An audio forensic expert has classroom training, on the job experience and has testified in court. Even though not all audio forensic experts testify, having the knowledge skill and ability to perform scientific analysis of audio recordings is a qualification and requirement as an audio forensic expert.

The unknown voice is Mayor Jim Fouts. I performed two forms of voice identification testing (also known as speaker recognition) with a second audio forensic expert employed with Primeau Forensics. We performed both aural spectral voice ID as well as biometric voice identification testing.
The biometric software program that we used is a Speech Pro Product titled ?SIS 2?. We formatted each speech sample based on training received from Owen Forensic Services and loaded them into the biometric software. The result was a 98% mismatch meaning the ?unknown? voice recording that surfaced in the Washington Post today is NOT the voice of Donald Trump.
