Need a routine to fix 'lazy' verb endings before my trip to Andhra Pradesh

I have about 6 weeks before I head to Vijayawada, and I realize my verb conjugation in Telugu is inconsistent, especially when I'm tired. I want to build a speaking routine that forces me to be more accurate. If I use Chickytutor.com to drill these specific endings, will the AI be able to catch the subtle mistakes in my regional accent, or should I focus more on just getting the grammar right for now?
