I cannot change the Pace in the TTS Director's Note Speaker Setting

Hi everyone,

I’m experiencing a UI/UX bug with the new Gemini 3.1 Flash TTS Preview in Google AI Studio where the voice pacing control is broken upon opening the panel.

The Problem:
When opening the Speaker Settings sidebar, the “Pacing” selection under the Director’s Note section automatically initializes on “The Drift”. Clicking on a different setting does nothing. I’ve selected “Natrual” before, but now the setting doesn’t change to anything else.

What I’ve Tried:

  • Attempting to click and change the selection immediately upon loading a fresh voice workspace.
  • Overriding the pacing instructions manually using inline text narrative tags and the “Sample Context” box, but the model still follows “The Drift” preset rule.
  • Clearing browser cache and trying a hard reload (Ctrl + F5), but it still initializes with the dropdown completely frozen on this option.

It looks like the dropdown state payload for the Director’s note is broken or failing to register click/selection events on initial render. Is anyone else locked out of changing the pacing from “The Drift” on load? Hopefully, the engineering team can roll out a quick interface fix!

Wow. I posted right after you, having not seen this post. Can confirm it’s happening to me too, with both Pace and Accent (Gemini 3.1 Flash TTS Preview - Unable to change Pace or Accent)

Bro, I am also facing the same issue. Unable to change Pace and Accent. Only Style is accessible.

Hello Everyone,

Thanks for reporting this. The issue with changing Pace and Accent in the TTS speaker settings should now be resolved. Please refresh Google AI Studio and try again, and let us know if you still run into it.
