Visual perception of anticipatory rounding gestures

Perceiving anticipatory phonetic gestures in French

Positing that listeners exploit early motoric cues and vocal tract shapes related to upcoming speech elements, this research examines the perceptual effects of anticipatory gestures and vocal tract configurations in the production of a French rounded vowel-like consonant: the so-called semivowel [Á]. The paradigm consists in generating speech samples by a representative French speaker, then seg...

Controling anticipatory behavior for rounding in French cued speech

“Langage Parlé Complété (LPC)” is the French manual system – corresponding to Cued Speech – used to complement lip reading and thus enhance speech perception for hearing-impaired people. In an anticipatory rounding context, a French speaker was audiovisually recorded while pronouncing and coding [i#yi] sequences with two different pause durations. The effect of pause duration on hand and lip te...

Perception of Coproduced Speech Gestures

In this paper, coarticulatory variations were first obtained with a speech gesture coproduction model. Then, we investigated the perceptual effects of the variabilities using stimuli synthesized with an acoustic tube model deduced from acoustic theory, the DRM model. Perceptual tests showed that the ears tolerate such variations to a considerable degree.

Perception of Anticipatory Time in Temporal Discounting

Effects of Visual Cues of Object Density on Perception and Anticipatory Control of Dexterous Manipulation

Anticipatory force planning during grasping is based on visual cues about the object's physical properties and sensorimotor memories of previous actions with grasped objects. Vision can be used to estimate object mass based on the object size to identify and recall sensorimotor memories of previously manipulated objects. It is not known whether subjects can use density cues to identify the obje...
