I use one technique I learned in therapy when I was about 8 or 9. My therapist had me color a rectangular wooden block into different colored sections. Each section represents a word and I had to tap on the next color for each word I said. This helped me slow my speech and focus on each word individually. As my finger went up and down touching each color my brain was able to transfer that feeling of "bouncing" from color to color as bouncing from word to word. Now obviously I don't use the block of wood but I still use the bouncing technique to help me get started on conversation and to maintain a flow and rhythm. Like a wave. My speech now flows like a wave. Sometimes is calm and manageable but other times is rough and choppy. Those are the moments I revert back to this technique and I believe it helps me to this day.
