Speech sound disorders can pose a challenge to communication in children that may persist
into adulthood. As some speech sounds are known to require differential control of anterior …

Purpose Generalizations can be made about the order in which speech sounds are added
to a child's phonemic inventory and the ways that child speech deviates from adult targets in …

Purpose: This study investigates the hypothesis that younger speakers and speakers with
more severe speech sound disorders are more likely to use simpler (undifferentiated) …

Quantification of tongue shape is potentially useful for indexing articulatory strategies arising
from intervention, therapy and development. Tongue shape complexity is a parameter that …

Purpose Children with speech errors who have reduced motor skill may be more likely to
develop residual errors associated with lifelong challenges. Drawing on models of speech …

This study reported adult scores on two measures of tongue shape, based on midsagittal
tongue shape data from ultrasound imaging. One of the measures quantified the extent of …

ABSTRACT Ultrasound Tongue Imaging is increasingly used during assessment and
treatment of speech sound disorders. Recent literature has shown that ultrasound is also …

Objective Previous experimental studies have demonstrated abnormal lingual articulatory
patterns characterizing cleft palate speech. Most articulatory information to date has been …

Previous studies reporting the use of ultrasound tongue imaging with clinical populations
have generally provided qualitative information on tongue movement. Meaningful …

This study describes the criteria that are used in ultrasound to measure the differences
between the tongue contours that produce [s] and [ʃ] sounds in the speech of adults …
