Hi Vikram, from my experience, whenever I have faced an uncomfortable speaking situation, I try to focus 100% on the Crutches. If I succeed, the next time I face the same or a similar situation, I find it much easier to avoid stutters. And after practicing for a while, I have found myself using the Crutches automatically.
It’s a matter of practice.
In any event, I’ve heard you speak several times at the Speechmasters Club meetings, and you sound great!
