Do you know when Travon’s dad changed his mind about telling detectives that it wasn’t his son screaming? Or was that a false report or something? I gather that the family now thinks it is him. Has the father talked about it anywhere? I haven’t been following the story very closely.

This is what I found on another forensic audio expert’s site:

“The following are the standards accepted nationally by all professional organizations involved with voice identification, including the FBI, the Audio Engineering Society, the International Association for Identification, and the American Board of Recorded Evidence:
IDENTIFICATION: At least 90% of all comparable words must be very similar aurally and spectrally, producing not less than twenty (20) matching words. The voice samples must not be more than six (6) years apart.
PROBABLE IDENTIFICATION: At least 80% of the comparable words must be very similar aurally and spectrally, producing not less than fifteen (15) matching words.
POSSIBLE IDENTIFICATION: At least 80% of comparable words must be very similar aurally and spectrally, producing not less than ten (10) matching words.
INCONCLUSIVE: Falls below either the Possible Identification or Possible Elimination confidence levels and/or the examiner does not believe a meaningful decision is obtainable due to various limiting factors.
POSSIBLE ELIMINATION: At least 80% of comparable words must be very dissimilar aurally and spectrally, producing not less than ten (10) words that do not match.
PROBABLE ELIMINATION: At least 80% of the comparable words must be dissimilar aurally and spectrally, producing not less than fifteen (15) words that do not match.
ELIMINATION: At least 90% of the comparable words must be very dissimilar aurally and spectrally, producing not less than twenty (20) words that do not match.”
If these are the criteria, then 48% would be inconclusive. It seems odd that Tom Owen would state an opinion that it was Zimmerman’s voice.
There seems to be an awful lot of disinformation out there. I don’t know why folks can’t wait until the Grand Jury does its work. It is so disgusting how this young man’s tragic death is being used by political leeches like Sharpton.
