Language-learning app Speak published a technical writeup on its Live Tutor lessons powered by GPT-Live. The key architecture pairs low-latency decisions with the Live API: a lesson harness observes the ongoing conversation, manages its flow, and guides the learner in real time. The system decides when to intervene with corrections and how to deliver feedback without breaking conversational rhythm, enabling a highly responsive live AI tutor.
