Clermont, FrantzRose, Philip2015-12-132015-12-130814-6039http://hdl.handle.net/1885/91429A 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 target in hello the cepstrum-based analysis outperforms the formant analysis by about 5%, compared to its 10% superiority for same-session data.Keywords: Acoustic noise measurement; Data reduction; Sound recording; Speech analysis; Band-selective cepstral analysis; Speech recognition20012015-12-12
