Speech help

My daughter is still not saying any words. (If you saw the post awhile back about her having a lot of ear infections and she could talk before that and her tubes but doesn’t now) She will mimic any noise or sound I make but absolutely will not mimic words. How do i get her to start speaking?? Due to covid we can’t see a dr or get into a speech therapist and i just want to do something to help. I read to her, and I talk to her all day long but that doesn’t help. She literally says 0 words. But she understands what we say to her and things we tell her to do. She’s developmentally on track with everything except her talking
