Turn off, dictation auto correction

Does anyone know how to turn off all of the auto correction iOS does during dictation? It’s becoming far more a hindrance than a convenience. I don’t need iOS to correct me. The auto comma feature is the worst. But I’m also tired of the wavy red lines and the wavy blue lines under words. I’m making more corrections to the auto correction than I am to my own words. It has become ridiculous. I’ll make corrections myself.
