Idea replies — A bored evening turned into a multilingual AI phone agent. Now what?

What about making it a language practice hotline? Someone learning French or German could call and have a five-minute conversation about a random topic, with the agent adjusting its vocabulary to their level. Unlike most language apps, they'd actually have to speak and react in real time. You could even give callers a new challenge every day. Have you tested how it handles people who speak a language badly?
