Sorry but the approach is too naive and the tech isnt there yet.

You can't make up a couple of conversation topics and expect the LLMs to do the rest by just switching languages. People approach the same topics completely different in different languages. The app looks like someone picked a couple of topics and the rest is "just" ChatGPT advanced voice mode.

And the worst thing is that the LLMs in TTS do not sound native and cannot teach you pronounciation and learning to listen and understand (which is the whole point in having spoken conversation).

And the other way around, the STT will not notice pronounciation mistakes made by the student - so the app cannot tell you: oh, its pronounced like this.
