Isometric exercises that ease vocal production and strengthen laryngeal muscles are therapeutic for strains, throat lesions and other voice disorders, according to the Greater Baltimore Medical Center. Examples of voice therapy exercises include lip trills, gliding, and sustaining musical notes.
A healthy vocal warm-up improves speech and minimizes the risk of throat injury, notes the New York Eye and Ear Infirmary of Mount Sinai. Lip trills release lip tension while connecting breath and speech. Gliding up and down an octave range stretches vocal folds to enhance voice production. A physician or physical therapist can determine appropriate options for specific conditions.
