Google launches Gemini 3.8 Flash TTS and Flash-Lite TTS with 100+ language custom voices
GoogleAI · x · 2026-09-23
Google has launched two new text-to-speech models:
- Gemini 3.8 Flash TTS: built for high-fidelity creative production (gaming, audiobooks, podcasts), with from-scratch voice design and line-by-line delivery control, including cues like <laughs> and backchannel interjections like |mhm|.
- Gemini 3.8 Flash-Lite TTS: tuned for cost-efficient scale, auto-adjusting tone and pacing for near real-time voice agents, dubbing, and bulk audio.
Both support custom voices in 100+ languages or 2,000+ production-ready voices, can direct back-and-forth conversations, and generate hours of consistent, glitch-free audio.
