I was able to overcome fear of public speaking by improving my physical technique, breathe with the goal of keeping the diaphragm full similar to how a bagpipe keeps its airbag full and lets air out to produce sound. Working on my pronunciation so that it is easily heard. Stress the first syllable of words. Stress the t sound. Soften the r in the middle and end of words. My favorite tongue twister is “After crossing the Sahara we found a bar in the bazaar”. Before a big speech I get myself hydrated four hours before. Good luck.
