This study examined the effects of non-word versus real word, age, and gender on oral-DDK rates among healthy Malaysian-Mandarin speakers. Comparison between non-word of Malaysian-Mandarin and Hebrew speakers was examined.
One-hundred and seventeen speakers (18-83 years old, 46% men) were audio-recorded while performing non-word (repetition of "pataka") and real-word oral-DDK tasks ("butter cake" and " ([pa4ta1kan4])"). The number of syllables produced in 8 seconds was counted from the audio recording to derive the oral-DDK rates. A MANOVA was conducted to compare the rates between age groups (young = 18-40 years, = 56; middle = 41-60 years, = 39; older = 61-83 years, = 22) and gender. In a second analysis, "pataka" results were compared between this study and previous findings with Hebrew speakers.
No gender effects were found. However, rates significantly decreased with age ( < 0.001). Repetition of real words was faster than that of non-words - English words (5.55 ± 1.19 syllables/s) > non-words (5.29 ± 1.23) > Mandarin words (4.91 ± 1.13). Malaysian-Mandarin speakers performed slower than Hebrew speakers on "pataka" task.
Aging has a large impact on oromotor functions, indicating that speech-language pathologists should consider using age-adjusted norms.
本研究考察了非单词与真实单词、年龄和性别对健康的马来西亚华语使用者口腔-双音节重复率的影响。同时考察了马来西亚华语使用者与希伯来语使用者非单词重复情况的比较。
对117名使用者（年龄在18 - 83岁之间，男性占46%）进行录音，他们分别执行非单词（重复“pataka”）和真实单词口腔-双音节重复任务（“butter cake”和“([pa4ta1kan4])”）。从录音中统计8秒内产生的音节数量，以得出口腔-双音节重复率。进行多变量方差分析以比较不同年龄组（青年组 = 18 - 40岁，n = 56；中年组 = 41 - 60岁，n = 39；老年组 = 61 - 83岁，n = 22）和不同性别之间的重复率。在第二项分析中，将本研究中“pataka”的结果与之前希伯来语使用者的研究结果进行比较。
未发现性别影响。然而，重复率随年龄显著下降（p < 0.001）。真实单词的重复速度比非单词快——英语单词（5.55 ± 1.19个音节/秒）> 非单词（5.29 ± 1.23）> 华语单词（4.91 ± 1.13）。在“pataka”任务中，马来西亚华语使用者的表现比希伯来语使用者慢。
衰老对口腔运动功能有很大影响，这表明言语语言病理学家应考虑使用根据年龄调整的常模。
