R49: Voice disturbances

Voice disturbances, also known as dysphonia, is a group of conditions that affect the quality, pitch, volume, or speed of your speech. These conditions can be caused by a variety of factors including vocal cord damage, neurological disorders, psychological issues, and more. You might notice changes in your voice such as hoarseness, breathiness, or even loss of voice. Sometimes, you may also experience discomfort or a strain in your throat while talking. The progress of these conditions can vary widely; some voice disturbances may resolve on their own while others might get worse over time and affect your ability to communicate effectively. These conditions specifically impact the muscles and nerves of the larynx or voice box, a part of your respiratory system.
