Just in case anyone's interested. Here is Mr. Owen's CV. Also, he has testified or been identified as an expert in at least 12 reported decisions over the past decade or so on voice issues. Which means, imo, he's probably testified or issued a report in about 3 or 4 times that many cases. I can't link to the cases b/c they're from a subscription site, so take it fwiw.
He also is "approved" by a lot of media, which is listed in his CV.
