No: Unless you are taking anabolic steroid this shouldn't affect your voice. As for your stamina, it is partly genetically determined and partly related to your health and physical condition. There is no easy way to improve strength without exercising. If stamina is the issue, be sure to check with your doctor re. your cardiopulmonary status.
