Trayvon Martin shooting: It's not George Zimmerman crying for help on 911 recording, 2 experts say

As the Trayvon Martin controversy splinters into a debate about self-defense, a central question remains: Who was heard crying for help on a 911 call in the moments before the teen was shot?

A leading expert in the field of forensic voice identification sought to answer that question by analyzing the recordings for the Orlando Sentinel.

His result: It was not George Zimmerman who called for help.

Oh yea, Zimmerman is on his back getting his face rearanged and head slammed into the concrete by Martin who is on top of him and wee need to believe Martin is screaming for help.

'what specific sample of Zimmerman's voice was used to compare to the 911 call (made by a resident) that contained the screams.'

The 'sample' is from Zimmerman calling the non-emergency number to report on TM.

Respectfully, you don’t understand.
There were a number of calls to 911 during the fatal encounter. One is from a woman who lives in the complex and the struggle was taking place in back of her unit.
As she is speaking to 911 you can hear Zimmerman screaming for help.

Paid experts have told us the world would have burned up by 2010.

I can’t believe that no one has a voice mail or message left on an answering machine of Trayvon. Don’t cell phones have it so you record your own outgoing message for people to leave you a message. Like This is so and so, leave a message?

Man, these guys just keep coming don’t they!

Voice recognition software can identify it was Zimmerman or not. I believe it was Zimmerman.

From Owen Forensic Services, LLC/Forensic Articles;

III - THE METHOD OF VOICE IDENTIFICATION:

"The first step is to evaluate the recording of the unknown voice, checking to make sure the recording has a sufficient amount of speech with which to work and that the quality of the recording is of sufficient clarity in the frequency range required for analysis. The volume of the recorded voice signal must be significantly higher than that of the environmental noise. The greater the number of obscuring events, such as noise, music, and other speakers, the longer the sample of speech must be. Some examiners report that they reject as many as sixty percent of the cases submitted to them with one of the main reasons for rejection being the poor quality of the recording of the unknown voice"

Thanks for that link——most helpful.

Who are you going to believe the “expert” or your lying eyes.

As a former Prosecutor of 25 years I am stunned Zimmerman wasn’t charged with Manslaughter. There is way more than enough probable cause to do so. I certainly expect he will be by the Special Prosecutor. I think 2nd Degree Murder is going to far, but this is somewhere between Involuntary and Voluntary.

An easy call.

[TexasFreeper2009]

why would the guy on top beating the other guy be yelling for help? that makes no sense.

[Keith in Iowa]

“Experts” will say whatever the person signing their check wants them to say.

[Cboldt]

-- The very fact that the prosecutor refused to press charges tells you everything you need to know. --

Yep. And an impatient agitator (Crump) took advantage of the media's proclivity.

Florida's legislature has done a good job of protecting the people. Police officers get a different sort of immunity, but they (the state) can be sued so the case is heard in court. But more evidence is necessary to justify dragging an average citizen in on a "self defense charge." Plus, the state is liable to the citizen from bringing unwarranted charges. The "stifle the Nifongs" clause.

[Jaded]

Al and Jessie would NEVER let that be heard.

Load of horse shit. unfortunately I’m at a party in Palm Springs to give a full explanation but the long and short is that voice is transmitted in waves.

Those waves actually change over different mediums. in order to reach a 90% accuracy you would need to sample an original wave directly from Fisherman.

They are comparing wave signals over cell which are vastly different than those over land lines.

In fact, a land kindling transmission is more accurate to the original wave of the spoken voice than cellular which shorten the wave initially and actually becomes erratic over than various mediums a cell phone travereses .

This guy is ginning garbage for an anterior self serving motive

It’s hard to believe a newspaper like the Tribune would post a story like this unless they completely vetted the so called experts. Yet, I believe this whole incident will be a watershed in the history of journalism. This is far bigger than the Duke fiasco. Because of stories like this, innocent people may die. If they don’t have this story right, I pray for the soul of the editor who allowed this to be published.
