Google Releases Gemini 3.8 Flash TTS and Flash-Lite TTS With Prompt-Based Voice Design

Google launched Gemini 3.8 Flash TTS and Flash-Lite TTS with prompt-based voice design, 2,000+ voices, and consent-gated voice replication via API.

Google released Gemini 3.8 Flash TTS (creative direction, character voices) and Flash-Lite TTS (high-volume, cost-efficient production) through the Gemini API and Google AI Studio, API-only with no open weights. Flash TTS generates new voices from text prompts across 100+ languages and dialects, offers a 2,000+ voice library (up from 30), and ranks first on Hume AI's Voice Design Benchmark with 71.4. Voice replication requires a 30-second sample plus a matching verbal consent recording, and all output carries SynthID watermarking with C2PA credentials for replicated voices.
