Just Adding Value Using Voice Identification

Just Adding Value Using Voice Identification

Original Release Date: October 27, 2023

In episode four of our Case Studies season, Just Science sat down with Josh Yonovitz, expert witness in forensic audio, to discuss the history of utilizing voice identification in investigations and the current state of forensic audio. 

In the 1960’s, voice identification started being used in forensics, but the original voiceprint analysis used was proven to be inaccurate. Nowadays, forensic scientists use a methodology known as Aural-Acoustic Speaker Identification, which is scientifically accepted, but poorly understood. Listen along as Josh describes components of forensic audio, the software and training needed for forensic voice identification, and how forensic audio analysis has helped solve cases.
