The Problem of F0 and Real-Life Speaker Identification: A Case Study. Boss, D. Forensic Linguistics, 3(1):155-159.
abstract   bibtex   
Guidelines for using voice fundamental frequency (F0) in forensic speaker identification are explored. A gas station holdup case study illustrates applications & difficulties in using F0 evidence. The monitoring camera at the crime scene produced a tape of the perpetrator's voice having a mean F0 of 228 hertz, much higher than subsequent interrogation tapes with a mean F0 of 140 hertz - although there was little doubt the suspect was the criminal. The pitch difference is attributed to stress during the robbery. Implications for using F0 evidence emphasize carefully considering factors that might influence F0 & attempting to obtain reference material under similar conditions as original recordings.
