In May of this year British born singer-songwriter Sean BW Parker gave a talk about stuttering for a TEDx gathering that took place in Istanbul, Turkey. A stutterer all his life, when he was young Sean changed his name from "Ben" to "Sean" because it was easier to say.
In his talk, he gives his own perspectives on the problem of stuttering, what causes it and the best ways to cope with it. You can listen to his speech here.
TEDx talks are an offshoot of the TED talks, organized by smaller communities.
