摘要： 目的探讨语前聋儿童人工耳蜗植入术后元音声调的发声特点。方法8 例语前聋人工耳蜗植入儿童(聋儿组)和8 例同年龄组(3~4 岁)听力正常儿童(正常组)，在语训教师(音量控制在60~70 dBSPL)带领下朗读四声状态下的元音/a/、/o/、/e/、/i/、/u/、/ü/。对语音录音采样，采用Praat 语音分析软件提取共振峰(F1、F2)及音长。结果聋儿组元音四声错误率高于正常组，但两组儿童四声发音的难易程度一致。与正常组比较，聋儿组阳平/e/的F1，/i/和/u/的F2 存在显著性差异(P<0.05)；上声/e/的F2 存在显著性差异(P<0.05)；上声/o/、/e/和/ü/的音长存在显著性差异(P<0.05)。结论人工耳蜗植入儿童声调习得难度更大。共振峰、音长测试可为口型和舌位的训练提供参考。

Abstract: Objective To observe the pronunciation characteristics of vowels' tone in prelingual hearing-impaired children accepted cochlear implant (CI). Methods 8 prelingual hearing-impaired children accepted CI aged 3~4 years (group CI) and 8 normal-hearing children (group NH) with the same age were asked to pronounce the vowels of /a/, /o/, /e/, /i/, /u/, and /ü/ in four tones with the direction of speech training teacher. The sounds were recorded and analyzed with Praat software extract Formants (F1, F2) and duration of the sounds. Results The error of vowels in four tones was more in group CI than in group NH, but difficult level was almost the same between groups. There was significant difference in the F1 of /e/, F2 of /i/ and /u/ in tone 2, F2 of /e/ and duration of /o/, /e/, and /ü/ in tone 3 between groups (P<0.05). Conclusion Pronouncing the four tones of vowels is more difficult for the hearing-impaired children. For vowels articulation training,it is important to focus on the mouth and breath training.
