speak louder, clearer and more slowly

I still have to pay attention to my every day talk and I think I will never stop mumbling and talking too fast,
but
today
I had a welcome meeting with about 20 customers, in a loud lobby area, and my voice was loud and clear and I articulated most of the words perfectly. It felt great. I can do this if I just try. :)

clarity, check
slowness, check

need to work on talking more loud so that people don’t need to say “what?” or “excuse me?” every time i open my mouth.
