Background No consensus exists on the optimal treatment protocol for orofacial clefts or the optimal timing of cleft palate closure. This study investigated factors influencing speech outcomes after two-stage palate repair in adults with a non-syndromal complete unilateral cleft lip and palate (UCLP). Methods This was a retrospective analysis of adult patients with a UCLP who underwent two-stage palate closure and were treated at our tertiary cleft centre. Patients ${\geq}17$ years of age were invited for a final speech assessment. Their medical history was obtained from their medical files, and speech outcomes were assessed by a speech pathologist during the follow-up consultation. Results Forty-eight patients were included in the analysis, with a mean age of 21 years (standard deviation, 3.4 years). Their mean age at the time of hard and soft palate closure was 3 years and 8.0 months, respectively. In 40% of the patients, a pharyngoplasty was performed. On a 5-point intelligibility scale, 84.4% received a score of 1 or 2; meaning that their speech was intelligible. We observed a significant correlation between intelligibility scores and the incidence of articulation errors (P<0.001). In total, 36% showed mild to moderate hypernasality during the speech assessment, and 11%-17% of the patients exhibited increased nasalance scores, assessed through nasometry. Conclusions The present study describes long-term speech outcomes after two-stage palatoplasty with hard palate closure at a mean age of 3 years old. We observed moderate long-term intelligibility scores, a relatively high incidence of persistent hypernasality, and a high pharyngoplasty incidence.

The present study is a basic study for application of Augmented Reality (AR) to verb teaching for children with language developmental disorders and is intended to examine validity for the list of verbs at the beginning of development. To confirm the validity of the verbs list, the appropriateness of the verbs was evaluated by three professors with certification of KSLP (Korean Speech-Language Pathologist) working in the department of Speech-Language Pathology at the university. The motion validity test was conducted by showing motion implemented as AR to eight master's students in Speech-Language Pathology major, having them record verbs that came to their mind, and evaluating in the conformity. The second motion validity test was conducted by using 5-point Likert scales to 87 undergraduates in Speech-Language Pathology major and having them see the motions in AR and marked the degrees to which them see the motions conform to the relevant verbs on the scales. Using the SPSS 21.0 program, descriptive statics analyses of the results were conducted. Through this all process, thirty verbs were selected as having content validity. It could be seen that when AR based communication system are applied, things and backgrounds that complement the insufficient movements of motions and help motion recognition should be also provided. In future studies, the 3D images of the AR based communication system will be complemented and the content validity will be verified with typically developing children and the children with language developmental disorders.

The purpose of this study was to determine a correlation between acoustic and perceptual parameters of the singing voice in singing students and compare them with the results with previous studies, and a more sensitive parameters in analyzing professional vocal usage. This study measured acoustic and perceptual parameters in 41 singing students. Digital audio recordings were made in sung vowels acoustic analysis. Each sample was judged by 1 experienced singing teacher and 1 voice pathologist on two semantic bipolar 7-point scales (ringing-dull, rich-thin). The results showed that SPP1 (p<0.01), SPP2 (p<0.01), and P1(p<0.01) had significant correlations with ringing and richness quality.

Background and Objectives : The purpose of this study was to examine objectively pre and post operative voice quality evaluation and intelligibility of alaryngeal voice using speech recognition program, HUVOIS. Materials and Methods : 2 laryngologists and 1 speech pathologist were evaluated 'G', 'R', 'B' in the GRBAS sclae and speech intelligibility using NTID rating scale from standard paragraph. And also acoustic estimates such as jitter, shimmer, HNR were obtained from Lx Speech Studio. Results : Speech recognition rate was not significantly different between pre and post operation for pathological vocie samples though voice quality(G, B) and acoustic values(Jitter, HNR) were significantly improved after post operation. In Alaryngeal voices, reed type electrolarynx 'Moksori' was the highest both speech intelligibility and speech recognition rate, whereas esophageal speech was the lowest. Coefficient correlation of speech intelligibility and speech recognition rate was found in alaryngeal voices, but not in pathological voices. Conclusion : Current study was not proved speech recognition program, HUVOIS during telephone program was not objective and efficient method for assisting subjective GRBAS scale.

Background and Objectives : Pediatric vocal health problems are relatively common. However, it is not yet well studied whether uniform diagnosis and treatment is done properly in South Korea. The purpose of this study was to investigate the methods that the Korean speech therapists use to diagnose and treat pediatric voice problem. Materials and Method : An anonymous online questionnaire was administered to 32 speech language therapists registered at the Korean laryngeal speech linguistics society detailing demographics, employment institution, general management of pediatric patients with vocal problem including assessment and treatment procedures. Results : Current practice patterns were analyzed on 32 speech language therapists providing services in South Korea mostly working at tertiary university hospital. One third of pediatric patients were assessed without proceeding to treatment. One fifth of patients were treated without assessment. Perceptual assessment was the main pretreatment assessment methods used. Treatment was done in the following order : Voice rest, SOVT, yawn-sigh and resonant voice. Post-treatment evaluation was used in the following order : Instrumental assessment, clinical judgment, and recording comparison. Conclusion : Speech language therapists practice in South Korea mostly follows the ASHA practice guidelines. However, there are still great amount of cases in which only the evaluation was done without appropriate treatment. Further research is needed to make SPLs more systematic and efficient for evaluating and treating pediatric vocal patients.

