It is reported that the orthognathic patients suffer from not only aesthetic problems but also resonance disorder and articulation disorder because of the abnormality of the oral cavity. These disorders have an influence on the patients' communication and they are usually required to be corrected by orthognathic surgery. Speech of the orthognatic patients is affected by the change of the oral cavity capacity and structures after surgery. This study was designed to investigate the resonance of nasality and the intelligibility of speech for acoustic characteristics of speech for pre and post orthognatic surgery patients.

This study investigated final consonant error characteristics at word-medial position in children with functional articulation disorder. Data was collected from 11 children with functional articulation and 11 normal children, ages 4 to 5. The speech samples were collected from a naming test. Seventy-five words with every possible bi-consonants matrix at the word-medial position were used. The results of this study were as follows : First, percentage of correct word-medial final consonants of functional articulation disorder was lower than normal children. Second, there were significant differences between two groups in omission, substitution and assimilation error. Children with functional articulation disorder showed a high frequency of omission and regressive assimilation error, especially alveolarization in regressive assimilation error most. However, normal children showed a high frequency of regressive assimilation error, especially bilabialization in regressive assimilation error most. Finally, the results of error analysis according to articulation manner, articulation place and phonation type of consonants of initial consonant at word-medial, both functional articulation disorder and normal children showed a high error rate in stop sound-stop sound condition. The error rate of final consonant at word-medial position was high when initial consonant at word-medial position was alveolar sound and alveopalatal sound. Futhermore, when initial sounds were fortis and aspirated sounds, more errors occurred than linis sound was initial sound. The results of this study provided practical error characteristics of final consonant at word-medial position in children with speech sound disorder.

Speech and language functions are highly cognitive and human-specific features. The underlying causes of normal speech and language function are believed to reside in the human brain. Developmental persistent stuttering, a speech and language disorder, has been regarded as the most challenging disorder in determining genetic causes because of the high percentage of spontaneous recovery in stutters. This mysterious characteristic hinders speech pathologists from discriminating recovered stutters from completely normal individuals. Over the last several decades, several genetic approaches have been used to identify the genetic causes of stuttering, and remarkable progress has been made in genome-wide linkage analysis followed by gene sequencing. So far, four genes, namely GNPTAB, GNPTG, NAGPA, and AP4E1, are known to cause stuttering. Furthermore, thegeneration of mouse models of stuttering and morphometry analysis has created new ways for researchers to identify brain regions that participate in human speech function and to understand the neuropathology of stuttering. In this review, we aimed to investigate previous progress, challenges, and future perspectives in understanding the genetics and neuropathology underlying persistent developmental stuttering.

Voice is the most common means for communication, but some people have difficulties in generating voice due to their congenital or acquired disorders. Individuals with speech disorders might lose their speaking ability due to hearing impairment, encephalopathy or cerebral palsy accompanied by motor skill impairments, or autism caused by mental problems. However, they have needs for communication, so some of them use various types of AAC (Augmentative & Alternative Communication) devices in order to meet their communication needs. In this paper, a mobile application for literate people having speech disorder was designed and implemented by developing accurate and fast sentence-completion functions for efficient user interaction. From a user study and the previous study on Korean text-based communication for adults having difficulty in speech communication, we identified functionality and usability requirements. Specifically, the user interface with scanning features was designed by considering the users' motor skills in using the touch-screen of a mobile device. Finally, we conducted the usability test for the application. The results of the usability test show that the application is easy to learn and efficient to use in communication with people with speech disorders.

The purpose of this study is to survey Speech-Language Pathologists' perception on evaluation and treatment of "swallowing disorders". An online questionnaire was sent to the 279 subjects attending undergraduate/graduate programs in speech therapy department and/or SLPs who work in various settings. The survey consisted of three parts: 1) background information and educational/clinical experiences that are associated with dysphagia (swallowing disorder), 2) the current state of diagnosis and treatment of dysphagia of clinical practice (certified SLPs only), 3) the recognition of diagnosis, treatment, education for dysphagia. Each item of the survey was scaled by the participants on a five-point Likert scale of 1 to 5 (1 being not at all and 5 being extremely) or self-reported answers. The results of the survey showed that SLPs have high interest in "swallowing disorder", but most of them regarded them very difficult to diagnose and treat. The reason is that they have not been trained as a swallowing specialist. Therefore it is necessary to provide more opportunities for education and practice to establish the expertise of SLPs.

The present study was performed to investigate the characteristics of breath groups while reading paragraph in normal adults and adult patients with voice disorders. 10 normal females(avr. 20.6 yrs.), 10 young voice disorder females(avr. 33.5 yrs., P1 group), and 10 old voice disorder females(avr. 56.3 yrs., P2 group) read a paragraph of 210 syllables. By using the 'Running Speech' program of the Phonatory Aerodynamic System(PAS), total duration, numbers of breath groups, duration per breath group, and numbers of syllables per breath group were measured, and their correlations with aerodynamic measurement results of reading were analyzed. As a result, in total duration, numbers of breath groups, normals scored highest and P2 group speakers, lowest. Normals showed the longest duration per breath group which was not significant. P2 group speakers showed the highest numbers of syllables per breath group. Correlation analysis showed significantly high correlation scores of total duration and expiratory airflow; numbers of breath groups and inspiratory volume.

The purpose of this study is to examine the prosodic pattern of the children with high functioning autism spectrum disorder(HFASD) according to sentence type. The participants were 18 children aged from 7 - 9 years; 9 children with HFASD and 9 typical development children(TD) of the same chronological age with HFASD children. Sentence reading tasks were conducted in this study. Seven interrogative sentences and 7 declarative sentences were presented to the participants and were asked to read the sentences three times. Mean values of F0, F0 range, intensity, speech rate and pitch contour were measured for each sentence. The results showed that for F0 range, significant main effect and interaction effect were observed in the subject group and sentence type. There were significant differences in intensity, mean F0, speech rate, pitch contour across sentence types. The results of this study indicated that HFASD showed no difference in intonation across sentence types. Speakers' intention may have a negative effect on pragmatic aspects. These results suggest that the assessment and intervention of prosody be important for HFASD.
