CastVoice is a cinematic story-to-audio-drama platform that transforms written stories into fully produced audio experiences. Each character is assigned a distinct voice, scenes include contextual sound effects, and the final output is a fully mixed audio drama. Characters can be cast using AI-designed voices, cloned voices, or by inviting others to contribute voice recordings. What problem does it solve? Producing high-quality audio storytelling traditionally requires voice actors, sound design, and manual editing across multiple tools. Existing AI tools focus primarily on text or single-voice output and do not support multi-character storytelling or end-to-end production. CastVoice addresses this by automating script structuring, voice generation, sound design, and audio mixing, while enabling collaborative storytelling through shared voice participation. How does it use ElevenLabs and this week’s sponsor? ElevenLabs powers the core audio pipeline, including text-to-speech generation with emotion-aware delivery, voice cloning, and contextual sound effect generation. Each character’s dialogue and scene audio are generated and combined into a single, cohesive audio output. Replit is used for building, running, and deploying the full-stack application, enabling rapid development and integration throughout the project.
