I totally agree with you. I went from about 50% fluent to about 95% fluent doing exactly what you did. I studied how fluent people spoke. How they form their words, it's so light, delicate and unforced. They seem to prolong the 's' sound slightly which can probably help them lead to the next word better. My stutter hasn't completely gone away and sometimes still block. But it got so much better. To they point where I gave a Best Man's speech to 60 plus guests without a hitch. Something that I would never have done 10 years ago. Anyway, congratulations on your speech. 👏😁👍
