This is the part almost nobody uses. Write the tag inline, anywhere in the script, and the model performs it. You are writing stage directions, not typing text.

[warm] This is a test of my cloned voice. [amused] If this sounds like me, [measured] the setup worked.

Every tag you can write

Square brackets for emotion, round brackets for breath and pauses. Free form works too: [whispers sweetly] does more than [whispering].

The small print, because it matters

That is the whole thing

If you build something with it, send it to me. I want to hear how far this goes.
