Speaker identification by non-native and naïve earwitnesses

Abstract

Untrained Chilean auditors and without knowledge of German must identify, within a sequence of German voices, the voice of a German woman who previously spoke in Spanish with a delay of 2 hours. The statements were spoken by native German students from the University of Regensburg. The results show that the auditors identify the original voice, but inaccurately, by giving, within a scale of 1 to 7 the highest score to the target voice above the others, but with an overall average of 6.1. This reinforces the idea that hearing evidence should only have an indicative value. This text is based on a manuscript presented at the 2010 INGEACUS Congress held in Valdivia, Chile.
