摘要

許多致力於聽障孩童語言發展的專家學者指出，早期人工電子耳植入有助於聽障孩童的語言發展。本篇研究旨在觀察一名早期植入人工電子耳孩童的聲調發展，並與其聽力正常的異卵雙胞胎妹妹的發展做比較。語料採集自4個月大至34個月大，每兩個星期進行一次蒐集，錄音場所設於孩童家中，以孩童之間的互動或與媽媽的互動爲主。本篇研究報告對18個月大至24個月大的語料進行分析研究，其結果指出該名聽障孩童的第四聲出現率最高，並且一聲與四聲的正確率較其他聲調高。雖然從生理年齡的觀點來看，該名孩童的發展不如雙胞胎妹妹，若是以聽齡做爲考量，他的表現則是適齡發展。此外，該名聽障孩童亦在基頻最大最小值差上表現出成長變化。

Specialists working in the field of the language development of hearing-impaired children underline the importance of early cochlear implantation. This study probed tone acquisition in a hearing-impaired child with early implantation, and compared him with his hearing-normal fraternal twin sister. They were observed at home, once every 2 weeks, from the age of 4 months to 34 months. The speech data was recorded with Sony DAT recorders and consisted mainly of natural daily interactions with each other or their mother. This current study reports the observation from 18 to 24 months. The results indicated that the hearing-impaired child produced the high falling tone with the most precision, and correctly produced the high level tone and the high falling tone more frequently than the other tones. Although the hearingimpaired child did not perform as well as his hearing-normal twin sister at the same age, if his hearing age was taken into account, his tone development was age appropriate. Moreover, the hearing-impaired child also showed improvement in the difference between maximum and minimum of fundamental frequencies.
