For more details, please download one of Y&J's peer-reviewed articles entitled Legal, Scientific and Forensic Controversies Over Spectrographic Voice Analysis for Identification or Elimination, published in the Law Enforcement Executive Forum  about the legal state of forensic voice identification. This article not only delineates the legal aspects of forensic Voice ID, but it also sets Y&J apart from other Voice ID experts in the U.S. Other Forensic Voice ID research conducted by Y&J include Yonovitz, A., Joe, H.Speaker Identification: Effects of noise, telephone bandwidth, and word count on accuracy.Journal of the Acoustical Society of America, Vol. 128, No. 4, Pt. 2 of 2, Oct. 2010, and presentations at, for examples, the 2nd Pan American / Iberian Meeting on Acoustics (Cancún, Nov. 2010) and the 164th Meeting of the Acoustical Society of America (Oct. 2012).

FORENSIC VOICE IDENTIFICATION/ELIMINATION

to determine if a particular speaker in the questioned audio evidence (or audio track of the video evidence) is the same (identification) or different (elimination) than a “known” recording of a particular person. The reliable principles of this protocol are to provide a basis for voice/speaker identification or elimination that is consistent with the known and well-established principles of the hearing, speech and language sciences. 

Y&J’s generally-accepted, underlying science and reliable methodology for voice/ speaker identification or elimination were utilized long before the decision in U.S. vs. Angleton, 269 F.Supp.2d 892, 904-05 (S.D. TX 2003) (proposed expert testimony on aural spectrographic voice identification method failed to meet Daubert standard for reliability).
