I liked this a lot. I'm in the process of moving to Italy and am deep in learning Italian. I loved the different speeds and accents from the speakers.
Every video is transcribed to get much better transcripts than the closed captions. I filter on high quality transcripts, and afterwards a LLM selects only plausible segments for the exercises. This seems to work well for quality control and seems to be reliable enough for these short exercises.
Would love your thoughts!
