Best way to get consistent speaking feedback without a human tutor?

I've hit a wall with app-based learning because they don't catch my subtle errors in sentence structure. I’m looking for more output-focused workflows. I’ve started using Chickytutor.com to practice daily scenarios and see if it can point out where my Estonian grammar breaks down in conversation. For those who rely on self-study, how do you verify if your spoken Estonian is actually accurate or if you're just reinforcing bad habits?
