While it's good that you have an ethics page: https://lyrebird.ai/ethics/, it only has two ethical guidelines:

* Spread awareness of this technology

* Your digital voice remains yours

I would feel a lot better about this if you also had explicit ethical boundaries, for example disallowing users impersonating someone else, e.g. Donald Trump, Barack Obama. "Your digital voice remains yours" sort of sounds like you won't use/share my digital voice with others, but doesn't directly address whether bad actors can maliciously impersonate someone who hasn't registered with Lyrebird.
