During lockdown I lived alone and wasn’t having much interaction, it was also one of my worst fluency periods in years. It was never a serious enterprise but just started live streaming my ps4 direct to YouTube and chatting in to the mic for the speech practice. It did wonders for my fluency and confidence. Weirdly watching my videos you may never know I stutter, I think it kicks in to that presentation mode some of us (though not all) experience where if you are on stage giving a performance it stops being so much of an issue but we might struggle with day to day things. Also gained a handful of subscribers and viewers which wasn’t bad for the minimal production quality. If you are not sure about the speaking part, why not just practice on an alternative channel for a bit then go on your main one when you are ready?
