9:24 a.m.
Mantei asks him about the difference between the aural and automatic approach. Nakasone says the computer technology still must be supervised by trained examiners.

Mantei asks him about conducting and analysis and what is looked for. Nakasone says they first evaluate the suitability of the data and to check the speech sample for issues like “unnatural voicing.”

He says the when the speech is determined to be natural, they check the data. It must be 30 seconds. When a speech sample is 10 seconds, the analyst determines it is not good enough

Nakasone says they use two samples – the recording and the suspect voice.

Mantei asks about the way the speech is expressed and other environmental factors.

Nakasone says the effects of distance to the voice are regarded as something to be careful of. He says when a person is in the far end of a room, captured on a recording, it is called far-field voice with a weak signal and other noise mixed with it.

I hope this pisses off Nelson due to her time being wasted and her being taken for a fool by the prosecution.

I think they're shooting for "there's no way to prove the screams for help were Zimmerman's", while avoiding the rest of the sentence "...because there's no way to prove it is or is not anyone in particular".

Nakasone may help the state merely by showing they attempted an investigation into the voice comparisons, made an effort to complete the investigation ....adds number of witnesses, a state professional expert, time to the trial, the impression a trial was necessary.

A point here is also he will tell us he can't say it was George or Trayvon.

He just discredited the witnesses who thought it was a child's voice. LOL

9:31 a.m.
Mantei asks about the samples from the case. Nakasone was given samples from the case to analyze in March 2012. He says eight recordings were delivered in a CD.

Mantei asks about the recording with screaming and yelling heard in a 911 call. Nakasone says he listened to entire recording, as part of standard operating procedures. He lists the duration of each portion of the call – the screaming, conversation between the dispatcher and woman, gunshot audio event. He says with those areas discounted, there was about 2.3 seconds of screaming. He says other voices overlapped about 16 seconds of the rest of the screaming portion.

Nakasone says he concluded the sample was not fit for the purpose of voice comparison based on research and common sense understanding in the scientific community.

Dr.Hiro knows his stuff, he's the 23rd witness the state has called. Although this type of testimony is so vital, I hope none of the jurors' eyes are glazing over, as can happen with very technical descriptions. Nevertheless we need to hear it. I, over the years, have often worried about the amount of information the average jury will take on board. I saw this myself several years ago in a very technical (and very important) case, and to be honest some members of the jury's eyes were glazing over half way through the breakdown of expertise etc.

Dr. Hiro says that a male voice is usually set on average by the age of 20, though I expect it's not an exact science.

Welcome SheStone!!

Nakasone says signal to noise ratio was also a problem with the recording.

He says it is common belief in the scientific community an attempt to guess the age of a recorded person is complicated. They can approximate, but people make mistakes, adding that people can sound young but turn out to be older.

“Guessing age is a little complicated,” Nakasone says.

Nakasone says defines pitch. He says small children will have high pitch. He describes situations of extreme emotional states and says pitch is known to get higher.

Mantei asks if Nakasone has ever done age testing. He says it occurred to him, but it was not possible to do in this case. He has done it before in the past, he says.

Mantei asks about complicating factors, like the recording quality, for determining age. Nakasone says accuracy of determining someone’s age is about the same as listening to live voice.

I was just curious to know if anyone on here has determined, in their own mind, what they think the outcome of this trial will be?

My thoughts so far are, that he will be acquitted.

Thanks to all for welcoming me.

Based on evidence.. he should be acquitted....

Based on all the nonsense we have seen for past year it's a toss up

The 'familiar' voice scenario makes a whole lot of sense - all of us can change how we sound when we speak normally as opposed to how we may speak, for example, in court or during an interview, and certainly in a rage or screaming.

9:48 a.m.
Nakasone says there are two types of listening – familiar and unfamiliar recognition. Familiar is when you recognize voices of coworkers talking around the corner. Unfamiliar is listening to phone calls of a salesman you don’t know.

In forensic circumstances, Nakasone says they are given a voice from an incriminating recording and also a voice of the suspect. He says when he attempts to compare the two unfamiliar voices it is very difficult because the examiner doesn’t have any stored information about the speech features of the voices being listened to.

He says mathematical models in computer software must be used to help examiners.

Mantei asks about having people familiar to the voices listen to the recordling. Nakasone says in this case, it is better for familiar voice recognition. He says when we listen to a person’s voice, we store their features in our brain and can use them when confronted to compare.

“For this particular case, best approach would be familiar voice recognition from people who heard him in all aspects of life,” Nakasone says.

Mantei finishes questioning. Defense attorney Don West rises to question.

It does sound like the State is setting up Sybrina's testimony.

That's a huge risk, though, as it also sets up Robert, Gladys, and Robert Zimmerman, Jr. all to testify.

I would think acquittal, but at worst hung jury. You never know though.
