HD Voice (High Definition)

HD (High Definition) Voice is also know as Wide-band Audio. It extends the frequency range of sound travelling over a phone conversation, resulting in higher quality voice. The range of the human voice extends from 80 hertz to 14,000 hertz. Traditional, or narrow band telephone calls, limit audio frequencies to the range of 300 to 3400 hertz. HD Voice opens up that range to be between 30 hertz to 7000 hertz or higher.

This HD phone feature allows for phone conversations that are crystal clear and easily understood. You never have to worry about missing important pieces of information again. HD Voice makes your phone conversations more enjoyable and completely stress-free.

Listener benefits of wide-band audio (HDVoice) compared to traditional (narrow-band) are:

• Clearer overall sound quality.
• Easier to recognize voices, distinguish confusing sounds and understand accented speakers.
• Ease of deciphering words that have the sounds of ‘S’ or ‘F’ and ‘D’, ‘B’ or ‘P’ and others, often indistinguishable over standard telephone lines.
• Ability to hear faint talkers and to understand double-talk (when more than one person is speaking at the same time like in a conference call).
• More attention can be given to the call content and less brain function to try hearing what people are saying. This results in increased productivity and less fatigue on business calls.
• Better understanding in the face of other impairments, such as when talkers are using a speaker-phone or in the presence of background noise.

As you can see, HD Voice is an incredibly valuable feature to have on your phone. It ensures that you will never miss important information while on a phone call again, and it can keep stress levels down during important business calls.
