Maybe you're trying to read too fast. Let's try this again:<quoted text>
Your little wiki paste proved what I was saying. The 2 voice experts that did a analysis for the Sentinel both agreed, it was NOT Zimmerman heard yelling. He even refused to give voice samples so they could match him.
"In recordings of the 9-1-1 calls, yells for help are audible in the background. Zimmerman's family says it was Zimmerman yelling for help, Martin's family says it was Martin yelling for help, and independent audio analysts offer differing opinions as to who was yelling for help."
"Two expert audio technicians, listed as possible witnesses for the prosecution, analyzed the emergency calls made during the altercation and concluded that the screams did not come from Zimmerman."
So what we see is that experts in voice identification could not be conclusive about the voice over the phone, The key word in the second paragraph is "possible witnesses for the prosecution." That means that prosecution went out to find their own so-called experts to say it was Martin screaming for help. It defies eye witnesses and people close to Zimmerman such as his neighbor that it was indeed GZ's voice. It's also counter to Martin's own father who said it was not his sons voice, but later changed his mind for whatever reason.
