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

# What You Need to Know Google DeepMind released a new AI tool that can generate spoken audio with much finer control over how it sounds—think of it like being able to tell an AI exactly what emotion or tone you want in a voice, down to specific words or phrases. Instead of just getting generic speech, you can now add things like excitement, hesitation, or emphasis to make the audio sound more natural and engaging. This could be useful for creating better voiceovers, customer service interactions, or any application where how something is *said* matters as much as what is said.
