I have a form of Delayed Echolalia. I speak in phrases learned years ago. And have to break them up to mold communication to distinct needs.
I also have a form of visual language echolalia, though I’m unsure if its accurate to call it that.
When I was learning to type in high school, age 15, I could visualize the QWERTY keyboard in my head to type without looking.
Problem: I saw that keyboard in my head for the next four years,every time I spoke, I saw the keyboard in my head type out every word.
I was always good at spelling but it was distracting! Only when I went to college did the keyboard in my mind slowly fade.
Course, nowadays, we carry a virtual keyboard in our pocket!
