Vocal exercises are activities designed to improve the strength, flexibility, and control of the voice. They often include techniques such as humming, lip trills, and scales, which help warm up the vocal cords and enhance vocal range. These exercises are commonly used by singers, actors, and public speakers to prepare their voices for performance or speaking engagements. Regular practice of vocal exercises can lead to better breath control, clearer articulation, and increased vocal stamina. They can also help prevent strain or injury to the voice, making them an essential part of vocal training for anyone who relies on their voice professionally or recreationally.
