Nicely done, really cool mechanics and a really interesting take on a memory game. Only major issue I encountered was that it was forced fullscreen and I only have a 21:9 monitor, so some of the UI elements went out of frame.
I agree with the idea of shortening time between syllables, or cancelling a phrase in case you start with the wrong one. I often found myself slowly going through each syllable to remember which was where.
Overall, really well done!
