Nelson told the defense the definition of the Frye hearing is to discuss if the voice expert's methodology is widely accepted as scientific or is novel. She limited the the defense's challenge to words the experts heard at this point and told them to  argue whether the methodology is new and novel.

West continued questioning Owen on if he makes money from the software he used in analysis of the 911 calls. Owen said he has made $5,000 in the 2.5 years from sales of software.

Owen then read off what he thought was said on the call, scream-by-scream. Some of the screams he interpreted as saying "I need help" and "I want help."

Owen said the limited sound samples mean he can only say screams not being Zimmerman is  "probable," and that Zimmerman can't be positively excluded or included.

In the state's questioning, they attempted to show Owen's conclusion is a separate issue from his methodology to reach conclusion on the call. Owen said looping the sound samples, which Owen had to do in his analysis of the 911 call, is not new or novel in the field.

Owen said he also tested the portion of Zimmerman's call that was under scrutiny for a possible racial slur and found that Zimmerman said "f****** punks."

Nelson also considered the state's motion to compel defense expert reports and writings. The defense says they have none required for a disclosure but the state says they have doubts. Nelson reviewed defense emails with experts to see if the state should be given any of them and found none were applicable.

Zimmerman is charged with second-degree murder for fatally shooting 17-year-old Trayvon Martin during a struggle in a gated community where he lived. He is pleading not guilty, claiming self-defense.
