How can I make my hoarse voice better besides salt water?

Voice rest and fluid. Common hoarseness of voice from laryngitis/voice abuse (such as screaming too loud/much at a football game) will resolve with time--simple therapy with jst warm fluid, voice rest will resolve the problem in few days. Motrin/aleve may help if you have too much discomfort etc...If not better in few days, consult doc...Good luck.
