tested this directly in AI Studio rather than just reading the launch post. zero setup since I already had a Google account logged in, went straight from the playground to generating a speech clip. gave it a line of dialogue with a hard tone shift in the middle (calm to panicked) plus a couple of vocal-burst tags like <gasp>, and it generated a 9-second clip in a few seconds with no fiddling. the tag system (style, expression, per-speaker settings) is more control than I expected from something this fast, and the dual-speaker screenplay mode is a real differentiator versus single-voice TTS APIs where you have to stitch turns together yourself.
