Listeners' perception toward stuttering has been considered an important factor to the diagnosis and treatment of stuttering. This study intended to examine perceptual differences between speech language pathologists and laypeople toward children and adults with stuttering. A Total of 102 subjects were surveyed. speech language pathologists' perception was more stereotypical than that of laypeople. laypeople perceived adults and children with no significant differences but, clinicians viewed adults more stereotypically. speech language pathologists were not influenced by experiencer, but experienced laypeople perceived children more negatively although people who have stuttering family members showed a less stereotypically. item analysis revealed that both groups showed different perspectives between adults and children with stuttering.

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.

This study examined the acoustic characteristics of Korean alveolar fricatives of normal children. Developing children aged 3 and 7, typically produced 2 types of nonsense syllables containing alveolar fricative /sV/ and /VsV/ sequences where V was any one of three corner vowels (/i, a, and u/). Stimuli containing the speech materials used in a production experiment were presented randomly to 12 speech language pathologists (SLPs) for a perception test. The SLPs responded by selecting one of seven alternative sounds. Acoustic measures such as duration of frication noise, normalized intensity, skewness, and center of gravity were examined. There was significant difference in acoustic measures when comparing vowels. Comparison of syllable structures indicated statistically significant differences in duration of frication noise and normalized intensity. Acoustic parameters could account for the perceptual data. Relating the acoustic and perception data by means of logistic regression suggests that duration of frication noise and normalized intensity are the primary cues to perceiving Korean fricatives.

This study examined the affective prosodic characteristics observed from the children with cochlear implant (CI, hereafter) and normal hearing (NH, hereafter) along with listener's perception on them. Speech samples were acquired from 15 normal and 15 CI children. 8 SLPs(Speech Language Pathologists) perceptually evaluated affective types using Praat's ExperimentMFC. When it comes to the acoustic results, there were statistically meaningful differences between 2 groups in affective types [joy (discriminated by intensity deviation), anger (by intensity-related variables dominantly and duration-related variables partly), and sadness (by all aspects of prosodic variables)]. CI's data are much more louder when expressing joy, louder and slower when expressing anger, and higher, louder, and slower when it comes to sadness than those of NH. The listeners showed much higher correlation when evaluating normal children than CI group(p<.001). Chi-square results revealed that listeners did not show coherence at CI's utterance, but did at those of NH's (CI(p<.01), normal(p=.48)). When CI utterances were discriminated into 3 emotional types by DA(Discriminant Analysis) using 8 acoustic variables, speed related variables such as articulation rate took primary role.
