FRENCH AI CONVERSATION AGENT

Inspiration

Many language students hit a wall — they can study all they want, but without a native speaker to practice with, verbal fluency never comes. Existing AI tools that solve this sit behind paywalls. I built this software to make that practice free and accessible to everyone.

What it does

This software is a web-based AI conversation agent that simulates a video call in French. The student speaks, the AI listens, understands, and responds — all at a natural conversational pace. Proficiency level can be selected to match the student's skill.

How we built it

Deepgram — transcribes the student's speech in real time Claude Haiku — processes the input and generates a contextual French response Deepgram — voices the response back to the student Web browser through Vercel V0— microphone and camera access to simulate a live video call

Challenges we ran into

Keeping the speech-to-text, processing, and text-to-speech pipeline fast enough to feel like a real conversation. Latency between each step was the core technical challenge. Accomplishments that we're proud of Building an end-to-end voice conversation loop with an AI agent that responds naturally in French — without a paywall.

What I learned

Chaining multiple APIs in real time is harder than it looks. Latency compounds at every step, and tuning that pipeline was the biggest lesson.
