Objective: This study identifies the most suitable syllable for laryngeal diadochokinesis (LDDK) in Mandarin speakers. Methods: One hundred and ten Mandarin speakers aged 18-83 were used in the study. LDDK was assessed using quick repetitions of /?e/, /?i/, /?a/, /he/, /ha/ and /hi/. The observation index included the average rate (syllable/s) and regularity (%jitter). Results: In the various age groups, there was no significant difference in LDDK rate and regularity of adducted syllables (P > 0.05), and only the regularity of /?i/ is significantly different between aged 18-40 and 41-64 (P = 0.040). When vocal fold adduction was compared between various syllables, there was no significant difference in LDDK rate and regularity (P > 0.05). In various age groups, the LDDK rate of abduction syllables is different (P < 0.05) compared with the LDDK regularity of abduction syllables (P > 0.05). In various abduction syllables, there is no difference in LDDK rate (P > 0.05); however, /ha/ and /hi/ have significant differences in LDDK regularity (P = 0.007). Conclusion: According to the preliminary data, /?a/ and /ha/ can be used as suitable indicators to analyse the coordination ability of the laryngeal movement of Mandarin speakers.
