Voice forensics experts cast doubt on Sentinel analysis of Trayvon Martin 911 tape
http://dailycaller.com/2012/04/06/voice-forensics-experts-cast-doubt-on-orlando-sentinel-analysis-of-trayvon-martin-911-tape/ ^

Voice recognition experts who spoke to The Daily Caller questioned the methodology and conclusions of a voice-identification analysis published by the Orlando Sentinel on March 31.

Using two different forensic methods, the Sentinel’s chosen authorities determined that a scream heard in the background of a widely aired 911 call was not that of George Zimmerman, the man who fatally shot 17-year-old Trayvon Martin on Feb. 26

How come I can fairly clear hear Zimmerman exit his truck INTO THE COLD RAINY WEATHER and then hear him say “sss F__kin’ cold”? Does this make too much sense for it to be a fact?

Obama and his democrat party ordered their media operatives to lynch Mr. Zimmerman and create racial discord. The attempted lynching took the form of gross faking of the evidence and extreme journalistic malpractice.

I think that the reason ABC, NBC, and the Sun-Sentinal (among many other operatives) are creating fake evidence, in that Obama support is surprisingly weak among blacks.

No one has suffered more in Obama’s Great Recession than the blacks: 50% youth unemployment, horrific democrat party big city Teachers Union education, etc.

Hence the need for a diversion.

That’s unpossiball!

A handful of idiot FReepers said the two
Martin camp hired sound experts prove Zimmerman is a racist killer who went out hunting little black bunnies that night and shot Trayvons in the chest using a .50 cal rifle and HEP ammo!

Whatever will they say regarding this latest news!?

My guess is not a damn thing.

-- did you actually read the article? Definitely anti-Zimmerman. --

It's got some of both. The last two paragraphs pertain to an expert who says Tom Owen's "the screaming isn't Zimmerman" conclusion is flawed. He uses language that is more harsh than mine.

Huh??

The article says that no voice analysis technique is accurate under these circumstances. That may not help Zimmerman’s case but it is equally damaging to the Orlando Sentinel’s experts who claim the screams were from Martin.

Dr. James Wayman, a San Jose State University expert in the field of speech science, told The Daily Caller that he questions the grounds on which Owen based his analysis.

Wayman also said he would be willing to testify against the admissibility of Owen’s findings on the grounds that they don’t meet the criteria required for evidence in federal courts.

“There is no history of, or data on, the comparison of a questioned scream to a known speech sample,” Wayman said.

The problem, he said, is that the two voice samples were recorded in difficult acoustic conditions over different cell phones.

“Even if we were to have Mr. Zimmerman recreate the scream under identical conditions with the same cell phone,” Wayman explained, “it would be difficult to attribute the scream to him without a sample of a similar scream from Mr. Martin under the same conditions. This is clearly not possible.”

"Definitely anti-Zimmerman."

While not pro-Zimmerman, it most certainly is NOT anti-Zimmerman. It is decidedly neutral, and throws the Slantinel's voice recognition stance in doubt.

I was flying on Monday morning, and I saw one of the “experts” that the Sentinel had worked with being interviewed on CNN. He kept talking about the image he had formed in “his mind’s eye” of the facts of the case and how that had informed his opinion that it was not Zimmerman screaming. In other words - he went in with a pre-determined notion that it was Trayvon and then he concluded that it was Trayvon. Big surprise. The CNN info-chick didn’t even question him on it.

Yeah, I sure as hell read it, and it clearly states that their conclusion (for what THAT’S worth, mind you) was that there was only about a 48% chance that the screams heard on the 911 tape were Zimmerman’s....and it goes on to point out the obvious: how that casts serious doubt on Zimmerman’s self-defense claims.

Now.....what did YOU two glean from the same article? Forget the “oh well we can’t be sure due to .......” nonsense they always throw in after the grenade pin has been pulled. Tell me exactly what you took away from this piece.

Particularly when you've got two independent eyewitnesses who say it was Zimmerman. Reminds me of an old "Herman" cartoon: a guy is in the doctor's office with a knife stuck squarely in the middle of his back. The doctor holds up an X-ray and says, "according to this it's in your left ear."

"Reached for comment, Owen told TheDC that he has conducted his own study — “The Owen Study” — of more than 400 different pitches, screams, and voice disguises. The study is unpublished."

This amazing proposition is compelling evidence that Owen, a self-declared "forensic expert," as I implied on another thread, is really a mere huckster and a hired gun.

While he says there is "only" a 48% chance that the screams are Zimmerman, based on no acceptible data, "scientific certainty" that they are not Z means only 51%, also based on no acceptible data.

So Zimmerman is on his back getting his ass kicked by Martin who is on top dishing out the beating and we’re supposed to believe Matin is yealling for help? WTH? Did Martin yell out to get someone to help him with the beatdown?

Did you?

“Dr. James Wayman, a San Jose State University expert in the field of speech science, told The Daily Caller that he questions the grounds on which Owen based his analysis.

Wayman also said he would be willing to testify against the admissibility of Owen’s findings on the grounds that they don’t meet the criteria required for evidence in federal courts.

