Even based merely on their relative training and experience the defense expert witnesses appear to vastly outclass those brought forward by the State. For example:
State Expert #1, Tom Owens: A one-man audio forensics operation whose highest academic degree is a BA in History, who has no formal academic training in speech recognition or speaker identification, whose standards for analysis are self-written and in any case subject to self-violation in order to ensure a “finding”, who uses as his primary speech analysis tool a computerized “biometric” system in which he has a substantial financial stake, and which in any case he has used for less than two years and tested about as an expert witness only once before.
State Expert #2, Dr. Alan Reich, PhD: A long-retired college professor with an avocational interest in speech recognition and identification who manages to hear words and phrases in audio recordings that cannot be heard by world-leading experts in the field, much less by layman.
Compare and contrast with the defense expert witnesses:
Defense Expert #1, Dr. Hirotaka Nakasone, PhD: A senior scientist with a 17-year career with the Federal Bureau of Investigation, currently the Head of the Bureau’s Voice Recognition Program, and the Head of the international working group establishing the first formal scientific standards for speech recognition and speaker identification.
Defense Expert #2, Dr. J.P. (Peter) French, PhD: Dr. French earned his PhD in the analyses of recorded conversations, he is the Director of J.P. French Associates, the United Kingdom’s longest established independent forensic laboratory specializing in the analysis of speech, audio, and language with 6 full-time scientific staff, and a Professor in the Department of Language and Linguistic Science, University of York.
Defense Expert #3, Dr. George Doddington, PhD: Dr. Doddington conducted his doctoral thesis on speaker recognition, and since 1970 he has been leading the development and evaluation of speech recognition and speaker identification technologies and methodologies at a wide variety of top-level institutions, including Texas Instruments, the Defense Advanced Research Projects Agency (DARPA), the National Security Agency (NSA), and currently at the National Institute for Standards and Technology (NIST). Interestingly, he was deeply involved in the development of the voice recognition technology used in the F-16 fighter aircraft.
