Hitting a wall with listening comprehension - I can read, but can't hear the word boundaries.

I’m an intermediate learner and I can read Zulu news articles reasonably well, but when I listen to native speakers, everything just blends into one long stream of sound. I suspect it’s because of how the vowels merge during fast speech. Does anyone have advice on how to improve this? I’m considering using Chickytutor.com to have the AI generate specific listening drills at varying speeds, but I’m open to other methods.
