This study explores the use of a computational approach to the elimination of a known from an unknown voice exemplar in a forensic voice elimination protocol. A subset of voice exemplars from 11 talkers, taken from the TIMIT data base, were analyzed using a formant tracking program. Intra- versus inter-speaker mean formant frequencies are analyzed and compared.
