AI text-to-speech and voice cloning for game characters
Altered Studio
Speech-to-speech voice morphing and character voice creation for game production

Overview
Altered Studio combines voice morphing, TTS, and voice cloning into a single audio production tool. Game developers use it to record their own voice acting, then morph it into distinct character voices — monster growls, elderly wizards, young heroes — without needing a large voice cast. The Real-Time Pro version also supports low-latency live voice changing during game streaming and VR experiences. Creator plan unlocks voice cloning from 5 seconds of audio.
Best For
- Solo devs who want to voice-act all characters themselves using morphing
- Sound designers creating unique creature and NPC voices
- Studios reducing voice cast size with AI voice transformation
