I have a similar method if anyone wants to try it out. Five-six months ago, I couldn't say my name for the life of me. It was frustrating as hell 'cause you look like an idiot when you can't even say your own name. I'm pretty sure you guys know what I'm talking about. Anyway what I did was I started calling random numbers and asking for someone with MY name. For example, let's say your name is Bob and you block horribly at it. So what you do is call a random number and ask "Hello, can I speak with Bob?" or "Hey, I'm Bob, is ___ there?". Basically, say anything that involves saying your name. Of course you're going to stutter at first, but slowly you'll start getting used to saying your name in real-world situations. It'll take months but it'll work. Atleast it did for me. Now I can say my name in almost any situations and knowing that you'll be able to say your name if asked for, really takes a huge load off your chest and helps you in your other speech endeavors too..
