Gemini 3.8 TTS - Google's New AI Voice Is Scary Good!!

Google just dropped Gemini 3.8 Flash TTS and Flash Lite TTS -- two new text-to-speech models that let you direct AI voices like actual actors. In this video, I demo a multi-voice showcase with distinct personalities, walk through the benchmark results on Hume AI's public leaderboard, and then show you step-by-step how to build your own voices in Google AI Studio. You'll learn how to: - Design a custom voice from a personality description (age, accent, tone, style) - Use voice replication to clone your own voice (where available by region) - Create multi-speaker dialogues with different styles and expressions - Add filler words for more natural-sounding speech - Direct voices with emotional controls like whispers, projection, and more - Access 2,000+ ready-made voices across 100+ languages - Generate API code to use the model directly in your application Both Flash and Flash Lite took the top two spots on Hume AI's overall quality ranking, with Flash ranking first for creating new voices. If you make training videos, product videos, or anything that needs voiceover in multiple languages, this is worth trying. All opinions are my own and do not belong to my employer.
