The Globe and Mail has an interesting tale of a Colombian drug lord who constantly had his facial features altered by plastic surgery to avoid capture. In the end he was undone by his voice! the US Drug Enforcement Agency (DEA) aided Brazilian authorities in tracking down Juan Carlos Ramirez Abadia through the use of voice recognition software. “The way you use your voice is as individual as fingerprints,” said Jim Hunter, a partner in Sao Paulo security company. “If they have a sample of a known voice and they get an unknown sample of sufficient length, they then test the unknown against the known.”
