One of the most crucial issues facing courts in recent years is the admissibility of novel scientific evidence. There is obviously a strong temptation to use a scientific process or machine that purports to provide unbiased information free from the many competency and credibility problems associated with testimonial evidence. One such process, called spectrographic analysis, is now being favorably received by the courts despite its substantial shortcomings. Spectrographic analysis-popularly known as "voiceprints"- is a technique for the identification of voices with the aid of a machine known as the sound spectrograph. The purpose of this comment is to examine the reliability of this technique to determine if the present state of the art justifies the reliance that has been placed upon it.
