Apraxia of speech(=AOS) is, together with aphasia and dysarthria, one of nuero-language disorders. Many AOS patients have problems with determining the right place of articulation and systematically conducting sequential movements when they speak, although they have no physical problems with their articulators.
Since AOS usually comes together with aphasia, it is hard to find out its own symptoms, and thus many earlier studies have been devoted to figuring out its characteristics with reference to apraxic patients' speech errors. Scholars have been interested in such questions as whether specific segments determine specific errors, whether main error types are distortion or substitution, and so on. These studies, however, are problematic in two respects: first, the main focus of most previous studies is apraxic patients' performance with monosyllables, although they display more difficulties in pronouncing multisyllables than monosyllables; and secondly, characteristics of the disease may differ from language to language, but most earlier works are about English speaking patients.
With these problems in mind, this analyses and compares two groups of Korean subjects, normal and AOS, using an experiment with two-syllable structures, namely V-CV structures, in four results: 1) kinds of errors (distortion/substitution) according to the place of articulation, 2) the time rate of each syllable, 3) VOTs of stop sounds, and 4) F1 and F2 of vowels. By comparing the differences of these phonetic characteristics between the two groups, this thesis aims to clarify the characteristics of AOS, on the basis of Korean-speaking patients' performances, and to provide fundamental criteria for diagnosing and evaluating the disease.
