Earwitness Evidence: The Reliability of Voice Identifications

Abstract

This article discusses the reliability of non-expert voice identification evidence. While much attention has been paid to the frailties of eyewitness evidence, little attention has been given to the frailties of ‘earwitness’ evidence, even though it has been tendered in several wrongful conviction cases. The author reviews the results of the empirical literature that has examined the reliability of earwitness evidence. The author also analyzes the principal factors used by Canadian criminal courts to assess earwitness reliability in light of the empirical study of those factors. The general conclusions are that earwitness evidence can often be quite unreliable and that the courts have not always properly assessed its reliability.
