Forensic Experts: with ‘Scientific Certainty’ it was not Zimmerman’s voice screaming for help

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:

‘Scientific certainty’

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.

    The guy on the ground with the gun shoved in his back yells for help.If zimmy yelled “help”, it was to muffle the gunshot noise.

    • reyinam

      Are you trolling? Trayvon was on top of Zimm

      • Jajajagena

        He was obviously NOT on top of him when he got shot or Zimmerman would have had the kid’s blood all over his shirt and he did not, as seen so plainly in the surveillance tape at the police department.

        • STOP!

          how would any of you maroons know who was where… the only people who know what happened are Zimmerman and Martin. We only have one side of the story seeing as how Martin was killed. Everyone needs to stop making assumptions, especially the dumbass media causing a stir and forcing mob rule. Maybe Zimmerman IS innocent in this, but if we all demand his head, then there is no justice. This is the USA, not Ancient Rome, the people cannot accuse someone of murder and have him arrested. It doesn’t work like that. The law is INNOCENT UNTIL PROVEN GUILTY. So, please, calm the hell down and let the justice system do its job.

          • Argle McBargle

            I think it was because the justice system was rather obviously not doing its job that people got upset in the first place. The issue for me is not whether Zimmerman is guilty or innocent – I don’t know which is true, and neither does anyone else. The issue for me is that the justice system in this case seemed very willing to simply let a matter involving someone’s violent death simply drop after a very cursory investigation.

        • Moredots

          Nah, wouldn’t necessarily have blood on his shirt if he pushed the kid off after the shot.
          I’m kind of an expert because I have shot tons of people who were on top of me, and never gotten their blood on my shirt.

          A bit ignorant there, Martin was 17 and played football; I guess the definition of kid can have a bit of leeway though.
          Also, you’re adding ~50 lbs onto Zim, based off basically all reports.

          beg to differ ethan. The real facts are that 250lb photo is a pic of zimmerman from 2005. Zimmerman wieghs close to 160 in 2012 look at the police station video again. Traydon pic was at 13. At 17 he is 6ft 3in. Taller than zimmerman. Plays football..He would know how to tackle.

          • Jik29

            The police station video shows a man that is definitely larger than 160 lbs. And here are some other recent pictures of Trayvon (including recent Prom picture) –he was not a very buff football player but see for yourself.

    Both of those pictures are photoshopped. The picture of Trayvon does not display the correct face for that picture and the picture of Zimmerman has been lightened to show him as white, he is actually Latino/White mix.

      You absolutely make no logical sense. “The picture of Trayvon does not display the correct face”<— that is absolutely his face, taken from his Facebook account. I know sometimes facts do not conform to your simplistic world view but that doesn't give you the ability to start changing facts. And again, Hispanic refers to a culture, white/black/mulatto/mixed refers to a race. So not only has that picture not been edited to show him "lightened" as you say, but you can be a white Latino without being a "mix".

        How is it ignorant? Think about it: Who has benefited the most from the “forensic sciences?” I think it’s rather suspicious that far more black men have been freed from death row thanks to DNA “evidence” than have white men. When was the last time you heard about a white guy being exonerated due to DNA evidence? When was the last time we discovered a white guy was “wrongfully accused” thanks to DNA? Probably not ever.

        Science seems to agree that DNA is not sufficient evidence to “prove” the theory of evolution. Yet, it is sufficient to prove the innocence of criminals? This doesn’t make any sense.

        The people who are most frequently exonerated by forensic evidence are the same group of people who commit the most crimes. No coincidence here.

    The race pimps have such a hard on for this guy to be full on white they cant stand it.

Think Obama should be referred to as the White African American if we’re doing this White Hispanic stuff now.

      I am sorry if the difference between race and ethnicity has been overwhelming for your shielded brain. As you mentioned, the news has always annoyed the hell out of me when people look out for two “Hispanic” men. The ethnicity Hispanic has been recently conflated as a racial description by xenophobes and people who do not have the brain power to handle complexity (basically people who see things in black and white terms only, no pun intended). Simply put, all Hispanic means is “of or relating to Spain or to Spanish-speaking countries”. Can you at least grasp the idea that a country that is Hispanic has their own form of racial diversity where there are mulattos, blacks, whites, asians…

    Owen said it’s a 48% match, and he would expect that to be higher in recordings of this poor quality, but also didn’t compare the recordings they have of Trayvon Martin (from his phone, other recorded messages that are available from him, etc.)

    -Taken from reddit poster “justanothercommenter”

    “As a result of that, you can say with reasonable scientific certainty that it’s not Zimmerman.” You could also say with reasonable scientific certainty that it might be Zimmerman (since it’s a 48% match).

    Now, let’s get to Mr. Owen. Is he really a “forensics expert?”

    Well, no. He has a B.A. in History, not forensics.

    Well, surely since he’s an expert, he went to Harvard or Yale or Oxford, right?

    Well, no he went to Bellarmine College in Kentucky. You’ve heard of Bellarmine College, right?

    Well, but surely he’s worked for the FBI or CIA as a forensics examiner?

    No, but he did work for the New York Public Library in charge of their Rogers and Hammerstein archive – coughgaycough.

    But surely he’s written some books about forensics that the FBI and CIA use, right?

