What do you get when you cross the daily news with Half-Life 2? You get News at Seven with Alyx Vance. The system, developed at Northwestern University, automatically finds new news stories, auto-formats them, and uses text-to-speech technology to give Alyx her "voice."
In this, our first deployment of the system, the show produced is a three-minute daily news update, featuring national, international, and human-interest stories, with commentary from blogs on the national story. After the material has been assembled, the system is ready to present the news using preset scripts. The engine, and our extensions to it, allows us to present believable human-like newscasters as well as more imaginative scenes and sets that are only possible because the show is virtual. We also use techniques to make the generated vocal audio more interesting and believable.For more information, see the ABC News segment on the virtual show, and also a sample of News at Seven can be found here.
