Where did these "experts" come from and who are they working for? The Police or Martin's family?
They "work" for the media. . . I read a defense lawyer blog that totally destroyed the credibility of these supposed "voice analyses" based on a single set of recordings. Basically, true voice analysis requires the subject to be tested using specific controlled testing settings, not by using some copy of a copy of a recording. But the media won't report that part when they can, instead, have "breaking news."
Eta: I think this is the blog I read earlier
