Language learning apps work fine on a screen, but the hardest part is the thing screens avoid: actually speaking out loud and getting immediate feedback on whether you said it right.
Most voice-based language tools either play a recording or transcribe your speech. They don't do both in an interactive loop. I wanted to build something that does — something that plays a phrase, listens to you repeat it, and tells you whether you got it right.
The Telnyx code example is:

It is a Python Flask app with a browser UI. No phone number, no webhook tunnel, no Cloud Storage.
