As an audio forensic expert, one of my day-to-day activities is voice identification and speaker recognition. Primeau Forensics receives calls on a weekly basis from concerned businesses and citizens for help identifying a derogatory voicemail message or threat to an employee or supervisor.
Also common are requests to enhance and clarify fraudulent calls placed to insurance or credit card companies during which a bogus transaction takes place by people impersonating account holders.
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.
