Abstract
Voiceprint identification is used to compare known samples to unknown samples and rest on the premise that the science is as reliable and as accurate as fingerprinting. Examination of voice comparison began as early as 1941 and has continued all the way into present day.
The machine used to compare the voices and produce tangible evidence is called a spectrograph. The printout from the spectrograph machine is called a spectrogram. Whether or not this science and the evidence produced from it are admissible in court during trial is an ongoing battle despite the fact that it has been significantly progressing.
This project is a review and analysis of existing data and literature to determine if voiceprint identification is an accurate and reliable method for identifying an unknown speaker. In addition, this paper will also aim to answer the question whether or not the analysis used in voiceprint identification meets the standards dictated by the courts to be admitted as evidence.
