Voiceprirt Identification in the Courtroom
In a recent article appearing in the Journal of Forensic Sciences, J. J. Hennessey and C. H. Romig presented a review of the experiments involving identification by voice-print spectrograms, concluding that the various experiments in the field were conflicting, neither denying nor confirming the validity of voiceprint identification. This disagreement among scientists has had a tremendous affect on the admissibility of voiceprint identification as evidence in judicial proceedings. With one exception, until the end of 1970 evidence of voiceprint identification has been held inadmissible. Since that time, the results of an extensive experiment on voice identification conducted by Dr. Oscar Tosi, Professor of Audiology and Speech Sciences, Michigan State University, have been released and greatly strengthened the argument for the admissibility of voiceprint identification as competent evidence.
