Task Dependent Jaw-lip Coordination Examined by Jaw Perturbation during Bilabial-consonant Utterances

The present study shows experimental results concerning compensatory movements for jaw mechanical perturbations during bilabial utterances. First experiment compares the differences in compensatory responses during sustained utterances of = =, for which lip constriction is required, and of =a=, for which lip and jaw are relatively relaxed. The upper lip downward displacement associated with jaw...

Rapid Change in Articulatory Lip Movement Induced by Preceding Auditory Feedback during Production of Bilabial Plosives

BACKGROUND There has been plentiful evidence of kinesthetically induced rapid compensation for unanticipated perturbation in speech articulatory movements. However, the role of auditory information in stabilizing articulation has been little studied except for the control of voice fundamental frequency, voice amplitude and vowel formant frequencies. Although the influence of auditory informatio...

Articulatory Coordination in Coronal Stops:

Articulatory data obtained from X-ray films were analyzed to investigate articulatory coordination in Swedish vowels and dental and retroflex stops. Several quantitative frameworks for predicting observed tongue contours were evaluated. Performance was assessed on a set of articulations traced at the V1:C boundary in V1:CV2 sequences. The best model, as determined by an rms-criterion, had 3 par...

Model of the mechanical linkage of the upper lip-jaw for the articulatory coordination

The present study considers the muscle impedance control of upper lip-jaw coordination for jaw mechanical perturbations during bilabial utterances. When we perturbed jaw movement for the / / utterance in the carrier sentences of ”kono a a a mitai”, labial distance was recovered quickly by the downward shift of the upper lip [8]. Initial downward shift (40ms after the load onset) of the upper li...
