A Comparison of Two Acoustic Methods for Forensic Speaker Discrimination

Clermont, Frantz; Rose, Philip


A pilot forensic-phonetic experiment is described which compares the performance of formant- and cepstrally-based analyses on forensically realistic speech: intonationally varying tokens of the word hello said by six demonstrably similar-sounding speakers in recording sessions separated by at least a year. The two approaches are compared with respect to F-ratios and overall discrimination performance utilising a novel band-selective cepstral analysis. It is shown that at the second diphthongal...[Show more]
