The best cure for a stammerer and indeed for anyone interested in public speaking is to first and foremost calm your nerves. This is because stage fright can even induce stammering even when it is not a disability to the speaker.

Next is to speak in measured tones, count your words so to speak. In an attempt to talk very fast, your words will tumble over themselves making your disability worse. This will of course affect your self confidence. On the other hand, if you count your words, you will find once you have successfully gotten out of the first sentence the rest would be easy. It is never polite to make it obvious talking about others in public.
