To all those suffering from stuttering, stammering or other related speech impediments, take heart! I endured this socially-debilitating condition for years. Nothing helped, including a range of speech therapies. However, I decided to join a public speaking club - Rostrum here in Australia - and the overall improvement to my speech was just staggering. Stuttering is no longer the bane of my life! I can take part [very comfortably] in one-on-one and/or group conversations; plus address small or large groups of people, without risking heart seizure! If you have tried everthing else with little or no success, why not try public speaking. It may not work for everyone, but what have you got to lose! Good luck.
