“…The Rion EPG (Fujimura, Tatsumi andKagaya 1973, Hiki andItoh 1986) is used in all the studies reporting Japanese cleft palate speech. All EPG systems, including a Linguagraph system developed at the University of Canterbury, UK, by Kelly, Main, Manley and McLean (2000), share some common general features, but differ in details such as the construction of the palates, number and configuration of electrodes, and hardware/software specifications. An essential facility in the investigation of cleft palate speech is to be able to record and display EPG data simultaneously with other channels, such as the acoustic signal and oral/nasal airflow.…”

Abnormal patterns of tongue‐palate contact in the speech of individuals with cleft palate

Individuals with cleft palate, even those with adequate velopharyngeal function, are at high risk for disordered lingual articulation. This article attempts to summarise 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 emphasises the importance of quantifying relevant aspects of tongue-palate contact data.Areas of research requiring further investigation are outlined.

“…To assess tongue-palatal contacts during speech production, speech pathologists often use palatometric tools such as EPG,[19] electromagnetic articulography,[20] computerized tomography (CT),[21] magnetic resonance imaging,[22] and X-ray microbeams,[23] among which EPG [Figure 5] is widely used. EPG is a visual feedback system that records the location and timing of tongue contacts with the hard palate during speech through the use of a grid of sensing electrodes.…”

To appreciate any enhancement in speech following gingivectomy of enlarged anterior palatal gingiva. Periodontal literature has documented various conditions, pathophysiology, and treatment modalities of gingival enlargement. Relationship between gingival maladies and speech alteration has received scant attention. This case report describes on altered speech pattern enhancement secondary to the gingivectomy procedure. A systemically healthy 24-year- female patient reported with bilateral anterior gingival enlargement who was provisionally diagnosed as “gingival abscess with inflammatory enlargement” in relation to palatal aspect of the right maxillary canine to left maxillary canine. Bilateral gingivectomy procedure was performed by external bevel incision in relation to anterior palatal gingiva and a large wedge of epithelium and connective tissue was removed. Patient and her close acquaintances noticed a great improvement in her pronunciation and enunciation of sounds like “t”, “d”, “n”, “l”, “th”, following removal of excess gingival palatal tissue and was also appreciated with visual analog scale score. Exploration of linguistic research documented the significance of tongue-palate contact during speech. Any excess gingival tissue in palatal region brings about disruption in speech by altering tongue-palate contact. Periodontal surgery like gingivectomy may improve disrupted phonetics. Excess gingival palatal tissue impedes on tongue-palate contact and interferes speech. Pronunciation of consonants like “t”, “d”, “n”, “l”, “th”, are altered with anterior enlarged palatal gingiva. Excision of the enlarged palatal tissue results in improvement of speech.

This paper describes an original experimental procedure to measure mechanical interactions between tongue and teeth during speech production. Using edentulous people as subjects, pressure transducers are inserted in their complete denture duplicate. Physiology is respected during sound and pressure recording as with standard complete denture. Original calibration device is also described in order to know what kind of information can be extracted from the data. Then the first results of the pilot experiments are presented.Index Terms-speech production, tongue/palate interaction, complete denture, pressure transducer, tongueCorresponding author : Christophe JEANNIN, INPG laboratoire Gipsa-lab (ex ICP),
