I'm not even sure this helps with speaking practice since it's just a test of whether what you said can be transcribed by Whisper, which is not at all a test of correct pronunciation. I just tried it with the most horrid, butchered accent I could muster, and it still worked...if I practiced for months on end like that, I'd end up in a very difficult place as a language learner.
My thinking is - I can have unstructured conversations with Advanced Voice Mode or in real life here in Sweden. What I'd really appreciate is a guided learning experience taking me up from intermediate/slightly above intermediate to fluent in the most efficient possible way (as opposed to just having us 'ramble' about random topics of my own choosing).
This is available for all proficiencies. It's just much harder to talk for hours in a new language as a beginner. It's usable but requires more effort.
Another thing is that the trial period seems incongruent. To me the structured curriculum is what I really want to _try_. I want to see what the planned lessons are like, how guided they are, etc. But the trial runs out and tries to make me pay right after the unstructured more all-over-the-place feeling introductory conversation, and I'm not prepared to pay at that point since I feel like I haven't gotten to evaluate the main part of the product at all. I would suggest leaving the trial unlocked to maybe the first three structured lessons of the learning plan. Let the user really experience what they'll be paying for.
* curriculum, completely customizable, with grammar, roleplay, topics, speaking speech, transcript, dictionary, corrections, etc
* prompting and AI models all chosen to be a better fit for multilingual, easy to understand, etc.
* the tutor actively tries to teach you, it's not an assistant
* integrated flashcards that go hand in hand with the speaking immersion
I tried following the modern Japanese track on Memrise and was appalled at how bad it is nowadays.
