Google announced that Gemini 3.8 Flash TTS and Gemini 3.8 Flash‑Lite TTS are now generally available (GA) as part of the Gemini API. The Flash model is designed for studio‑quality voice, regional accents and long‑form content, while the Lite version is cheaper and faster for high‑throughput, real‑time audio. Both models are accessed via the new /v1beta/voices endpoint.

Why it matters

Developers can now add more natural, customizable speech to apps without the latency or cost of earlier models.
