Spectral properties of fricatives: a forensic approach

Abstract

This paper reports on the acoustic-phonetic analysis of the voiceless fricatives /s, , / taken from high-quality recordings of six native British English speakers reading phonetically controlled stimuli under various face disguise conditions. Speech samples were extracted from an audiocollected for the purpose of investigating multimodal speech and speaker recognition in a forensic context. Findings are discussed with regard to constraints in speech production and acoustic damping effects caused by certain mask materials.
