Fluentjoy AI Conversation Tutor

An agentic AI tutor for English conversation practice, shipped to production on the Fluentjoy iOS app.

The system runs dynamic role-play scenarios end-to-end: it picks a persona, drives the dialogue, scores pronunciation in real time, and coaches responses in context — all tuned to the learner’s current level.

Behind the experience sits a multi-cloud backend on AWS with auxiliary inference paths through Azure and GCP, and a model orchestration layer that routes between OpenAI and pronunciation-scoring services co-designed with the speech team.
