Key Words Diabetes mellitus; Voice quality; Vowel; Voice diagnostics; Acoustic parameters; Glucose metabolism Summary Objective The objective of this study was to investigate if there are differences in acoustic parameters between diabetic patients and normal controls. Methods A prospective cross-sectional study was performed in 83 diabetic patients and 70 healthy controls. Voice parameters including fundamental frequency (F0), jitter, shimmer, amplitude perturbation quotient, noise-to-harmonic ratio, smoothed amplitude perturbation quotient, and relative average perturbation were analyzed using Computerized Speech Lab with the Multi-Dimensional Voice Program. Results F0 in female diabetic patients was significantly lower than controls (222.23 [plus or minus] 27.89 Hz versus 241.08 [plus or minus] 28.21 Hz, P Conclusions Voice fundamental frequency is lower in females with diabetes. However, voice fundamental frequency cannot adequately predict the presence of diabetes.
