Measurements of the fluid flow through a scaled-up model of the human glottis are
presented to determine whether glottal flow may be approximated as unsteady. Time-and …

Phase-averaged and cycle-to-cycle analysis of key contributors to sound production in
phonation is examined in a scaled-up vocal-fold model. Simultaneous temporally and …

This paper ranks the importance of unsteady aerodynamic mechanisms in glottal flow.
Particular emphasis is given to separation point motion, acceleration of glottal airflow by …

A decomposition algorithm that uses a pitch-scaled harmonic filter was evaluated using
synthetic signals and applied to mixed-source speech, spoken by three subjects, to separate …

This thesis is a study of the production of human speech sounds by acoustic modelling and
signal analysis. It concentrates on sounds that are not produced by voicing (although that …

The two principal sources of sound in speech, voicing and frication, occur simultaneously in
voiced fricatives as well as at the vowel-fricative boundary in phonologically voiceless …

The last few decades have witnessed tremendous progress in the performance, reliability,
and wide-spread use of speech-processing devices. Using mathematical models of human …

Based on he first systematic approach to fuzzy speech production modeling, we
demonstrate the effectiveness of the fuzzy control for speech signal generation. The control …

In this paper, the timing of vortex formation on the glottal jet is studied using previously
published velocity measurements of flow through a scaled-up model of the human vocal …

This study estimates glottal waves and vocal-tract area functions (VTAFs) from vowel
sounds. Traditional estimations assume that glottal waves are zero over closed glottal …
