The authenticity of a new audio tape purportedly made by bin Laden, in which he praises recent attacks in Bali, Kuwait, Yemen and Moscow (see November 12, 2002), is disputed by Swiss voice analysts. US officials believe the voice is “almost certainly” bin Laden, but the Dalle Molle Institute for Perceptual Artificial Intelligence in Switzerland, one of the world’s leading voice-recognition institutes, is 95 percent certain the tape is a forgery. [BBC, 11/13/2002; BBC, 11/18/2002; BBC, 11/29/2002; Toronto Star, 12/16/2002] Two weeks after it was broadcast, a British newspaper publishes the complete text of a “letter to the American people,” purportedly written by bin Laden. [Observer, 11/25/2002] However, “diplomats [are] skeptical about the authenticity of the document.” [Guardian, 10/15/2002] The institute will not continue to analyse bin Laden’s speeches (see February 12, 2003).
