I don't try and avoid words. When I feel like I'll stutter on something I will try and maybe slow down and try and get through it or maybe rush through it and hope for the best. I've been told by a few people when talking about my health and stutter that they think I breathe strange and people do tend to mention that they hold their breathe when speaking and they tend to stutter due to that or they don't speak on an exhale. Idk there seem to be too many variables per person to find out the cause and a possible solution to it. I'll check the article and hope it can work for me too.
