The single most powerful element that binds people together is the comforting sound of a familiar voice. Nothing can signify trust and emotions better than having a face to face conversation with a family member or a friend. The telephone tried for so many years to approximate the quality and depth of a human voice but the limitations of the technology have not made this a possibility.

Advances in VoIP systems however have made several enhancements to the quality and delivery of high definition voice signals through wideband technologies. The result is better audio quality and a deeper clarity of voice that approximates that of the human voice, making HD VoIP calls superior to those that take place over the traditional PSTN or Public Switched Telephone Networks.

Cost was the foremost reason why businesses and home networks have switched over to VoIP telephony, but the emergence of high definition features makes VoIP even more attractive to users. As advances in this technology continue to overcome hurdles to fully implementing high definition VoIP for home telephony use, it will only be a matter of time before HD VoIP changes the face of home telephony.

What is HD Voice and What Can it do for VoIP Telephony

Listening to HD voice is likened by some experts to listening to high quality CD sound for the first time after years of listening to AM Radio. However, to fully understand what HD VoIP is, users must first have a clear understanding of the principles behind VoIP technologies in general. This can be simplified by comparing the range of frequencies telephony technologies operate on as compared to the human voice.

Human speech span frequencies between 30 to 13000 Hz and the recipient should hear most of these frequencies in order to fully capture the depth, intonation and quality of sound of the speaker’s voice. Standard PSTN networks operate in frequency ranges between 300 to 3300 Hz and are only a fraction of what the human speech can contain. Frequencies beyond the range of the PSTN phone are simply clipped off resulting in poor sounds. To better understand this, try listening to the sound of an AM radio broadcast – PSTN frequencies are much narrower than that.

HD voice on the other hand has a range that covers frequencies between 40 to 7000 Hz, resulting in transmission qualities that are near the depth of a natural human voice. Voice sampling rates for HD is at 16,000 times per second which is double that of PSTN phones with sampling rates of 8,000 times per second. It does not capture the full range of frequencies of the natural voice but its wideband range can deliver enough voice quality to make HD VoIP phone calls sound like an ordinary face to face conversation.

The Advantages of VoIP with HD Voice for Your Home

Both business and household users want high quality communication channels to enhance and simplify their lives. However, not everyone has access to a fully convergent home communication system where they can call, send messages or have video conversations from any telecommunications device available in the home.

With HD VoIP systems, consumers from the home can enjoy twice the clarity and quality of voice than ordinary telephone calls. Family members and friends can enjoy vibrant and lifelike conversations from across long distances or even across the world as if they are in the room together with you. Such experiences can eliminate certain problems inherent in traditional phone lines such as mistaking the sound cialis cheap of “s” with “f”. The result is clearer and more effective communications – conversations between friends or family members as they should be.
