One of the biggest challenges the telecommunications sector has had to deal with was reproducing the human voice. Since the dawn of telephony in the 1870s, it has been a goal of technology leaders to capture the full breadth of the human voice’s quality. Today, they are closer to this goal than ever before, thanks to the availability of wideband audio technology, which is presently used in high-definition (HD) voice telephone systems.
The broadcasting industry pioneered the use of an early form of wideband audio codec known as G.772. Thanks to its use of a wider speech bandwidth (50 to 7,000 Hz) compared to typical narrowband codecs (200-3,400 Hz), the resulting voice quality was greatly improved.
Approved by the International Telecommunication Union’s Telecommunication Standardization Sector in 1988, G.772 became very useful for networks who wanted to carry out high-quality broadcasts from far-off locations.
With the plethora of communications and recording devices available in the market today, it is tempting to think that capturing the human voice is pretty much a straightforward task. True enough, recording human voices or transmitting them over phone calls is pretty simple. However, making them sound rich, defined, and natural is a different thing altogether.
HD voice systems try to achieve this objective by employing wideband audio technology to capture the complexity of the human voice, particularly its different octaves. Traditional narrowband phones can capture only between 300 Hz to 3.4 Hz of the sound spectrum of human voice, which can range between 80 Hz to 14 kHz. Because communication devices with HD voice technology can capture an audio frequency range of between 50 Hz to 7 kHz or higher, it is more in step with the human voice, resulting in a sound that is less robotic and fragmented.
Clearly, the greatest advantage you can gain from obtaining telecommunication devices that use wideband audio technology is better communication. Because HD voice systems transmit and receive a wider range of human voice frequency, they certainly provide richer, more natural-sounding, and more lifelike voices during calls.
Furthermore, HD voice technology can also actively detect and minimize noise from the surroundings, making your voice more definite and more easily understood by the person with whom you are speaking.
This elevated calling experience is especially beneficial for business owners, who want their phone calls to be crystal clear for better and more accurate communications with their clients, colleagues, partners, and other stakeholders.
