To identify phonatory measures of vocal fold tremor, patients with benign essential tremor (BET) of the vocal fold folds were compared with normal controls and patients with phonatory tremor due to other neurological disorders. Measures included: the percent frequency and amplitude variation due to tremor, range, rate and regulatory of tremor. Patients with neurological disorders (including BET) had greater frequency and amplitude range and percent variation due to tremor, but no increase in jitter and shimmer. The acoustic measures which specifically reflected vocal fold tremor in BET were the range in frequency variation and the varaiation in linear trend in frequency and amplitude. Tremor rate did not differ between BET, other neurological disorders and normal voices, but the regularity of the tremor rate did.
