Background: Ultrasound Tongue Imaging (UTI) is growing increasingly popular for assessing and treating Speech Sound Disorders (SSDs) and has more recently been used to qualitatively investigate compensatory articulations in speakers with cleft palate (CP). However, its therapeutic application for speakers with CP remains to be tested. A different set of developments, Visual Articulatory Models (VAMs), provide an offline dynamic model with context for lingual patterns. However, unlike UTI, they do not provide real-time biofeedback. Commercially available VAMs, such as Speech Trainer 3D, are available on iDevices, yet their clinical application remains to be tested. Aims: This thesis aims to test the diagnostic use of ultrasound, and investigate the effectiveness of both UTI and VAMs for the treatment of SSDs associated with submucous cleft palate (SMCP). Method: Using a single-subject multiple baseline design, two males with repaired SMCP, Andrew (aged 9;2) and Craig (aged 6;2), received six assessment sessions and two blocks of therapy, following a motor-based therapy approach, using VAMs and UTI. Three methods were used to measure therapy outcomes. Firstly, percent target consonant correct scores, derived from phonetic transcriptions provide outcomes comparable to those used in typical practice. Secondly, a multiplephonetically trained listener perceptual evaluation, using a two-alternative multiple forced choice design, to measure listener agreement provides a more objective measure. Thirdly, articulatory analysis, using qualitative and quantitative measures provides an additional perspective able to reveal covert errors. Results and Conclusions: There was overall improvement in the speech for both speakers, with a greater rate of change in therapy block one (VAMs) and listener agreement in the perceptual evaluation. Articulatory analysis supplemented phonetic transcriptions and detected covert articulations and covert contrast as well as supporting the improvements in auditory outcome scores. Both VAMs and UTI show promise as a clinical tool for the treatment of SSDs associated with CP.

Summary Objective The purpose of this study was to describe the early vocalization skills in children with cleft lip and palate (CLP) at 6 and 12 months of age and compare these early vocalization measures to later speech and vocabulary development at 30 months of age. Methods The participants in the study included 13 children without cleft lip or palate (NCLP) who were typically developing and 13 children with CLP matched for age, gender and socioeconomic status. Standardized measures of cognition, language, hearing, and prelinguistic vocalization measures were administered at 6 and 12 months and speech production, and vocabulary measures were collected at 30 months of age. Results Group differences were observed in both receptive and expressive language development at 12 and 30 months of age. Group differences were observed in the frequency of babbling and Mean Babbling Level at 12 months and speech sound accuracy and vocabulary production at 30 months of age. Significant correlation coefficients were observed between babbling frequency at 6 months and consonant inventory size, vocabulary at 30 months for the children with clefts and PCC-R for noncleft children. Conclusions This study documented that young children with clefts have persistent vocalization and vocabulary deficits well beyond palate closure. Measures of babbling frequency, Mean Babbling Level and consonant inventories provide clinically effective means of identifying these early deficits. Additionally, these measures may provide a tool for monitoring the effects of early intervention programs that promote facilitation of sound and vocabulary development.

Bereits im frühen Kindesalter zeigen Kinder mit Spaltbildungen im Vergleich zu Kindern ohne Spaltbildungen eine veränderte Sprachentwicklung. Untersucht wurden die Möglichkeiten einer von Geburt ansetzenden Sprachförderung von Kindern mit Spaltbildung unter intensiver Zusammenarbeit mit den Eltern im Hinblick auf eine physiologische Sprachentwicklung. Innerhalb der Arbeit wurde ein sprachliches Frühförderkonzept für Kinder mit Lippen-, Kiefer-, Gaumenspalte (LKG) für die Zeit der ersten zwei Lebensjahre entwickelt und mit sieben Kindern mit LKG (Untersuchungsgruppe) in Form von Hausbesuchen erprobt. Im Alter von zwei Jahren wurde die Sprachentwicklung dieser Kinder mit sieben Kindern ohne Spaltbildung (Vergleichsgruppe) verglichen. Für die Auswertung der Untersuchungen kamen die Testverfahren ELFRA-1, ELFRA-2 und SETK-2 sowie eine informelle Prüfung des Lautbestandes zum Einsatz. Die Ergebnisse bestätigten bei fünf Kindern der Untersuchungsgruppe Unterschiede im sprachlichen Entwicklungsverlauf, die sich in Tendenzen zu Sprachentwicklungsrückständen bzw. Auffälligkeiten auf phonetisch-phonologischer Ebene niederschlugen. Deutlichere Hinweise auf Symptome der Gaumenspaltensprache gab es nur bei zwei Probanden. Zwei Kinder der Untersuchungsgruppe zeigten eine altersgerechte sprachliche Entwicklung. Möglicherweise sind diese positiven Ergebnisse auch auf die frühe sprachtherapeutische Förderung zurückzuführen. Zukünftig müsste die Wirksamkeit frühsprachlicher Förderkonzepte anhand von größeren Probandengruppen und längerem Förderzeitraum untersucht werden. / Even in the earliest stages of speech and language development children with cleft lip and palate show differences compared to children without clefts. This study focussed on encouraging early speech development of children with cleft lip and palate and investigated an intensive cooperation between speech pathologist and parents straight after birth up to the age of two years. An early intervention speech program was developed for the first two years of life and tried out on seven children with cleft lip and palate (research group). At the age of two the speech and language development of these children was compared to seven children without clefts (control group). For the time of the investigation the speech pathologist visited the families at home on a regular basis. Evaluation was done with the help of the following instruments: parent questionnaire ELFRA-1, ELFRA-2, language test SETK-2 and an informal screening of the childrens’ sound inventory. The results show differences in speech development in five children with clefts that are reflected in tendencies for delayed speech development and decreased phonological abilities. However, only two children of the research group showed distinctive signs of cleft palate speech. Two children of this group even had speech and language outcomes without pathological findings. Tentatively, these positive results may also be attributed to the effects of the early speech intervention. In future, the effectivity of such programs must be evaluated by researching larger groups of children over a longer period of time.

The diploma work was based on the evaluation of dental casts of patients with bilateral cleft lip and palate (BCLP) with a mean age of 10. Patients consist of two groups, patients without defect in speech and with speech impairment (palatolaly). Palatolalies in the literature are primarily associated with velopharyngeal insufficiency. The study tested the working hypothesis that in the failure of speech is involved a different, specific in some way, palatal shape. Dental casts were scanned using a laser scanner and analyzed by 3-D geometric morphometry and multivariate statistics: principal component analysis (PCA), linear regression analysis and finite element analysis (FESA). Using linear regression it was found that the shape of the palate is affected in younger individuals by age, and so had to be 5 patients excluded for further analysis. Patients with palatolaly have lower variability the palatal shape than patients without palatolalie, so their palates are similar to each other and have a specific shape. Palates are wider and lower than in individuals without speech disorder and they have a characteristic deepening behind the anterior part of the palate. We assume that these features in palate morphology primarily the lower arch and the substantial deepening are most likely to affect the...
