After 17 year old Trayvon Martin was shot and killed by neighborhood watchman George Zimmerman, everyone has weighed in, including politicians, bloggers and the media. The 911 call which displays a man screaming for help is on everyone’s mind; whose voice is it?
The Orlando Sentinel had leading experts in the field of forensic voice identification answer that question. The experts after analysis deemed the voice to not be that of George Zimmerman, however, they did not have a recording of Trayvon’s voice to analyze.
Orlando Sentinel reports:
After the Sentinel contacted Owen, he used software called Easy Voice Biometrics to compare Zimmerman’s voice to the 911 call screams.
“I took all of the screams and put those together, and cut out everything else,” Owen says.
The software compared that audio to Zimmerman’s voice. It returned a 48 percent match. Owen said to reach a positive match with audio of this quality, he’d expect higher than 90 percent.
“As a result of that, you can say with reasonable scientific certainty that it’s not Zimmerman,” Owen says, stressing that he cannot confirm the voice as Trayvon’s, because he didn’t have a sample of the teen’s voice to compare.
Forensic voice identification is not a new or novel concept; in fact, a recent U.S. Department of Justice committee report notes that federal interest in the technology “has a history of nearly 70 years.”
There is a lot of speculation being tossed about — some recklessly, and some out of concern for justice – but with this story highlighted due to efforts by activists to push it into the public eye, the truth will come out.
