Voice disorders refer to conditions that affect the quality, pitch, volume, or duration of a person's voice. These disorders can result from various factors, including overuse of the voice, medical conditions, or structural abnormalities in the vocal cords. Common symptoms include hoarseness, breathiness, or a complete loss of voice, known as aphonia. Treatment for voice disorders often involves speech therapy, where a speech-language pathologist helps individuals learn proper voice techniques and exercises. In some cases, medical intervention may be necessary, such as surgery to correct structural issues. Early diagnosis and intervention can significantly improve outcomes for those affected.
