We are in the midst of an era where communication and people connection is driving change and the way business is performed. There is significant growth in data driven technologies and this was possible by an increase in infrastructure and network technology supporting wider bandwidth.

HD Voice has been the next step in voice clarity and quality in telephony systems which has contributed to better end user experience.
HD VOICE
High Definition Voice, also known as Wideband Audio refers to the next generation audio for telephony systems. This has improved voice quality as compared to the traditional digital telephone. It uses standard codecs such as G.722 and G.722.2 to accurately reproduce end user voice in the natural setting by covering a wide range of frequencies. The traditional narrowband services have a frequency range of 300HZ to 3400HZ whereas HD offers a range of 50HZ to 7000HZ. The image presented below illustrates the HD Voice frequency range.
HD voice enhances acoustical elements on phones, reduces noise and other variations and enriches voice quality. Distinguishing syllables such as “s, f, c, e, d” is much easier on HD voice. Operators of voice based services can differentiate their services on both mobile and fixed terminal networks such as GSM, UMTS, LTE, CDMA 2000, etc. Further, the operators can use the standard industry logo to capture more audience for their services.
