Voice Shell is a terminal you control entirely by voice. Say "create folder", "show files", or "delete everything" — shell executes in real time with streaming output via WebSocket. Dangerous commands trigger a voice confirmation: the terminal literally asks "Say yes or no." Built with ElevenLabs Scribe v2 + Flash v2.5, featuring a multilingual regex parser with 25+ patterns across 6 languages.

Echo Impostor is a procedural social stealth game where ElevenLabs voice AI becomes the central gameplay mechanic. Every run generates a new crew voiced with unique TTS personalities — one is an impostor, and the player must interrogate suspects, listen for vocal contradictions, and collect audio evidence to survive. We extended ElevenLabs far beyond dialogue: contextual voice tutorials teach the player, collectible audio logs reveal ship lore, dynamic room narration builds atmosphere, and proximity alerts warn of danger — all paired with AI-generated music and SFX for a fully immersive, voice-driven investigation.

Echo Impostor is a procedural social stealth game where AI-generated voices are the core gameplay mechanic. Each run creates a new spaceship with crew suspects — one is an impostor. Players interrogate characters using ElevenLabs Text-to-Speech, listen for contradictions, and accuse the right suspect. Sound effects and music are also generated via ElevenLabs APIs, making every run sound unique. Built with Zed.

MoodCast generates personalized cinematic audio experiences — pick a mood and get an AI-narrated story, original music, and timed sound effects, all created in seconds. It uses 4 ElevenLabs APIs in parallel: TTS v3 with Audio Tags for emotional narration, Music API for scene-matched instrumentals, Sound Effects for cinematic cues synced to story moments, and Conversational AI as the story-writing engine. Built entirely with Kiro using Specs for structured feature development, Steering docs for hackathon focus, and Agent Hooks for automated testing. What makes it special: one tap turns a mood into a full audio movie — voice, music, and sound design composed together, not stitched from a library.
