I just shipped VoiceCast for the @ElevenLabs hackathon — a tool built for indie game developers who want unique character voices without hiring voice actors. Here's how it works: 1. Describe your character's voice (accent, tone, personality) 2. Enter 3–5 lines of dialogue 3. VoiceCast uses ElevenLabs' Voice Design API to generate a unique voice — then synthesizes each line 4. Download a ready-to-use voice pack (.zip).Whether you're making a dark fantasy RPG, a sci-fi shooter, or a cozy town sim — your characters deserve to speak.

Real-time multiplayer auction platform with an AI auctioneer that speaks. Users join rooms, create auctions, and bid against each other. An AI auctioneer powered by ElevenLabs TTS reacts to every bid with natural voice, builds tension through "going once... going twice...", and celebrates with a gavel slam and crowd cheer via the Sound Effects API. Users can bid by speaking — Realtime STT transcribes speech, Workers AI parses the dollar amount. Each room is a Cloudflare Durable Object managing bid state, timers, and WebSocket connections. Uses three ElevenLabs APIs (TTS, Realtime STT, Sound Effects) and three Cloudflare features (Durable Objects, Workers AI, Workers).
