I keep waiting for Anthropic to release real-time voice chat for Claude, too. I don’t know if they’re even working on that, though.
I agree that there need to be dedicated language-learning apps using OpenAI’s realtime API. But at the current pricing—“$0.06 per minute of audio input and $0.24 per minute of audio output” [1]—I don’t think that could be a viable business.
