I think this applies to everyone, but in my specific case my issue is that I talk with like my "head voice," I think because I'm just inside often but it also helps me stutter less, sort of related to gentle/easy onset I learned in speech therapy but it's easier to do if you're talking softly all the time too. my point kinda was if struggle with that sometimes and u haven't tried already u should lay down on your back and try talking, it makes it easier to activate your chest voice and it's actually noticeably less effort speaking, but when I do this I generally stutter more frequently. it's a hit and miss lol. there are times where I'm literally talking as loud as I possibly can in my head voice and STILL people can't hear me, or like I'm talking louder than I think is fit for the environment and yeah same result lolol
