Ask HN: Conversational AI to Learn a Language

Hi! I have a WIP of this over at https://talktrainer.app/ -- I just added Dutch to it.

It uses OpenAI's realtime API to simulate either a tutoring session (the speaker will revert to English to help you) or a first date or business meeting (the speaker will always speak the target language)

You can see the AI's transcriptions but not your own, limitation of the current OpenAI API but definitely something I can fix.

The prompts are like this: https://gist.github.com/jc4p/d8b9d121425ec191d62602d8720eeed... and the rest of it is a Nextjs app wrapped around the WebRTC connection.

I'm not fully in love with the app so I'd love any feedback or hearing if it works well for you -- It doesn't have a lot of features yet (including saving context) and if you bump into the time limit just open it up in incognito to keep going.

One modification I would suggest is to add a bit more to the initial prompt like:

"write as if you are a person from {{REGION}}. Modify your language to proficiency level {{PROFICIENCY_LEVEL}}"

that way I could for example, speak as if it's someone using Mexican Spanish vs Madrid Spanish vs Chilean Spanish, etc.

Secondly, you could include the user's speech transcribed as part of the conversation window

Amazing idea, do you think this should be a freeform text field the user can enter to add their own prompts to or should it be a checkbox/select on the homepage so the user can pick from a limited set?
