| Outline of Final Research Achievements |
This study provides a framework which shows how fluency disorders are produced. For the type of disfluency where the subject focuses on repetitions of the constituents in a word, the triggers of the repetitions are examined according to evidence from the statistic studies whose speech samples are about 21000 produced by 600 speakers. The triggers are phonetic transitions, prosodic units,and word initial positions. Each trigger corresponds to a particular symptom. Based on Optimality Theory, trigger rankings are caluculated for stutterers and non-stutterers, for each language. Non-stutterers' disfluencies are brought about by a phonetic taransition between sonorants. They break OCP. Stuttering is caused by anaother phonetic transition between sonorants and obstruents. It stumbles on a hard phonetic transition. Prosodic units and word initial positions stay in the middle of the ranking. They form some inherent morphological styles of repetitions in each language.
