practicing speaking with yourself??

okay so I don't have anyone to talk to because my FIRST priority is just trying to speak. I tried doing that slanting thing... wait no SHADOWING. where you repeat the anime audio. but my dog just stares at me like i have a tail?? actually she is black and cute but anyway i forgot what the question was. how do you practice alone? is there even any value to it? i enlist in this daily but get so tired
