摘要

聽障兒童因為在聽覺反應能力較為不足，正確地掌握聲調對他們可能是比較困難的。在本研究中，以一對雙胞胎為研究對象。一位是聽障且植入人工耳的男孩，另一位是聽常的女孩。本研究將聽常聽障小朋友的聲調長度，以及聲調斜率做細部分析。結果顯示聽常小朋友比聽障小朋友的聲調持續時間還長，再者，聽障小朋友的聲調斜率比聽常小朋友的還平緩，沒有明顯的高低變化走向。

Hearing-impaired children have a hard time mastering tones precisely for lacking sufficient auditory feedback. A pair of fraternal twins participated in this study. One is a hearing-impaired boy, and the other is a normal hearing girl. Tone duration and slope of tones of these two children were measured. Results show that mean tone duration in the normal hearing child is longer than in the hearing-impaired child. Moreover, tone slops in the hearing-impaired child are flatter and less distinctive than in the hearing-normal child.
