Articulatory strategy as a source of variation in acoustic vowel dynamics
Patrycja Strycharczuk, Justin J. H. Lo, Sam Kirkham
Acoustic vowel dynamics have some speaker-identifying characteristics, which have been ascribed to individual properties of articulatory strategies: formant transitions have a part…
AURORA Model of Formant-to-Tongue Inversion for Didactic and Clinical Applications
Patrycja Strycharczuk, Sam Kirkham
This paper outlines the conceptual and computational foundations of the AURORA (Acoustic Understanding and Real-time Observation of Resonant Articulations) model. AURORA predicts t…
Dynamical model parameters from ultrasound tongue kinematics
Sam Kirkham, Patrycja Strycharczuk
The control of speech can be modelled as a dynamical system in which articulators are driven toward target positions. These models are typically evaluated using fleshpoint data, su…
Articulatory strategy in vowel production as a basis for speaker discrimination
Justin J. H. Lo, Patrycja Strycharczuk, Sam Kirkham
The way speakers articulate is well known to be variable across individuals while at the same time subject to anatomical and biomechanical constraints. In this study, we ask whethe…
Phonetic accommodation and inhibition in a dynamic neural field model
Sam Kirkham, Patrycja Strycharczuk, Rob Davies +1
Short-term phonetic accommodation is a fundamental driver behind accent change, but how does real-time input from another speaker's voice shape the speech planning representations…
Scaling laws for nonlinear dynamical models of articulatory control
Sam Kirkham
Dynamical theories of speech use computational models of articulatory control to generate quantitative predictions and advance understanding of speech dynamics. The addition of a n…
