Troubleshooting AI response delays in VR

I’m using Unreal Engine 5.6 and MetaHuman. For the conversational AI setup, I’m using GCP Voice and the Gemini 2.5 Flash model.

I press the A button on the Meta Quest to ask a question, and I release my finger from the A button when the question is finished.

In the video, the first question received an immediate response, but from the second question onwards (after 40 seconds), I have to ask the question two or three times to get a response. Why is this happening?

Additionally, sometimes I’m in the middle of speaking, and the conversation suddenly ends without me finishing my thought. This also happens intermittently.

Hello @thanatos78,

Could you please share the logs?

It’s a packaged program, so I don’t have a log file. I can see logs in the Unreal Editor, but as I explained before, the editor version doesn’t register input from the Meta Quest controller. That’s why I can’t show you the logs.

Create a different level without VR configuration.

Could you please try again?
