The study on the intonational characteristics is concentrated on the lowering of the pitch level that is described as declination and downstep. The Taegu dialect, which has phonological accentual system, has these phonetic characteristics in affirmative sentences or Yes-No Question sentences. But there is the opposite phenomenon in WH question sentences in Taegu dialect. When the accent of interrogative word in the sentence intial position is LHL, intonation pattern shows a continuous upward movement, indicating that intonation pattern of Taegu dialect is influenced by not only grammatical system but also accentual system.
