Abstract. Dental rehabilitation by complete dentures is a state-of-the-art approach to improve functional aspects of the oral cavity of edentulous patients. It is important to assure that these dentures have a sufficient fit. We introduce a dataset of 13 edentulous patients that have been recorded with and without complete dentures in situ. These patients have been rated an insufficient fit of their dentures, so that additional (sufficient) dentures and additional speech recordings have been prepared. In this paper we show that sufficient dentures increase the performance of an ASR system by ca. 27 %. Based on these results, we present and discuss three different systems that automatically determine whether the dentures of an edentulous person have a sufficient fit or not. The system with the best performance models the recordings by GMMs and uses the mean vectors of these GMMs as features in an SVM. With this system we were able to achieve a recognition rate of 80 %.

“…Most of the literature on phonetic research in the field of prosthodontics until now has focused on positioning of the artificial teeth and the vertical dimension of occlusion. [2][3][4][5][6][7] Although some studies have reported a relationship between speech and the curvature of the palatal contour of complete dentures, [8][9][10][11][12][13] these studies have focused on the effects on the palatogram [11][12][13] and air pressure, 8 and not on the sound itself. In addition, although several reports indicate that the palatal contour facilitates pronunciation of the /S/ sound, [8][9][10][11] there is not much evidence on the role of the palatal form in complete dentures with much circumstance.…”

Individuals using dental prosthetic appliances tend to mispronounce the /S/ sound, phonation of which depends on the shape of the palatal contour. Thus, prosthodontists need to create the palatal contour in complete dentures with care. Here, we report that by using a speech recognition system, the palatal contour can be easily adjusted in the waxed denture base. AbstractPurpose: This study used a speech recognition system to investigate the intelligibility of the /S/ sound, which is based on the palatal contour of complete dentures. Methods:Six subjects with an edentulous maxilla participated in the study. The experimental dentures were made of self-curing acrylic resin and four curvatures (0, 2, 4, 6 mm) of the palatal contour were evaluated. A speech recognition program automatically converted the phonetic signals into phonetic segment labels. Labels that correctly recognized the /S/ sound were defined, and the distribution of the correct labels was analyzed in relation to the palatal contour. Palatograms were also recorded to assess tongue movement. Results: Repeated-measures one-way analysis ofvariance revealed a significant effect of the curvature of the palatal contour on the appearance ratio of the correct [Si] labels (F=53.1, P<0.05). Tukey's multiple comparisons revealed a significant difference between 0 mm and 2 mm (P<0.001), 0 mm and 4 mm (P<0.001), 2 mm and 6 mm (P<0.001), and 4 mm and 6 mm (P<0.001). Based on the appearance ratios of the [çi] labels, the 0 mm curvature of the palatal contour was rated as yielding the highest intelligibility (P<0.01), and based on those of the [tSi] and [dJi] labels, the 6 mm curvature was rated as yielding the intelligibility (P<0.01 for both). When tongue movement was assessed from the palatograms, tongue contact was found to be similar to that in the typical palatogram for each recognized syllable. Conclusion:The curvature of the palatal contour affects the pronunciation of the /S/ sound, and the appropriate curvature of the palatal contour in complete dentures for correct pronunciation of this sound is 2 to 4 mm.

“…Isto sugere que, quanto maior a idade, maior a discrepância maxilo-mandibular, e assim pode-se inferir que a maioria das crianças classificadas com o índice oclusal 4 e 5, possam ser também, as crianças mais velhas desta amostra. Porém, considerando que ao longo do tempo a função da fala pode se adaptar ao ambiente oral modificado (ICHIKAWA et al, 1995;MCFARLAND et al, 1996;MARINO et al 2005), estas crianças, então, tiveram mais oportunidade de se reorganizar e, neste momento, apresentar uma fala normal sem distorções. Porém, o presente estudo não verificou diferenças estatisticamente significantes nas diferentes idades das crianças incluídas em cada grupo de índice oclusal.…”

“…A utilização de repetição de frases pode ser um bom instrumento para a detecção de distorções na fala, uma vez que a fala dirigida permite a comparação entre os sujeitos em diferentes etapas de tratamento, além de permitir a análise de fonemas em diferentes contextos fonéticos (AMARO, 2006;HASSAN et al, 2007;ALVES, 2008 recorrência para a avaliação da fala, de acordo com a língua falada pelos participantes (ICHIKAWA et al, 1995;SHIRIBERG et al, 1997;WERTZNER et al, 2005 produção do /z/, a posição onset medial é mais facilitadora para sua produção (SAVIO, 2001). Neste estudo, a amostra de fala utilizada foi constituída de palavras em que o /s/ encontrava-se no início da sílaba, e o /z/ na sílaba medial, favorecendo, assim, sua detecção.…”

INTRODUÇÃO:O ceceio tem sido descrito como uma alteração de fala esperada para pacientes com fissura de lábio e palato acompanhado de deficiência de crescimento maxilar. A relação entre as distorções na produção dos sons fricativos linguo-alveolares e a severidade da má oclusão não estão estabelecidos na população com fissura.OBJETIVO: Relacionar a presença de ceceio nos fonemas /s/ e /z/ com a deformidade dentofacial, de acordo com o índice oclusão, em crianças com fissura labiopalatina. METODOLOGIA:A amostra de fala e os modelos de gesso foram obtidos de 106 crianças com fissura labiopalatina operada durante a dentição mista e antes do tratamento ortodôntico. OBJECTIVE:Correlation between lisping and dental arches relationship, according to oclusal index, in children with operated unilateral cleft lip and palate (UCLP). METHODOLOGY:Speech samples and dental arch casts were obtained from 106 children with operated UCLP during mixed dentition and before orthodontic treatment.Video-taped productions of the phrases /u sasi saiw sedu/ and /zizi powzow na kaza da zezε/ were rated by speech-language pathologists for the identification of lisping during /s/ and /z/. Dental arches casts were rated by orthodontists using the occlusal index to establish dental arches relationships. LOCAL:Hospital of Rehabilitation of Craniofacial Anomalies, USP, Bauru -SP, Brazil. RESULTS:Substantial inter-judge agreement during auditory-perceptual ratings of lisping during /s/ and /z/ (kappa = 0.65) and moderate to perfect intra-judge agreement during auditory-perceptual ratings during /s/ e /z/ (k=0.58 -1.00) were found. Almost perfect agreement was found between orthodontists while establishing five-years index (k=0.81).Multiple logistic regression showed no significant association between lisping and occlusal index (p=0.802) and age (p=0.662) for /s/, and between lisping and occlusal index (p=0.252) and age (p=0.755) for /z/. CONCLUSION:This study failed to reveal an association between lisping and dental arches relationship in children with operated UCLP.
