Gemini 3.8 Flash TTS brings custom voices and directed dialogue
Google has introduced Gemini 3.8 Flash TTS and Flash-Lite TTS for expressive speech generation. Flash focuses on custom voices and detailed performance direction; Flash-Lite targets high-volume use. Google describes consent checks for voice replication and SynthID watermarking. Developers should distinguish features rolling out now from Enterprise availability and voice remixing marked as coming soon.
