Age-related lip movement repetition variability in two phrase positions
نویسندگان
چکیده
This study examined the relationship between age and lip movement variability across repetitions of an utterance. We applied functional data analysis (FDA) to lip movement data of 15-20 repetitions of a short Swedish phrase from 37 Swedish speakers (19 females, 18 males, 5-31 years) collected with three-dimensional articulography. From each utterance, three different sub-units were extracted semiautomatically by locating consistent kinetic events in the lip movement functions. Results generally showed moderate negative correlations between age and amplitude variability. The longest possible sub-unit, given consistent kinematic events, showed the strongest correlation.

Functional Data Analysis of Lip Movements: Repetition Variability as a Function of Age
This study examined inter-repetition variability of lip movements across repetitions of the same utterance as a function of age in Swedish speakers. Lip movement data of 15-20 repetitions of a short Swedish phrase from 37 typically developed Swedish children and adults (19 females, 18 males, aged 5-31 years) were collected using threedimensional articulography, and submitted to functional data ...
متن کاملA comparative study of kinematic and acoustic age- related variability in speech
In this study, we compared age-related lip movement variability with acoustic variability across repetitions using Functional Data Analysis (FDA). Lip movement and acoustic data of 1520 repetitions of a short Swedish phrase from 50 Swedish speakers were collected. Results showed weak to moderate negative correlations for age and variability in lip movements, phrase duration and sound pressure l...
متن کاملVariations in articulatory movement with changes in speech task.
Studies of normal and disordered articulatory movement often rely on the use of short, simple speech tasks. However, the severity of speech disorders can be observed to vary markedly with task. Understanding task-related variations in articulatory kinematic behavior may allow for an improved understanding of normal and disordered speech motor behavior in varying communication contexts. This stu...
متن کاملStable patterns of articulatory movements across inter-subject variability
The goal of the present study was to test whether models of portions of curves, representing movements of the crucial articulator for production of place in syllables containing labiodental and alveolar gestures for production of obstruents (‘iceberg’ portions of demisyllables), that had previously been found to be stable across different prosodic conditions (Bonaventura, 2003; 2005; 2006; Bona...
متن کاملPain-Induced Impact on Movement: Motor Coordination Variability and Accuracy-Based Skill
Studies on pain are generally conducted for two purposes: first, to study patients with pain who have physical changes due to nerve and muscle lesions, and second, to regain the appropriate kinematic post-pain pattern. The present study aimed to investigate the effect of pain on the coordination variability pattern and throw accuracy. Participants included 30 people with a mean age of 18-25 yea...
