A group of Swiss researchers said today that an imposter almost certainly created the recent audio tape attributed to terrorist leader Osama bin Laden.
In a report aired on French television last night, the Lausanne-based Dalle Molle Institute for Perceptual Artificial Intelligence (IDIAP), said it was 95% certain the tape does not feature Bin Laden's voice. The review of the tape was commissioned by France-2 television. IDIAP's director, Herve Bourlard, said the institute compared the voice on the tape - first aired two weeks ago on Arabic television network Al-Jazeera - with some 20 earlier recordings attributed to bin Laden.
