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.
48% match is inconclusive, what is the match to Trayvon?
That you could come to this conclusion is astounding; that you could use the phrase "scientific certainty" in the same statement is incredibly astounding.
