But despite being a native English speaker, they couldn’t be bothered to actually write the article themselves. What’s the point of learning a language - any language - if you’re not even going to use your own words like an adult?
I used voice mode on ChatGPT to learn the tones for mandarin, and general vocab and sentence structure while for Japanese it helped me expand proper sentence structure greatly.
It sounds silly, but it helped reenforce a base structure that is helpful and having it confirmed by a tutor was nice. Best is I can really do it whenever. What op posted does sound next stage, and I can imagine it’d be a viable platform.
I don’t suggest notebookllm to make an audiobook, I tried and it was the most dryest speech I ever heard. It did sound convincing enough if you were to do a podcast for it and that is what it does.. but it was completely horrid for learning but maybe that’s just me.
This just isn't a reliable source, even putting aside trying to measure language proficiency through memorising grammar.
Watch movies and listen to people if you want grammar to stick. Languages are living things. Not something you practice in a bubble with Anki and Duolingo.
