Voice changes how you relate to AI. When you type, you edit, self-censor, and compose. When you speak, you think out loud. Voice is more immediate, more honest, and more natural. A real AI voice companion takes advantage of that. Lucy OS1 is voice-first by design. You speak, she listens and responds with a real voice. The result feels like a conversation, not a software interaction.
