Implement a keybinding that activates microphone recording only when pressed (push-to-talk).
Add a UI indicator so the user clearly sees when recording is active.
This creates the foundation of the voice interaction workflow.
I implemented a basic push-to-talk microphone system inside Unreal Engine 5.
First, I created a new Input Action for “PushToTalk” and assigned a keyboard key (for example: V). I then added this Input Action to the Project Settings under the Input section so the engine can detect when the key is pressed or released.
Next, I opened the Blueprint of the player character and added logic to enable or disable the microphone based on the push-to-talk key. When the key is held down, the microphone activates, and when it is released, the microphone turns off. I also added a simple on-screen indicator that shows when the microphone is active.
