I have a lot of presentations on zoom these days and i'm so scared !! So i'm thinking about pre recording my own voice and lipsync during presentations. I know it's cowardice but i'm desperate. Update : Thank you all for the advices !! I decided not to use my pre recording voice and did the presentation by myself. I stuttered really bad for the first half and i can't even answered question properly. Ngl i feel embarassed and frustated, but doing the presentation by myself feels like a small achievement.
