Gemini 3.1 Flash TTS Preview

by GoogleReleased 24 April 2026

Google's preview of 3.1 Flash TTS turns text into speech using Google's prebuilt voices. It is the earlier generation of Gemini speech: Google now points users to Gemini 3.8 Flash TTS for acted-out expression and long multi-turn dialogue, and to 3.8 Flash-Lite TTS for volume. Keep this one only for workflows that write style directions into the text, which the 3.8 models expect as separate settings.
