Is there a script on roblox that can remove speech

noo im pretty sure i would of heard of it by now but u can make some kind of screen gui that u can type in scripts im guessing its just for the scripts but it doesnt matter anyway cuz it worked even though i don't kknow it i know that there is one.

one time i went into my place and hit tools and then settings i checked it out a bit and somewhere in it i changed how long my bubble chat thing above my head stayed there and im sure u can change the regular chat that's in the corner like how lone ur text stays up there and this isn't just for ur place u have it every where... i did something wierd with it where it outlined everything and another where it made reflectant things be more real looking it was cool.
