An Investigation of Sagittal Velar Movement and Its Correlation with Lip, Tongue and Jaw Movement
نویسنده
چکیده
This paper examines the correlation between velar movement and the movement of other articulators in the midsagittal plane. A physiological model is proposed, which, while being based on common knowledge, is more extensive than has been used explicitly to explain observed movements of the velum. The model is used to guide the measurements taken from raw articulatory data provided by Electromagnetic Articulograph (EMA). The midsagittal velar movement is then examined for four different sentences by separate speakers and attempts are made to explain the patterns by reference to the model. The data was taken from a database of between 220 and 460 phonetically balanced sentences per speaker. This type of dataset allow general patterns of behavior to be uncovered. One such observation made and discussed in this paper is velum lowering before oral velar stops.

Articulatory organization of mandibular, labial, and velar movements during speech.
It has been shown that articulator movements during speech are adjusted along a number of spatiotemporal dimensions. For example, variations in the extent of lip, jaw, or tongue motion are associated with proportional changes in the respective articulators' peak velocity. Modifications in the timing of lip and jaw actions are apparently constrained, exhibiting relative timing covariation. Sylla...
متن کاملOral Motor Indexes in Iranian 4- to 9-month-old infants: A short report
Introduction: Examination of oral motor indices in infants helps treatment team members identify infants who are delayed in these indices earlier and use the order of occurrence of these indices in normal infants as a criterion for treating infants with motor delay. Literature shows that oral movement indices are different in different races, cultures, and languages. The aim of this study was t...
متن کاملExtracting the Movement of Lip and Tongue During Articulation
A method that extracts the 3-D shape and movement of lip and tongue and displays them simultaneously is presented. Lip movement is easily observable and thus extractable using a camera. However, it is difficult to extract the real movement of tongue exactly because the tongue may be occluded by the lip and teeth. In this paper, we use a magnetic resonance imaging (MRI) device to extract the sag...
متن کاملContribution of tongue lateral to consonant production
Speaking requires the coordinated movements of individual articulators. Understanding each articulator’s contribution to speech is fundamental not only for understanding how speech is produced, but also for optimizing speech assessment and treatment. Our recent work has studied the individual contributions of tongue tip, tongue blade, tongue body front, tongue body back, upper lip, and lower li...
