Objective: Previous research using electropalatography (EPG) identified a compensatory articulation called bilabial-lingual double articulations. These double articulations were produced for bilabials by some speakers with cleft palate and involved closure at the lips occurring simultaneously with complete tongue-palate constriction. However, no normative English EPG data exist to confirm the abnormal status of these double articulations. Design: This study reports normative data for EPG contact during bilabial closure. Acoustic and EPG data were recorded for bilabials in different vowel contexts. Participants: Eight normal English-speaking adults. Measures: One measure identified complete tongue-palate constriction, and a second measure calculated percent contact. Results: There were no instances of complete tongue-palate constriction, though some EPG contact occurred in the lateral regions of the palate. The vowel context significantly affected the amount of contact present, with /i/ having the most and /a/ having the least amount of contact. Conclusion: Complete tongue-palate constriction during bilabials of the type found in bilabial-lingual double articulations is not a feature of normal English speech and can therefore be considered an abnormal articulation pattern. Speech-language pathologists who use EPG in their clinical work should be aware that some lateral contact during bilabial closure is normal.

Abstract This study describes the prevalence of speech problems and the use of augmentative and alternative communication (AAC) in children with cerebral palsy (CP) in Norway. Information on the communicative abilities of 564 children with CP born 1996–2003, recorded in the Norwegian CP Registry, was collected. A total of 270 children (48%) had normal speech, 90 (16%) had slightly indistinct speech, 52 (9%) had indistinct speech, 35 (6%) had very indistinct speech, 110 children (19%) had no speech, and 7 (1%) were unknown. Speech problems were most common in children with dyskinetic CP (92 %), in children with the most severe gross motor function impairments and among children being totally dependent on assistance in feeding or tube-fed children. A higher proportion of children born at term had speech problems when compared with children born before 32 weeks of gestational age 32 (p > 0.001). Among the 197 children with speech problems only, 106 (54%) used AAC in some form. Approximately 20% of children had no verbal speech, whereas ~15% had significant speech problems. Among children with either significant speech problems or no speech, only 54% used AAC in any form.

High speed cinefluorography was used to track articulatory movements preceding and following full-mouth tooth extraction and alveoloplasty in two subjects. Films also were made of a control subject on two separate days. The purpose of the study was to determine the effects of dramatically altering the structural dimensions of the oral cavity on the kinematic parameters of speech. The results showed that the experimental subjects performed differently pre and postoperatively though the changes were in different directions for the two subjects. Differences in both means and variabilities of kinematic parameters were larger between days for the experimental (operated) subjects than for the control subject. The results for the Control subject also showed significant differences in the mean values of kinematic variables between days though these day-to-day differences could not account for the effects found pre- and postoperatively. The results of the kinematic analysis, particularly the finding that transition time was most stable over the experimental conditions for the operated subjects, are used to speculate about the coordination of normal speech.

Ninety-six participants with normal hearing and 63 with severe-to-profound hearing impairment viewed 100 CID Sentences (Davis & Silverman, 1970) and 100 B-E Sentences (Bernstein & Eberhardt, 1986b). Objective measures included words correct, phonemes correct, and visual-phonetic distance between the stimulus and response. Subjective ratings were made on a 7-point confidence scale. Magnitude of validity coefficients ranged from .34 to .76 across materials, measures, and groups. Participants with hearing impairment had higher levels of objective performance, higher subjective ratings, and higher validity coefficients, although there were large individual differences. Regression analyses revealed that subjective ratings are predictable from stimulus length, response length, and objective performance. The ability of speechreaders to make valid performance evaluations was interpreted in terms of contemporary word recognition models.

The premise of this article is that increased understanding of the brain bases for normal speech and voice behavior will provide a sound foundation for developing therapeutic approaches to establish or re-establish these functions. The neural substrates involved in speech/voice behaviors, the types of muscle patterning for speech and voice, the brain networks involved and their regulation, and how they can be externally modulated for improving function will be addressed.

Normal Speech

Obturator prostheses are considered to be the preferred choice for the restoration of maxillary defects. Patients with palatal insufficiency, speech and deglutition becomes impaired, thereby requiring prosthodontic rehabilitation. The prosthodontic rehabilitation of patients with acquired defects of the maxilla after surgical resection is the complete responsibility of a maxillofacial prosthodontist. He has to recreate an artificial barrier between the cavities and thus restore the functional capabilities of speech, mastication and swallowing. Palatal obturator is the only substitute which covers the defect and contributes to normal speech production. It eliminates hypernasality and improves the communication.DOI: http://dx.doi.org/10.3329/updcj.v1i2.13983 Update Dent. Coll. j. 2011: 1(2): 25-28
