Current AI voice tools generate flat readings without dramatic interpretation. Content creators want to direct pace, emotion, and emphasis like a voice director.
Build a web app that accepts text and provides sliders/tools to adjust vocal delivery parameters. Include presets for different genres (drama, comedy, documentary).
Monetize through premium voice models and commercial usage licenses. Independent filmmakers and audio drama producers would pay for professional-grade results.
Start with basic emotional tone controls (happy/sad/angry) and pacing adjustments. The risk is large players like ElevenLabs adding similar features to their platforms.
