Disyllabic parameterisation of Vietnamese tonal F0 trajectories in likelihood ratio-based forensic voice comparison

Carne, Michael; Ishihara, Shunichi


The paper presents a preliminary investigation of the performance of acoustic-phonetic based forensic voice comparison features derived from tonal fundamental frequency (F0) trajectories parameterised over disyllabic words, rather than individual syllables as is typically done. Its aim was to see whether the disyllabic parameterisation led to any improvements in the validity and reliability of the voice comparison using speech data from 10 native Vietnamese speakers. Polynomial functions were...[Show more]
