enabled in the UK, allowing the Windows Phone 7 handset to make higher quality audio calls on their network. "High Definition Voice" had previously been limited to a handful of Nokia devices, along with the Samsung Omnia Pro; calls between compatible phones promise much reduced background noise, hiss and crackle.
Orange is still hoping to get more networks - and device manufacturers - onboard with HD Voice, so that the technology will pick up steam and become more prevalent. Until then, only Orange customers - and not those roaming from T-Mobile, either - will be able to take advantage of it. Still, a strong handset might be what HD Voice needs to break through into the mainstream, and it certainly won't hurt Samsung in differentiating their hardware from other Windows Phone 7 manufacturers.
