And of course, you'd want to ensure that the helper-agent'ss audio-cues remain pleasant to human ears – and not just computer-to-computer screeches. To achieve this, you'd add yet another adversarial agent, that's trying to discriminate original audio from the helper-enhanced audio – without access to the video. Only audio-help that successfully fools this 3rd agent, and is thus relatively-indistinguishable from the unassisted-audio, gets added to the game.
