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 targets high‑quality, studio‑like voices with regional accents and long‑form stability. The Flash‑Lite version is faster and cheaper, designed for real‑time audio agents. Developers can start using them via the new /v1beta/voices endpoint.
Why it matters
The models let apps add more natural, multilingual speech at lower cost, expanding voice‑based experiences.
