Is there any free speech therapy content online?

Is there any free speech therapy content online? I desperately need to start speech therapy again, but I can’t afford it right now. I’m unemployed, and there’s no adult SLPs that accept my insurance in my area. I know for speech therapy to be truly effective, you have to work 1-on-1 with a SLP, but has anyone come across any free speech therapy content that’s been helpful?
