Gemini 3.1 Flash TTS: the next generation of expressive AI speech

# Google's AI Can Now Speak More Naturally Than Ever Before Google has released a new AI voice technology called Gemini 3.1 Flash TTS that sounds more human and expressive—meaning it can better match emotions and emphasis when speaking aloud. You can already use this improved voice feature across Google's products like Gmail, Docs, and Android devices. This matters because AI-generated speech is now realistic enough that it could be genuinely useful for accessibility, creating voiceovers, or having AI assistants sound less robotic.
