"Good morning , my name is ___________ and I'll be your trainer for today. I do have a speech impediment, I have a stutter so if I have a block please give me 8 hours and hopefully it will come out (insert audience laugh here) but if it doesn't , help me to help you to help me because I believe that Team Work Makes The Dream Work (insert audience inspiration claps). So let's get started". This ice breaker let's everyone know in the audience of what I have and it relieves tension/anxiety from them and makes the training more enjoyable (plus the huge applause 👏 at the end is always nice) Also, I've had a few audience members help me through the block (and they knew what I could not say because it was on the 10x20 ft PowerPoint screen behind me) and I thanked them and moved on.
