Abstract
Individuals with cleft palate, even those with adequate velopharyngeal function, are at high risk for disordered lingual articulation. This article attempts to summarize current knowledge of abnormal tongue-palate contact patterns derived from electropalatographic (EPG) data in speakers with cleft palate. These data, which have been reported in 23 articles published over the past 20 years, have added significantly to our knowledge about cleft palate speech. Eight abnormal patterns of tongue-palate contact are described and illustrated with data from children and adults with repaired cleft palate. The paper also discusses some of the problems in interpreting EPG data from speakers with abnormal craniofacial anatomy and emphasizes the importance of quantifying relevant aspects of tongue-palate contact data. Areas of research requiring further investigation are outlined.
