Gemini 3.1 Flash TTS is Google's newest text-to-speech model — 30 voice presets, 80+ languages, multi-speaker dialogue, style instructions. Skip the GCP setup and use it on Flixly with pay-as-you-go credits, next to ElevenLabs, OpenAI TTS HD, and every image and video model you need.
Natural-sounding voiceover in every major language. Built-in voice presets for narrator, announcer, character, casual dialogue, and more — no voice picker spelunking required.
Two voices, one generation. Pass a speakers array and the model renders a back-and-forth conversation — podcasts, skits, explainer video scripts, anime scene dialogue.
Vertex AI requires a Google Cloud project, billing, and service account keys. Flixly skips all of that. Credits start at $5, never expire, and cover audio, image, and video in one balance.
