中文摘要

現有電子耳國語（Mandarin）的聲調研究結果常包含三歲以下或電子耳經驗僅數月兒童的聲調表現。本研究以聽力室內的電腦化測驗評量12位6－15歲、電子耳經驗兩年以上、習語前失聰兒童的聲調指認和表達。實驗一聲調指認，由兒童在聲調刺激與不同聲調圖片搭配組成的12情境下，以二選一方式指認單音節語詞的聲調，但需兩次指認嘗試皆正確才計分。所有語詞皆以對話形式錄製。實驗二聲調表達，將錄自實驗一電子耳兒童的語詞，由評審以四選一指認方式評量其聲調。兒童聲調指認的團體得分為58％，低於文獻記載的67－73%，且2、4聲的指認受測驗情境影響，並以4聲搭配1、3聲圖片之得分別為最高（72％）和最低（30％）。兒童聲調表達的團體得分為67％，高於文獻記載的47－53％，且1、4聲得分（79％、71％）高於2、3聲（59％、59％），且聲調間的混淆模式各有不同。個人表現方面，指認和表達得分呈高度相關，且近半數兒童，雖有3－9年的電子耳經驗，仍有對聲調教學介入的特殊需求。
英文摘要

Previous studies of Mandarin tone performance by prelingually deafened cochlear implant (CI) users contained identification and production results from subjects aged below three years old or with only months of device experience. This study revisited this dual topic with twelve CI users, aged 7 to 15 years, at an average postoperative period of six years. In the identification experiment, participants completed a 2-Alternative Forced Choice (2AFC) picture identification task in which they identified the four Mandarin contrastive tones of 60 monosyllabic Chinese words under 12 picture-pairing conditions. All the words were pre-recorded in conversational styles. Scores were given only to words that were identified correctly in both trials. In the production experiment, the same 60 words used in the identification experiment were elicited and recorded from each of the above CI users and the tone of each word was judged by 20 normal hearing adults in a 4AFC identification task. The group mean identification score was 58%, compared to 67-73% as previously reported with a 50% response chance level. Identification of tones 2 and 4 was found to vary significantly with the picture-pairing condition. The group mean production score was 67%, compared to 47-53% as previously reported. Individual tone score rankings and tone confusion patterns were inconsistent with results from computerized investigations, while similar to those from a study using a 5-point evaluation that only tested school-aged subjects. The results suggest that tonal performance of the pediatric CI users may vary with the age range, CI experience and test reliability. Individual identification and production scores were highly correlated. The less than satisfactory performance levels in both measures also revealed special needs for auditory training even among the CI users with extended device experience.
