High-Definition Voice Initiative Launched in United Kingdom

XConnect, Polycom, BroadSoft and Dialogic are working together to promote the adoption of high-definition voice by service providers in the United Kingdom.

The initiative was launched in response to U.K. service providers’ interest in HD voice services. The HD initiative is designed to raise awareness and educate service providers about the benefits of HD voice and help them resolve implementation challenges.

As part of the initiative, XConnect announced that the XConnect Global HD Voice Federation is now open to HD voice-enabled service providers globally, following its successful launch in the United States.

First to join from the U.K. are service providers Simwood, SureVoIP and thevoicefactory.

The federation enables the exchange of HD voice calls among all participants, all interconnecting through XConnect’s carrier hub and routing through phone-number lookups via its carrier ENUM registry.

HD Voice Increases Call Duration, Says Skype

Jonathan Rosenberg, Skype chief technology strategist, says high-definition call quality can increase the length of a voice call 45 percent. That, in turn, could theoretically lead to higher revenues for application or service providers whose services are sold "by the minute." Call duration might have no revenue implications at all if the endpoints are talking on a "no incremental cost" basis, though.

Skype's studies suggest, as you would expect, that audio quality is higher on a high-definition call. The Skype survey suggests there is a correlation between call audio quality and call duration.

With the lowest quality, approximating mobile call quality, the average call lasted about 21.5 minutes. At the highest quality it went about 31 minutes.

It's difficult to say whether the relationship is correlational or causal, though. One variable might be that users on the highest-quality codecs are predisposed to use Skype for conferencing sessions, which would have call duration parameters quite different from a casual voice conversation between two people, for example.

Consumer Feedback on Smartphone AI Isn't That Helpful

It is a truism that consumers cannot envision what they never have seen, so perhaps it is not too surprising that artificial intelligence sm...
