Improving acoustic speaker verification with visual Body-Language features
Christoph Bregler, George Williams, Sally Rosenthal, Ian E. McDowall · 2009
We show how an SVM based acoustic speaker verification system can be significantly improved in incorporating new visual features that capture the speaker's ldquobody language.rdquo We apply this system to many hours of Internet videos and TV broadcasts of politicians and other public figures. Our data ranges from current and former US election candidates to the Queen of England, the President of France, and the Pope, while giving speeches.
