Speech Patterns in a Muscular Hydrostat: Lip, Tongue and Glossectomy Movement
This paper aims to use the muscular hydrostat model to explain patterns of strain and motion in soft tissue structures of the oral cavity. The lips and tongue are both muscular hydrostats in that they are composed entirely of soft tissue and moved by local deformation. Muscles are organized in orthogonal directions, which allow finely controlled and reciprocal motion. The structures also are vo...
متن کاملIncreased midsagittal tongue velocity as indication of articulatory compensation in patients with lateral partial glossectomies.
BACKGROUND The purpose of this study was to describe the impact of partial lateral glossectomy on midsagittal tongue movement during speech. METHODS Using B-mode ultrasound, the midsagittal tongue movement of 10 patients with lateral partial glossectomy during a standardized reading passage was analyzed before and after surgery. Six normal adults served as control speakers. The main outcome m...
متن کاملPatterns of variance in /s/ during normal and glossectomy speech
The production of speech includes considerable variability in speech gestures despite our perception of very repeatable sounds. Variability is seen in vocal tract shapes and tongue contours when different speakers produce the same sound. This study asks whether internal tongue motion patterns for a specific sound are similar across subjects, or whether they indicate multiple gestures. There are...
متن کاملAutomatic prediction of tongue muscle activations using a finite element model.
Computational modeling has improved our understanding of how muscle forces are coordinated to generate movement in musculoskeletal systems. Muscular-hydrostat systems, such as the human tongue, involve very different biomechanics than musculoskeletal systems, and modeling efforts to date have been limited by the high computational complexity of representing continuum-mechanics. In this study, w...
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...
