|Condition or disease||Intervention/treatment||Phase|
|Essential Voice Tremor Vocal Tremor Voice Tremor Essential Tremor of Voice||Drug: Octanoic acid Drug: Placebo pill||Phase 1 Phase 2|
- Essential tremor of the voice produces regular shaking and hoarseness in the voice, making it difficult speech difficult to understand
- Several previous studies have found that octanoic acid and octanol, which are related to alcohol, can improve tremor in some people without producing many side effects and without producing intoxication
- Researchers are interested in determining whether octanoic acid can improve tremor that affects the voice
- To determine the effects of octanoic voice using voice recordings and listener ratings of voice
- To determine the effects of octanoic acid on level of voice disability experienced by people with essential voice tremor

- Pre- to post-treatment change in the acoustic characteristics of voice tremor [ Time Frame: Up to 1 year ]Voice recordings will be used to measure the degree of tremor in the voice. Degree of change from pre- to post-treatment will be compared for the octanoic acid and placebo conditions.
- Pre- to post-treatment change in the auditory-perceptual characteristics of voice tremor [ Time Frame: Up to 3 years ]Listeners will rate the voice from comparisons of recordings before and after each condition. Degree of change from pre- to post-treatment will be compared for the octanoic acid and placebo conditions.
