Build AI Voice Agents with Gemini 3.1 Flash TTS (Audio Tags, 70+ Languages) in Google AI Studio

The video tests Google’s new Gemini 3.1 Flash Text-to-Speech (TTS) update and shows how to generate expressive audio and build AI voice-agent apps in Google AI Studio. It highlights improvements over the older 2.5 model, including more natural voices, speaker-level controls, audio tags, and support for 70+ languages, plus customization for style, pace, accent, and multiple voice presets. The walkthrough covers using the Generate Speech playground, adding an API key, switching voices via composer, and then using the Build section to create a text-to-speech app you can preview, export code for, download audio from, remix, and publish (publishing/deployment is paid, testing is free). It also reviews Artificial Analysis TTS leaderboard positioning, cost/quality tradeoffs, and notes audio watermarking via SynthID. The episode ends by promoting the AI Profit Boardroom community and trainings.
