HTC EVO 4G LTE Getting HD Voice Support Later This Year Adam Mills08/07/2012 HD voice support, one of the main features that Sprint introduced with the HTC EVO 4G LTE, will become available for the smartphone sometime later this year. Sprint confirmed the news to PhoneScoop, saying that it plans to launch HD voice support for the HTC EVO 4G LTE before the year’s end.Advertisement The carrier doesn’t expect HD voice support to take a more prominent role until 2013 when it will spread to more devices in Sprint’s lineup. The HTC EVO 4G LTE will get even better later this year. HD voice support is exactly what it sounds like it would be. Calls made using the service are immensely better sounding then those that are made without HD voice support.Advertisement That’s not to say that calls made on the HTC EVO 4G LTE at this time are bad. In fact, they are as good as any other phone. However, HD voice support will make people on the other end sound even more crisp then they already are.Advertisement This feature of course was one that Sprint introduced earlier this year alongside the HTC EVO 4G LTE itself. In fact, it was one of the features that Sprint touted at the EVO 4G LTE’s unveiling. And for good reason. We aren’t sure whether support will be coming to any other Sprint phones currently on the market – Samsung Galaxy S III, Samsung Galaxy Nexus – but we imagine that high-end phones of the future will all feature support for the service. No specific release date was given for the service so owners of the EVO 4G LTE should temper their expectations and assume that we are a ways off from an official release date.Advertisement After launching in mid-July, Sprint 4G LTE has become available in 15 cities across the United States. Sprint currently has plans to expand its network in September and the service has gone up early in some SF Bay Area cities. Those who tout Sprint 4G LTE devices in these areas are able to pull down 4G LTE data speeds that can reach 10 times faster than those on a normal 3G network.
