Speech motor coordination and control: evidence from lip, jaw, and laryngeal movements.
The movements of the lower lip, jaw, and larynx during speech were examined for two different speech actions involving oral closing for /p/ and oral constriction for /f/. The initial analysis focused on the manner in which the different speech articulators were coordinated to achieve sound production. It was found that the lip, jaw, and laryngeal movements were highly constrained in their relat...
متن کاملThe physiologic development of speech motor control: lip and jaw coordination.
This investigation was designed to describe the development of lip and jaw coordination during speech and to evaluate the potential influence of speech motor development on phonologic development. Productions of syllables containing bilabial consonants were observed from speakers in four age groups (i.e., 1-year-olds, 2-year-olds, 6-year-olds, and young adults). A video-based movement tracking ...
متن کاملThe sequential development of jaw and lip control for speech.
Vertical displacements of the upper lip, lower lip, and jaw during speech were recorded for groups of 1-, 2-, and 6-year-olds and adults to examine if control over these articulators develops sequentially. All movement traces were amplitudeand time-normalized. The developmental course of upper lip, lower lip, and jaw control was examined by quantifying age-related changes in the similarity of e...
متن کاملIntrinsic velocity differences of lip and jaw movements: preliminary results
The observed kinematics of speech movements are the result of both the control by the brain and the biomechanical properties of the peripheral speech apparatus. For many kinematic phenomena, it is not clear whether they are actively controlled or intrinsic to the biomechanical system. This pilot study investigated the movement of sensors on the lips and the jaw in cyclical vowel transitions at ...
متن کاملSensori-motor Control of Speech Movements
This paper shows how an articulatory model, able to produce acoustic signals from articulatory motion, can learn to speak, i.e. coordinate its movements in such a way that it utters meaningful sequences of sounds belonging to a given language. This complex learning procedure is accomplished in four major steps: (a) a babbling phase, where the device builds up a model of the forward transforms, ...
