Sprint Reveals Details of HD Voice Service

May 9, 2012, 4:41 PM by Rich Brome @richbrome

At CTIA this week, Sprint and Qualcomm revealed new details of Sprint's forthcoming HD Voice service. Sprint says they won't charge for the feature; it will automatically be used for all voice calls whenever the network and both phones support it. According to Qualcomm employees involved in the project, Sprint is also requiring that all phones marketed as supporting HD Voice include active background noise cancelation using two microphones. The HTC EVO 4G LTE is the first US phone to support HD Voice. The feature will initially be disabled in software, but can easily be enabled by Sprint once the network is ready. Network support for HD Voice will be deployed as part of Sprint's Network Vision upgrades throughout 2012, which also include LTE 1900, CDMA 800, and CDMA 1x Advanced. For the near future, it will only work between two Sprint HD Voice phones, and only on parts of the network that support CDMA 1x Advanced.

another reason Sprint will reign supreme

I work for an outsourcing company that supply's Care and Tech support for Sprint... I have to say after being in this division for over 6 years and seeing where we were, when we went down and now our climb back up it's a different world all around for sprint...

I'm glad to say that I've been part of the good, the bad and the now soon to become awesome!!!

There's so many good things Sprint has in works and I can't wait for Network Vision to take full Force and the phones on LTE to be released so that EVERYONE including AT&T, Verizon and T-Mobile can see what Sprint can truly do...

Oh, and I tried it today. It does, indeed, sound really great! 🙂 (Eric tried it out at the EVO 4G launch event, but this was my first time using it.)

You can finally hear a pin drop on your Sprint phone. 😉

Hey Rich, hope you've been well. So isn't this just really a voice codec change/channel allotment difference? Maybe the equivalent of GSM's EFR codec?

So you tried it between two Sprint phones that could support it? As the article says? Or was it just a call made from a Sprint HD phone to some other non HD phone?

Might you know what Vzn's timeline is for VoLTE?
And if there is any chance the GSIII might support
VoLTE?
