The admissibility of the results of voiceprint' analysis as evidence in a criminal trial has received a great deal of attention in the last ten years, both from legal scholars and in the courts. Although a relative newcomer to the field of forensic science, voice spectrography is not a recent development in the field of evidence; Wigmore foresaw the use of a voiceprint as early as 1937, when he suggested that the individuality of a person's voice provided a possible means of speaker identification.
