This blog post is a walkthrough of how I brought this experience to life.

The Problem Statement

The client needed a solution where users could:

• Join a virtual room in real-time

• Interact with a voice-based AI Agent that speaks and transcribes

• Customize the AI behavior dynamically (e.g., Sales Rep, Loan Agent, etc.)

• Run seamlessly on modern browsers with good UX and minimal latency

Think of it like a real-time version of a virtual meeting — but instead of another human, you're talking to a smart, contextual AI assistant. Similar to how a virtual sales consultant or a bank representative would assist customers online.

The Tech Stack

Here’s a quick rundown of the tools and frameworks that made it all possible:

• Frontend: React + Vite

• RTC & Audio: LiveKit SDK

• Backend: Python (with AI integration APIs)

• Transcription & Data Sync: WebRTC DataChannel + AudioTrack hooks

• Deployment: Self-hosted LiveKit server

How It Works (Project Overview)

When users join the room:

1. A connection is established to a LiveKit server using a JWT token.

2. The user's microphone is enabled (video optional), and audio begins streaming.

3. An AI agent — running on the backend — listens to the audio stream, processes it using NLP models (like GPT, Whisper, etc.), and responds with voice + transcribed text.

4. The frontend renders the audio visualization, transcription, and context like “Scenario”, “Agent Persona”, etc.

5. The conversation and behavior of the AI is controlled through a template system, making it reusable across domains like sales, banking, or education.

Unique Features

• Configurable Agent Templates
  Each room is bootstrapped with a different AI personality — a sales agent, a financial consultant, or even a tech support bot — using configurable templates.

• Audio-Only Mode with Visualization
  Users see the agent’s avatar and speech transcription in real time, giving a clean and distraction-free UX.

• Modular Connection System
  I created a reusable hook for managing LiveKit connections (useConnection) supporting cloud, manual, or environment-based modes.

• Sleek UI with Dark Mode
  Thanks to Framer Motion and Tailwind, transitions feel smooth and modern.

Challenges Faced

• Syncing voice responses with LiveKit’s audio tracks was tricky — especially when coordinating transcription with response timing.

• Managing real-time disconnects and reconnections gracefully.

• Ensuring consistent agent behavior across sessions with dynamic templates.

What’s Next?

The client is planning to scale this platform further:

• Adding support for video avatars and emotional tone detection.

• Storing conversation histories for future training and improvement.

• Extending this platform for recruitment interviews and training simulations.

Final Thoughts

This project truly showcased the power of combining real-time media with AI agents. Tools like LiveKit make it incredibly easy to build scalable RTC apps, and layering AI on top opens up countless use cases.
