If you've been using a Sony Xperia T in the couple of weeks since its release, you may have already noticed this. Nevertheless, Sony Mobile has today confirmed on its official product blog that its new high-end phone for Europe, the Xperia T, supports the HD Voice standard for higher-quality voice calls over the mobile network. The feature is fully functional on the Xperia T, but it's not currently mentioned anywhere on the official Sony specification page.
To get the most out of HD Voice, both callers will need HD Voice supported handsets and mobile networks. In the UK, Three and EE (Orange + T-Mobile) currently support the standard. But with all the pieces in place, the difference in call quality can be quite striking, as we've noticed during our time with the Sony Xperia T.
As data use increases, there's a general trend away from traditional voice calls on mobile handsets. But if you still find yourself making lots of calls, it may be a feature worth looking for in your next smartphone.
