Indie game developers need character voices but can't afford union voice actors ($200–500/hour). AI voice design — creating distinct character voices with unique personalities — serves this underserved market. A portfolio of AI-crafted fantasy, sci-fi, and cartoon voices is a unique offering.
Design AI-generated character voices for indie game developers. Create distinct vocal personas: gruff warrior, wise wizard, cheerful shopkeeper, menacing villain, innocent child. Use ElevenLabs voice design to craft unique voices, then deliver dialogue lines with appropriate emotion and timing. Charge per character or per game project. Offer a 'Character Voice Bible' documenting each voice's traits.
  • Study voice acting fundamentals — pitch, pace, timbre, and emotional range — to design convincing character voices
  • Create a demo reel with 10–15 distinct character voices across different genres (fantasy, sci-fi, modern)
  • Offer integration support — help developers implement the audio files into Unity, Unreal, or Godot
AI Tools to Leverage: ElevenLabs, Descript, Audacity, Unity, Unreal Engine
