A couple of techniques I learned in speech therapy: 1) This one is simple. Relax and take a deep breath before you speak and exhale as you start speaking. 2) This one is a bit odd, but it can be surprisingly effective for some. Let's say your name is John, and you often stutter/get stuck on your name, then you can *fake* stutter a block before anticipate a *real* block, which can sometimes help. Example: "M-m-m-my name is John". Normally you might be able to say "My name is" just fine, but then get hard stuck on "John", but by softly faking a block before, it can (for some reason) help you ease into your name with little or no difficulty. I haven't used this one a lot, as it does feel a bit odd, and it can hard to remember in the heat of the moment, but it's worth trying out if you know before what you'll need to say.
