Exclusive: Jio releases video demo of HD voice calling on VoLTE platform

Reliance Jio which is expected to go for a commercial launch of services by April 2016 has released a video demonstrating how HD voice calling is a generation ahead of analogue GSM voice calls. VoLTE is a technology whereby voice is treated as just another service being carried on the LTE data network much like the widely used VoIP technology used today in apps like whatsapp and skype but without the need of a 3rd party app with the native phone operating system supporting the voice calling over LTE.

As you can hear in the voice samples demonstrated in the video, GSM voice is of inferior quality with a lot of background interference while HD voice call sounds crystal clear without any disturbance. VoLTE and VoWiFi will be supported on all LYF branded phones and VoLTE will also function on other compatible handsets which support HD voice feature.

HD Voice is essentially wideband audio technology, something that long has been used for conference calling and VoIP apps. Instead of limiting a call frequency to between 300 Hz and 3.4 kHz, a wideband audio call transmits at a range of 50 Hz to 7 kHz, or higher. That’s much more in line with the human voice, which transmits audio between 75 Hz and 14 kHz.

HD Voice also takes in more audio samples per second than a standard call. Instead of 8,000 audio samples per second, HD Voice calls double that to 16,000. That way, you’re able to hear more details in a person’s voice during a call.

It’s a marketing gimmick obviously.. HD Voice can be implemented in 2G and 3G GSM too..Like, take an example of airtel’s platinum 3G in Mumbai, to experience best voice all you need is a phone supporting dual band 3G, having active noise cancellation with dedicated mic with HD Voice enabled on it by default.. They should have shown advantage of HD Voice in LTE over HD Voice in 3G instead, to lure me atleast.. First call sounds like that it was made from basic 2G GSM phone with user replaceable battery and memory card slot… Background noise can be suppressed… Read more »
