Summary
Gemini 3.8 Flash TTS targets expressive, controllable voice creation, while Flash-Lite TTS is optimised for high-volume generation and voice agents. Google says both models include consent verification, SynthID watermarking and C2PA credentials for replicated voices.
Why it matters
Voice generation is moving from fixed presets toward programmable, multilingual performance and identity creation, increasing both creative utility and impersonation risk.
