The purpose of this study was to investigate the effects of stuttering severity on articulation rate measured from different types of utterances in preschool children who stutter. Participants were 40 boys who stutter (CWS) and age-matched 10 boys who do not stutter (CWNS). CWS were sub-grouped based on the severity of their stuttering: 15 mild, 13 moderate, and 12 severe. Utterances were categorized as "overall utterance" including all utterances that children spoke and "fluent utterance" which did not contain any disfluencies. Utterances containing abnormal disfluencies were categorized as "SLD utterance" for CWS. The results revealed no significant difference among groups in any type of utterance. There were significant positive correlations in articulation rates between utterance types. Stuttering severity was not a factor for characterizing the articulation rate of each type of utterance. Also, current findings suggest that articulation rate may not predict speech motor control ability in preschool CWS.

The purpose of this study is to prepare the basis for a more objective evaluation of oral fluency by analyzing Korean native speaker's utterance. Traditionally, fluency evaluation tended to rely on the evaluators' experience and subjective idea. Therefore, there has been a need of setting the evaluation standard in numeric form that is easily measurable. In this study, I will analyze Korean native speaker's utterance in focus of pause. Total number of 875 pauses were extracted from the 21st Century Sejong Korean spoken corpus, and the elements before and after the pauses were annotated. From the analysis results, the pauses were divided between fluent pauses and influent pauses. If the length of fluent pauses do not exceed reasonable length of pause for native Korean speakers, there was no point reduction. On the other hand, if the influent pauses are made more frequently than the native Korean speakers, then it is subject to point reduction.

Focal parts of utterance can be determined by new/contrastive information, a focus particle, a contrastive topic marker, or a nominative case marker in Busan Korean. Among these factors, new or contrastive information is the most important element in determining the intonational nucleus of an utterance. However, unlike Seoul Korean, when a focus particle, a topic marker, or a case marker contributes to the placement of the most prominent peak of an utterance, the peak is on the noun to which they are attached. Moreover, the case marker-ga shows more prominent pitch on the preceding noun than the noun followed by the topic marker-nun when-ga is used as emphatic or contrastive. This is one of the major problems for Busan Korean users in commanding natural and fluent Seoul Korean intonation even if they use standard written form of Seoul Korean in their speech.

Melody intonation therepy (MIT) is to improve the linguistic aspects of the verbal utterance for aphasic patients utilizing the intact right brain. It is applied to the aphasic patients with good comprehension, poor fluency, and little available speech are thought to be ideal candidates. The purpose of the study was to investigate the effects of Korean Melody intonation therapy (kMIT) in patients with non-fluent aphasia. Five male non-fluent aphasic patients were participated in this study. Average ages were 49.9 years old. Each therapy took 45-50minutes once a week for six months. Aphasic Screen lest (RISS) was used to assess language parameter such as Auditory comprehension, oral expression, reading, writing and calculation ability before and after kMIT. Mean of Length Utterance, verbal intelligibility and articulation disorder were assessed also. Computerized Speech Lab was used to assess the acoustic characteristics of aphasic patients before and after kMIT. The results are as follows : 1) Auditory comprehension, oral expression, reading, writing and calculation ability of the subjects increased after UH'. However, only oral expression showed significant difference (p<0.05). 2) Mean of Length Utterance of five patients generally increased after Un. 3) After kMIT, verbal intelligibility increased and showed significant difference (p<0.05). 4) Misarticulation rate generally decreased after m. 5) Voice Onset Time of the alveolar lenis /t/ and velar lenis /k/ gradually decreased after kMIT. 6) However, intonation pattern were increased gradually in yes'no question after kMIT.

English is one of the stress-timed languages and has much more dynamic rhythm, stress and the tendency toward the isochronism of stressed syllables. It goes with various English utterance restructuring, irrespective of the pauses by syntactic boundaries, and post-lexically phonological phenomena. Specifically in the real speech acts, the natural utterances of fluent speakers or the broadcasting speech cause much more various English restructuring and phonological phenomena. This has been an obstacle for students in speaking fluent English and understanding normal speech. Therefore, this study tried to focus the most problematic factor in English speaking and listening difficulty on English restructuring and post-lexically phonological phenomena caused by stress-timed rhythm and, second, to point out the importance of teaching English rhythm bearing that in mind.

The limited capacity model has been used to explain linguistic interactions and trade-offs that occur in children's speech. The purpose of the present investigation is to explore the interrelationship of MLU (as an index of syntactic development) and fluency in the spontaneous speech of normal children. Twenty normal children's (ten girls and ten boys, aged 36-48 months) spontaneous speech samples were obtained during free-play interactions with their mothers or other adults. The results indicated that the MLU of disfluent utterances were significantly longer than that of fluent utterances. Also, disfluencies occurred more frequently in longer utterances than in shorter utterances. In addition, the utterances where disfluencies occurred more than 2 times were longer than those where disfluencies occurred once. These results imply that the increase of MLU appear to affect not only the occurrence of disfluent utterances, but also the number of disfluencies within the utterances. In other' words, these findings show that there are trade-off effects between MLU and fluency. This is discussed within a limited capacity framework.
