Google announced that the Gemini 3.8 Flash TTS and Gemini 3.8 Flash‑Lite TTS models are now generally available (GA) through the Gemini API. The Flash TTS model focuses on studio‑quality voice fidelity, nuanced accents and long‑form stability. The Flash‑Lite TTS version is faster and cheaper, aimed at high‑throughput, real‑time voice agents.
