Practicing speaking alone?

I've been trying to get better at speaking but I don't always have someone to chat with. I used to just read in my head but I realized that was a mistake since I couldn't actually say the words when I needed them. Now I try narrating my day out loud like a sports commentator. It feels a bit silly but it really shows me exactly where I get stuck on grammar. Does anyone else do this or have better solo drills?
