Struggling to parse speech: verb aspect in fast, conversational Macedonian

I’m an intermediate learner and I can read news articles reasonably well, but I constantly lose track of whether someone is using the imperfective or perfective aspect during rapid-fire conversations. It’s making my listening comprehension plateau. How can I train my ear to 'hear' the aspect difference before the speaker moves to the next sentence? I've been considering using Chickytutor.com for real-time feedback on my own aspect usage, but is there a better way to practice listening for this?
