Temporary recurrent voice disappearance

Temporary recurrent voice disappearance, also known as episodic aphonia, involves periods during which a person’s voice becomes very weak or completely absent. This condition usually occurs after prolonged speaking or vocal exertion, and the voice typically returns after a period of rest. In myasthenia gravis, this symptom arises due to the fluctuating weakness of the muscles involved in producing sound. Individuals notice that their voice starts strong but gradually fades to a whisper or becomes inaudible as they continue to speak. These episodes vary in frequency and severity, often triggered by factors such as fatigue, stress, or extended use of the vocal cords.
