Profiting from crystal-clear voice calls
What is HD voice?
HD voice stands for high definition voice. Using wideband technology and further acoustical enhancement on telephones, it provides consumers with high-quality, crystal-clear and more natural voice calls, on both mobile and fixed terminal networks.
Who is HD voice relevant for?
- Network vendors; and
What are the benefits of HD voice?
- Enjoy greater clarity; and
- Experience intelligently reduced background noise.
Operators and network vendors:
- Deliver enriched voice communications;
- Differentiate their services;
- Gain competitive advantage over industry players who don’t yet offer HD voice; and
- Monetise the opportunity by encouraging callers to speak for longer and more often.
What is the GSMA doing to help in relation to HD voice?
We’re a strong promoter of the consumer benefits of this technology. That’s why we’re working hard to ensure it is used as extensively as possible. In collaboration with the telecommunications industry as a whole, we’re also supporting the adoption of a universal HD voice symbol.
The HD voice symbol
The logo gives consumers confidence that a defined quality of experience is ensured when making an end-to-end HD voice call. The symbol is becoming more widely recognised. Use of this logo lets organisations clearly identify and promote HD voice-enabled devices and services to a global audience. There is also no charge to use the logo.
The GSMA and the HD voice logo
We are the custodian of the logo on behalf of the industry and the contact for licensee applications. We define technical mobile network and terminal requirements for logo usage on:
- LTE; and
- CDMA2000 technology.
In addition, the GSMA has collaborated with the DECT Forum to provide terminal requirements for DECT handsets.
