The Financial Times (FT) caught Skype CTO Jonathan Rosenberg at eComm yesterday touting the virtues of HD voice and the SILK superwideband codec and noted the HD Voice Summit at 2010 CES.
Rosenberg presented data showing that users talk almost 50 percent longer when using HD voice as compared to G.729. He also underlined what HD voice advocates having been saying for a while – higher quality means more engagement.
In his presentation, Rosenberg suggested that more HD voice minutes could translate to more money for operators, then turned around and noted that Skype had served more than 36 billion minutes of Skype-to-Skype (i.e. revenue not going into the pockets of operators) minutes during the fourth quarter of 2009, up from 20 billion minutes a year ago.
FT said the HD voice movement “is getting louder and clearer” with the HD Voice Summit at this year’s Consumer Electronics Show and “is set to grow in tandem” with high quality video calls.
