Create your own voices with Gemini 3.8 text-to-speech

Design entirely new vocal personas from scratch for gaming, immersive audiobooks, or dual-speaker podcasts using natural language prompts - directing every performance line by line with nuanced acting cues, pacing, back channeling, and dialect shifts. Or, recreate consistent adult vocal profiles from just a 30-second audio sample of your voice or a voice you have the rights to use, backed by built-in consent verification, SynthID watermarking, and C2PA credentials to protect both developers and their vocal talent.
