Voice to Video
Role: Developer, Hackathon Participant Technologies: ElevenLabs Conversational AI, Heygen API, Bolt.new, Netlify Focus Areas: Voice AI, Video Generation, Rapid Prototyping, Public Web Interface
Project Overview
Built during the ElevenLabs Online Conversational Agent Hackathon — a 2-hour competitive sprint celebrating 1 million+ conversational AI agents on the platform, with $20,000+ in prizes. The project creates a complete ecosystem that transforms spoken input into polished avatar video content, accessible to anyone through a public web interface.
The core workflow: speak to an ElevenLabs conversational agent → agent generates a script and title → Heygen creates a professional avatar video → anyone can use it via a Bolt.new web app.
Why It Stands Out
- Dual prize qualification: entered both the main ElevenLabs prize and the Bolt.new partner track ($5,000 cash)
- Public-first: rather than a developer demo, the Bolt.new interface makes the tool usable by non-technical users
- Built and shipped in 2 hours: from idea to live Netlify URL within the hackathon window
Technical Stack
- ElevenLabs — conversational agent with custom webhook tool that triggers Heygen on voice input
- Heygen — avatar video generation API, producing 1280×720 video from script + avatar config
- Bolt.new — browser-based full-stack app builder used to create and deploy the public interface
- Netlify — one-click deployment from Bolt.new
