Does anyone feel less “intelligent” because of they’re speech?

Does anyone feel less “intelligent” because of they’re speech? When I’m supposed to train someone at work, I sometimes get the feeling that the person I’m training might feel like I am a bad trainer based on how I speak. And that because I can’t speak fluently, I must not know the job well enough to teach them. I sometimes feel it would be easier if I could somehow type it all out for them and then I’d seem more “intelligent.” I know this is all false, and no one has ever had a negative thing to say while training (at least not to me anyway.) And I know that even though we have this disability, we are smart and more than capable of doing things! It’s just anxiety brain at it’s best. 😁🤦🏻‍♀️