“There is no history of, or data on, the comparison of a questioned scream to a known speech sample,” Wayman said.

“Even if we were to have Mr. Zimmerman recreate the scream under identical conditions with the same cell phone,” Wayman explained, “it would be difficult to attribute the scream to him without a sample of a similar scream from Mr. Martin under the same conditions. This is clearly not possible.”

Reached for comment, Owen told TheDC that he has conducted his own study — “The Owen Study” — of more than 400 different pitches, screams, and voice disguises. The study is unpublished.

He explained that he has attempted, without success, to obtain a “voice exemplar” from Zimmerman, consisting of recordings of both his speaking voice and a scream.

And Wayman, he said, “assumes that the voice software is not able to make a determination on each voice independently.”

Wayman fired back in a later email exchange. “There is no accepted standard regarding metrics for voice comparisons,” he insisted, “either if done forensically or using automated comparison software.”

This section though down in the article says that the Sentinel’s “expert” could not possibly reach a conclusion based on what he had as a sample.

The only reason this case is being tried in the news media is ratings. Sorry Trayvon got shot, and more sorry for what Zimmerman has to go through.

They were obviously on board with the media when it looked like an innocent young black choirboy had been viciously murdered. After the media’s effort went off the cliff, everything that’s subsequently come to light has supported Zimmerman’s claim of self defense.

Why are all these “experts” weighing in on this relatively trivial matter? Why aren’t similar forgery experts fighting to conduct forensic examinations of the impostor’s credentials as an NBC? His election and wanton destruction of the formerly free United States is the real crime of the millennium, not just of the century.

The Sentinel’s reporting has landed a blow against Zimmerman’s self-defense claims, suggesting that it was Martin, not Zimmerman, who shouted for help before the fatal shot struck the teenager in the chest.

No where in the article do they mention the fact that they have a witness who says Zimmerman was crying out for help.

And, that Martin was on top of him beating his head in. No where do they mention that.

They have a voice analysis that they themselves say is inconclusive (48% match to Zimmerman) which by sleight of hand they then re-interpret as conclusive match to Martin. Dishonest. Bald-faced dishonesty.

Now they have other specialists telling them their conclusions are worthless and again, they reinterpret that as proving that the guy on top was screaming for help, and the guy on bottom getting his head caved in was not... despite witnesses who they fail to mention.

With the DNC media, the more you read the less you know, and the more you know that is flatly untrue. Before you buy a subscription to these people you may as well save yourself the money and just lobotomize yourself.

Y'all are missing the point. I think this "expert" is full of shit, but that's totally beside my original stance that this was a hit piece on Zimmerman...to whit:

"The Sentinel’s reporting has landed a blow against Zimmerman’s self-defense claims, suggesting that it was Martin, not Zimmerman, who shouted for help before the fatal shot struck the teenager in the chest.

"Under contract by the Sentinel, Owen Forensic Services founder Tom Owen compared Zimmerman’s voice on his initial 911 call with the scream heard in the background of the later call. Using his own proprietary biometrics software, Owen determined that the two voices were only “a 48 percent match.”

'Owen said a positive identification would involve a number over 90 percent. “[Y]ou can say with reasonable scientific certainty that it’s not Zimmerman,” he told the Sentinel."

"The scream is central to the case. If Zimmerman was the one screaming, his statement to police that he shot Martin in self-defense after being attacked would be more supportable."

This "news"paper/birdcage liner hires their own voice analysis "expert" who clearly gives them the results they wanted. They lead the story with the above, then (of course, in the interest of what is supposed to be fairness) they quote a contrary point of view, ONLY to end the piece with a snotty rebuttal by their own "expert".

The piece is anti-Zimmerman from top to bottom. If y'all don't get that, sorry.

Don't misinterpret this as my own personal stance. I feel Zimmerman was not only justified, but that he should have emptied his mag into the little sumbitch. That's not the point, however.

I’m confused regarding your analysis of this article, because it’s a dailycaller.com report on an orlando sentinel report that discredits the so-called science of the expert in the sentinel report via an outside expert that spoke to the daily caller.

Nonetheless, I agree with your stance on the main issue completely, so I can see no point in arguing over this particular piece, other than than to say that it appears to be an expert willing to testify that the other expert’s findings and methods are BS.

I think the media just did this on their own. It is in their DNA. Their worldview is that the white, heterosexual man is evil (and doubly so, if they are Christian) and always ready to prey on minorities. Forget the fact that Mr. Zimmerman wasn't exactly a member of the 'ancestor of the Mayflower WASP club', the media had a conclusion to push - and facts be damned. Same as the Duke Lacrosse case.

The Media has once again proven their utter worthlessness. I can't think of a more loathsome group in American society. Yes, there is a criminal class - but they don't masquerade as folks you can trust, while all the time lying and tearing down the foundations of the Nation.

I agree with you (with a few honest exceptions like Fox and C-span).

The Journalism Schools train the future tools to lie, if it serves the radical left cause. How many conservatives, independents, or libertarians are admitted to columbia School of Journalism? If anybody honest sneaks through admissions, they are brutalized by the Obama-type Marxist scumbags who make up the faculty during the years of indoctrination.
