You’re on a conference call. You might be taking notes or leading the conversation. Either way, one factor is more important than the rest: being able to hear who’s speaking on the other end. A clear line of communication is integral to successful business relationships, which is why businesses use HD voice to enhance audio quality for important meetings.
What is HD voice?
High-definition (HD) voice, also known as wideband audio, is a technology that improves the quality of calls. Traditional mobile conversations can be grainy because the frequency range is limited between 200 Hz and 3.4 kHz. However, HD voice extends further, offering 50 Hz – 7 kHz of audio, reducing background noise and allowing for depth of tone to create a smoother, clearer experience.
It works using wideband audio codecs that enable higher-quality phone calls without sacrificing internet stability, whether you’re on a 4G, 5G, or a broadband network.
- AMR-WB (Adaptive Multi-Rate Wideband): the most widely utilized for mobile networks
- G.722: popular for VoIP (Voice over Internet Protocol) and corporate communication systems
From a security perspective, it is important to note that while HD voice does use advanced codecs, it still relies on the network provider’s infrastructure and security protocols. That said, it can easily be secured by implementing encryption and other methods.
Why HD voice matters for communication
- Clearer conversations: Talk to each other naturally with an improved depth of tone and enhanced vocal clarity.
- Easier note-taking: Understandable communication means no more second-guessing whether your notes are correct.
- Ideal for remote workers: Keep business conversations flowing with out-of-office staff with maximum comprehension.
- More professional conference calls: Reduced distortion and background noise make for an overall increase in productivity and professionalism.
Using HD voice
If you’re using VoIP services, you probably already have HD voice. Platforms like Google Meets, Zoom, and Microsoft Teams work to reduce background noise and monitor your speech to make sure you’re not on mute when talking (which happens to the best of us).
And if you’re making calls using your phone, check if it supports HD voice. Modern smartphones (including iPhones and Androids) have a toggle option that can improve the quality of your calls.
HD voice is over ten years old but continues to make significant improvements in audio quality. As 5G networks spread, clarity in communication will improve thanks to their higher bandwidth. AI-powered voice processors are also on the rise and will further help to enhance speech clarity, noise cancellation, and even real-time translation.
