Recognize when your voice is tired. Consider vocal training if you have to talk or sing loudly, or speak extensively for your vocation or avocation. Vocal endurance, like athletics, requires special skills. Hoarseness or breathiness may signal a voice disorder. If either symptom persists for more than two weeks, call a physician or speech-language pathologist.
Stress can lead to forceful voice production, resulting in possible tissue damage.
Relaxation techniques can improve your voice and allow you to speak more effectively and longer. Caffeine and alcohol dehydrate vocal folds, which can cause tissue damage. Drink plenty of water to combat their drying effect. For example, for every mug of coffee you ingest, drink at least one 8 oz. Some medications lead to dehydration of the vocal folds.
