HD Voice is a 4G LTE audio technology offered by some mobile service providers. It reduces background noise and improves the sound quality of your calls. Here's a closer look at HD Voice and how it works.
What exactly is HD Voice and how does it work?
HD Voice is high-definition voice calling. It is a wideband audio technology that provides a superior standard for conversations. By extending the frequency range of audio signals, HD Voice does two things well:
With HD Voice, calls are clearer and sharper, providing a better experience for everyone on the call, whether you’re chatting with friends and family or teleconferencing with business associates at work.
HD Voice is powered by VoLTE (Voice over Long Term Evolution) technology. Many carriers use the two terms interchangeably. VoLTE is the next generation of VoIP, a technology that enables telephone services over the Internet. VoLTE is similar to VoIP, except that it uses a carrier’s LTE data network, not Wi-Fi, to send and receive calls.
