+      If `Enum.AudioApiRollout|Enabled`, the voice chat setup is represented and controlled by
+      an `Class.AudioDeviceInput` object. More specifically:
+
+      - An `Class.AudioDeviceInput` will be created and parented to each voice-eligible `Class.Player`.
+      - An `Class.AudioEmitter` will be created and parented to each voice-eligible player's `Class.Player.Character`.
+      - An `Class.AudioListener` will be created and parented to `Class.Workspace.CurrentCamera`.
+
+      If `Enum.AudioApiRollout|Disabled`, the voice chat setup is done through an internal-only system.
+
+      Currently, setting this to `Enum.AudioApiRollout|Automatic` has the same meaning as `Enum.AudioApiRollout|Disabled`.
+      However, in the future, `Enum.AudioApiRollout|Automatic` will become `Enum.AudioApiRollout|Enabled`, so that new
+      experiences can achieve greater customization over voice.
+
+      Voice chat can be enabled or disabled in its entirety via `Class.VoiceChatService.EnableDefaultVoice|EnableDefaultVoice`.
