The World Wide Web Consortium (W3C) plays an important role in the development of the Web by creating standards and protocols for universal use and interoperability. The W3C Voice Browser working group is developing revolutionary markup languages similar to HTML that, instead of focusing on a visual interface, will cover "dialog, speech synthesis, speech recognition, call control and other aspects of interactive voice response applications." New specifications, such as VoiceXML and Call Control XML, are thoroughly covered on the group's site. Updates and news items about the work are posted often. With so much information, the site is somewhat cluttered, but is still relatively easy to navigate.