    No, but he has written extensively about the banjo and did a coloring book:

    Tom Owen, Scaling the Fretboard (Chappell Music 1973)
    Tom Owen, The Chord Coloring Book (Chappell Music 1974)
    Tom Owen, Tenor Banjo (Chappell Music 1975)
    Tom Owen, Lead Guitar (Chappell Music 1976)
    Tom Owen, The Classic Blues Singers (Chappell Music 1977)

    What about his wife Jennifer Owen … surely she’s a hotshot FBI forensics examiner, right?

    No, she makes Powerpoint presentations and is a secretary with a political science degree, not a forensics degree.

    On the plus side, she lists a February 2003 course in Microsoft Office on her CV. So if you need her to type up your bullshit story for you, she’s your goto.

    But surely they have an advanced forensic acoustics labratory where they conduct their forensic analysis right?

    No, they just have a computer in the basement of their house in New Jersey right next to the railroad tracks.

    But surely he’s a member of the American Board of Recorded Evidence.

    Yes, he and his wife run the outfit. He’s the chairman, and she’s a board member. The Board is run out of a weight-loss clinic in Springfield, Missouri. They certified themselves experts by creating this fake board.

    They do tend to testify in a lot of cases if you pay their fees and travel expenses, though.

    Now, let’s examine the software they used to perform their analysis. How good is it?

    Well, given two KNOWN samples of speech by President Richard M. Nixon, the software only matched two recordings to a 86% match.

    Remember, Mr. Owen said he’d expect a 90% match before he concluded that the voices were identical. But in the software makers own demonstration of the product, using two KNOWN samples of speech from the same famous person, there was only an 86% match.

    What about the algorithm they’re using to make the comparison? How good is it? UNKNOWN. That’s propietary. They won’t tell you what they’re actually measuring.

    What about the second “expert,” Ed Primeau. Surely he was educated in forensics?

    Nope. He was a Communication Major, like Katie Couric. Only he didn’t graduate and was awarded no degree. He was a probation officer.

    Here’s what he said: “I believe that’s Trayvon Martin in the background, without a doubt,” Primeau says, stressing that the tone of the voice is a giveaway. “That’s a young man screaming.”

    And remember, there’s allegedly NO AUDIO TO COMPARE OF TRAYVON’s VOICE. But somehow, the second expert was able to match it even without any way to compare what he heard to a known recording of Trayvon Martin.

    • shivabeach

      There was no need to compare to Trayvons voice because Zimmerman made the claim it was him crying for help. The 90% match would conclusively mean that it WAS Zimmermans voice based on the tapes.

      However, the test only came back 46% which indicates it it most certainly NOT a match for Zimmerman

      Which leaves….who? Take all the time you want.

      Did you read the part in other articles where this test has been being used for a very long time?

    Mr. Owen. Is NOT really a “forensics expert?” He has a B.A. in History, not forensics. He has never worked FBI or CIA as a forensics examiner? But he did work for the New York Public Library in charge of their Rogers and Hammerstein archive. He doesn’t have a lab he has a computer in the basement of their house in New Jersey right next to the railroad tracks. That American Board of Recorded Evidence he a member of. LOL he and his wife run that. Mr Owen doesn’t seem to understand basic statistical inference. This is an example of how easy it is to mislead the layman with statistical arguments. Given that a 90 percent match is supposedly needed to prove that a voice sample matches an individual, and that only a 48 percent match was found for Zimmerman, all we can say is “the software was unable to prove that Zimmerman’s voice is on the recording.” Note that this statement is profoundly different from “the software proved that Zimmerman’s voice was not on the recording.” This is a very basic Stats 101 error that is made all the time by people with no statistical training,

  • the616kid

    This doesn’t paint a picture. I am on neither side, because this sudden race war is retarded, (yeah, fuck you spike lee) and all I want is facts. The only thing this proves is that it was not Zimmerman screaming. The only people that know what happened is Zimmerman and the late Trayvon. Zimmerman was definitely in the wrong though by stalking him like some rent-a-cop hero, and not letting the police do their job if he had a real reason to be concerned.

  • Peoplearestupid

    So you do agree then that there should be a trial and that Zimmerman should not have been let go as easily as the Sanford police department let him go? That is where the racism is in this case–the fact that a dead black kid did not warrant a proper investigation. It is sad that the media has to shout and scream about it for this case to get a proper investigation, like it originally should have.

  • Yestheyare

    I agree that there should be a trial but I completely disagree with your assertion that Zimmerman should not have been let go.

    You are apparently one of the stupid people if you think that potentially innocent people should be held in jail for months BEFORE their trial.

    Lets let the system do its job. There will be a trial of some type…be it murder or manslaughter or whatever and THAT is where all the facts of this case will come out.

    He wasn’t “stalking” him. He was following him in order to let the police know which way Martin was heading. When the operator asked if he was following him, to which Zimmerman replied with a yes, the operator told him to stop…. and he stopped, turned around, and headed back to the clubhouse to meet up with the police. I take it you are only getting your info from a completely biased source.

    Wrong. He continued to follow martin. Zimmerman never left Martin once he confronted him. It was only 5 minutes between the time Zimmerman confronted him and the cops showed up AT THE ScENE. Not at the clubhouse. Zimmerman was there waiting with a dead body. Lie all you want, but the evidence is making a fool of you
