Reading the script is easy, but my brain freezes when I try to speak.

I’m a false beginner who spent months on Duolingo and can actually read the Kannada script quite well now. However, when I try to speak to my neighbor, my brain completely locks up trying to recall the correct verb ending. It's like I have the input down, but zero output speed. Does anyone else get this 'reading-writing vs. speaking' paralysis? How do you force yourself to speak without over-analyzing the grammar rules?
