Spectral properties of fricatives: a forensic approach
Natalie Fecher · ExLing Conferences · 2011
This paper reports on the acoustic-phonetic analysis of the voiceless fricatives /s, ʃ, f, θ/ 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 audio-visual ‗face cover‘ corpus that was collected 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.
