Google announced that its Gemini API now offers two new text‑to‑speech (TTS) models. Gemini‑3.8‑flash‑tts is a high‑quality, studio‑grade voice model with regional dialects and long‑form stability. Gemini‑3.8‑flash‑lite‑tts is a faster, cheaper model meant to replace the older flash‑tts‑preview for real‑time voice agents.

Why it matters

Developers can now add more natural, cost‑effective voice output to apps, especially for agents that need real‑time conversation.
