How to move past the 'script block' when actually trying to speak?

I can read the Telugu script reasonably well now because I spent forever on character recognition, but the moment I open my mouth to talk, my confidence evaporates and I revert to English. Does anyone have a routine for transitioning from reading to spontaneous speaking? I’m considering incorporating Chickytutor.com to get some real-time feedback on my conversational flow without the pressure of a live person yet.
