Résumé
This article presents the first step in a process to evaluate the potential impact of the physical properties of the articulators on speech perception. The underlying hypothesis is that articulatory biomechanics contribute to shape articulatory and formant trajectories. These in turn become patterns available for speech perception. Perceptual tests on synthetic silent center stimuli were run which are inspired from former studies of Strange and colleagues. Stimuli were generated with a unique timing with different models incorporating various degrees of physical realism. Our results show that silent center stimuli generated with a realistic biomechanical model achieve higher identification scores than stimuli from less realistic, kinematic, models, when only fast reaction times of the listeners are considered, in order to make sure that only low-level cognitive processings are involved.
