Character not responding to voice input after following official tutorial (UE 5.3.2)

Hi! I’m using Unreal Engine 5.3.2 and followed this official Convai tutorial: https://www.youtube.com/watch?v=HHhkBd6NOlo&t=659s

I’ve set up everything as shown — including the ConvaiPlayerComponent, AudioInput Submix, and the VRPawn with ConvaiBasePlayer logic.

However, my character does not respond to voice input. I tested the mic — it’s working system-wide and in Unreal (confirmed via Audio Capture and AudioInput submix detection in logs).

Here’s what I’m seeing in the Output Log:

pgsql

CopyEdit

Accessed None trying to read property Chat_WB
Accessed None trying to read property MicSettingsWidget
Attempted to access TRASH_ConvaiPlayerComponent_23 via property ConvaiPlayer, but TRASH_ConvaiPlayerComponent_23 is not valid (pending kill or garbage)
ConvaiPlayerComponent: Found submix "AudioInput"

I’ve verified:

  • Mic permissions in Windows are enabled
  • AudioInput submix is correctly named and set
  • ConvaiPlayerComponent is attached to my pawn
  • All widgets exist in the project

Still, the character stays silent and does not respond. Any idea what might be causing this? Could it be a race condition or a component being destroyed?

Thanks in advance for any help!

Hello @theportal102,

Could you please check the microphone device in Settings? [F10] Can you see your speech in the chat box?

The microphone was very low.
