AB  - OBJECTIVE: To discuss the voice change and acoustic character of essential voice 
      tremor. METHOD: Observations and acoustic studies were performed about clinical 
      manifestations and voice of 18 patients with essential voice tremor. RESULT: In 
      18 patients with essential voice tremor, female accounts for 72% (13/18 cases). 
      The mean age at tremor onset was 57 years old . And 8900 of them had no 
      neurologic abnormalities. The clinical manifestation includes voice tremor, 
      dysphonia, even frequent voice interruption. The laryngeal body happens to 
      regular tremor in automatically. Bilateral vocal cords, ventricular cords and 
      arytenoid cartilages also tremble regularly open and closed, together with the 
      tremor of voice-producing organs(soft palate, tongue and lateral pharyngeal 
      wall). The frequency of voice tremor is 4-6 Hz. The acoustic analysis 
      characteristics of voice is the obvious increasing of Shimmer, presenting the 
      specific change of the parameters such as soft phonation index (SPI), degree of 
      voiceless (DUV), degree of voice breaks (DVB), FO tremor intensity index (FTRI) 
      and Amplitude Tremor Intensity Index (ATRI). CONCLUSION: The voice change of 
      essential voice tremor is a kind of regular tremor with low frequency. For the 
      severe patients, it shows dysphonia and frequent voice interruption.
