On the George Zimmerman/Trayvon Martin case:

“There’s a huge chance that this is not Zimmerman’s voice,” said Primeau, a longtime audio engineer who is listed as an expert in recorded evidence by the American College of Forensic Examiners International. “As a matter of fact, after 28 years of doing this, I would put my reputation on the line and say this is not George Zimmerman screaming.”

Owen, a forensic audio analyst who is also chairman emeritus of the American Board of Recorded Evidence, also said that he does not believe the screams come from Zimmerman.

Software frequently used to analyze voices in legal cases shows a 48% likelihood that the voice is Zimmerman’s. At least 60% is necessary to feel confident that two samples are from the same source, he said Monday on CNN. That means it’s unlikely the screams came from Zimmerman, Owen said.
