If you don't mind me wo say like that, I'd say changing words is the dumbest strategy to avoid stutter, because not only will changin words be in vain in extremises like telling your name, telling your location, telling your phone number and etc., but also in essence changing words can't still get yourself rid of fears and anxieties of stutter, opposite to all of decent speech therapies' missions. Remember changin words is just an expedient only if you are ignorant of the essence of stutter and at a loss what to do. Avoidance Reduction is extremely crucial to migitate stutter, not to 'hide' it.