The purpose of this study was to compare professional (Pro) and non-professional (Non-pro) voice users with voice disorders in self-reporting voice evaluation using Korean-Voice Handicap Index (K-VHI) and Korean-Voice Related Quality of Life (K-VRQOL). In addition, those were compared by voice quality and voice disorder type. 94 Pro and 106 Non-pro were asked to fill out the K-VHI and K-VRQOL, perceptually evaluated on GRBAS scales, and divided into three types of voice disorders (functional, organic and neurologic) by an experienced speech-language pathologist and an otolaryngologist. The results showed that the functional (F) and physical (P) scores of K-VHI in Pro group were significantly higher than those in Non-pro group. As the voice quality evaluated by G scale got worse, the scores of all aspects except emotional (E) of K-VHI and social-emotional (SE) of K-VRQOL were higher. All scores of K-VHI and K-VRQOL in neurologic voice disorders were significantly higher than those in functional and organic voice disorders. In conclusion, professional voice users are more sensitive to their functional and physical handicap resulted by their voice problems and that goes double for the patients with severe and neurologic voice disorders.

Recently, the Lax Vox voice therapy has been used as one of the SOVTE(Semi-Occluded Vocal Tracts Exercise). The purpose of this study was to explore the effect of Lax Vox voice therapy for a patient with Spasmodic dysphonia on voice improvement. One female spasmodic dysphonia patient(age=27) who had been diagnosed by a laryngologist received Lax Vox voice therapy. The Lax Vox protocol was configured as 5 steps (1 warm-up and 4 steps : bubbling without / with phonation/ gliding with phonation/ generalization) in this study. A total of 11 sessions were performed by a certified speech language pathologist. The present study evaluated the acoustic, aerodynamic, auditory perceptual, and patient's self-rating between pre-, mid-, and post- voice therapy. All objective and subjective parameters were improved after voice therapy; Reduced frequency variation, increased maximum phonation time, enlarged voice range, improved 'G' and 'S' in GRBAS & USDRS, and reduced VHI were observed. Especially, decreased $f_0$ and remarkably reduced voice tremor were also demonstrated following Lax Vox voice therapy. Accordingly, Lax Vox voice therapy technique can be useful for improving voice and quality of life in patients with spasmodic dysphonia.

This study was conducted to determine the degree of satisfaction and the demand for the current education service of language therapy. We surveyed a total of fifty two nurturers of children who had been diagnosed as autistic. A three-part questionnaire that covered the environment of the therapy institution (7 questions), the programs provided by the Speech-Language Pathologist (7 questions) and the degree of satisfaction and the demand for therapy education (7 questions) was used. The study results showed, in the area of the institution environment for therapy education, that the degree of satisfaction was highest for Social Welfare Center users due to the therapy costs. The level of satisfaction then decreased in the order of private clinic users and general hospital users. However, in the area of education programs provided by Speech-Language Pathologists, it was highest for the users of general hospitals due to the proper contents of the programs and consulting service. The satisfaction level then decreased in the order of private clinic users and Social Welfare Center users. Regarding the level of satisfaction with therapy education and related demand, the degree of satisfaction with language therapy and all therapy education services was generally satisfactory. After the language therapy, the children showed considerable improvement in their living skills (60% of survey respondents) and psychological stability (stress reduction, 30% of the total survey respondents). Regarding the future demand for therapy education, the degree of demand was high for the individual and group language therapy education service. In summary, the results of this study uncovered a number of problems related to services provided by language therapy education institutions and suggested various implications that Speech-Language Pathologists and relevant professionals should endeavor to use so as to enhance the satisfaction level of therapy education for autistic children.

The anatomy of the voice is not limited to the region of the larynx. Practically all body systems affect the voice. The larynx receives the greatest attention because it is the most sensitive and expressive component of the vocal mechanism, but anatomic interactions throughout the singer's body must be considered in making the singing voice. The physiology of voice production is exceedingly complex. The voice requires interactions among the power source, the oscillator, and the resonator. The review of functional anatomy and physiology in vocal technique would provide information on the terminology, components, and workings of the voice to permit an understanding of practical, every clinical problems and their solutions. The otolaryngologist, speech language pathologist, singing or acting teacher, singer, and actor would have benefit greatly from more extensive study of voice science.
