Expert Voice Analysts say Zimmerman not person screaming for help on 911 call


The Orlando Sentinel contracted voice analysts to determine if Zimmerman’s voice could be reasonably expected to be the voice on the 911 call:

The Sentinel said it contacted Owen, who it described as a court-qualified expert witness and former chief engineer for the New York Public Library’s Rodgers and Hammerstein Archives of Recorded Sound. He told the newspaper he used software called Easy Voice Biometrics to compare Zimmerman’s voice to the 911 call screams.

Owen told the newspaper that the software compared the screams to Zimmerman’s voice and returned a 48 percent match. He said he would expect a match of higher than 90 percent, considering the quality of the audio.

“As a result of that, you can say with reasonable scientific certainty that it’s not Zimmerman,” Owen told the Sentinel.

But he also said he could not confirm the voice as Trayvon’s, because he didn’t have a sample of the teen’s voice.

The Sentinel said that Ed Primeau, a Michigan-based audio engineer and forensics expert, used audio enhancement and human analysis and came to the same conclusion.
