I'm not sure about imitation, I've never heard that one before. Maybe someone else can chime in on that. In response to your comment down below, I'm a bartender with a full blown stutter and I get by just fine. Some people probably think it's wierd but that's out of my control. Speech therapy is always an option if you think it's out of control. This sub is also great for support and story sharing if you're feeling down. You're going to be okay!
