This Just Science podcast episode provides the audio and transcript of a discussion on the history of using voice identification in investigations and the current state of forensic audio.
This fourth episode of Just Science Podcast’s Case Studies season features Josh Yonovitz, an expert witness in forensic audio, to talk about voice identification in investigations since the 1960s and the current state of forensic audio. The discussion covers the beginning of voice identification’s use in forensics, which used a method of voiceprint analysis that was later proven to be inaccurate, through the presently used methodology known as Aural-Acoustic Speaker Identification. Yonovitz explains this current, scientifically accepted method, describing components of forensic audio, the software and training required for forensic voice identification, and how forensic audio analysis has helped solve cases.
