Miu's voice uses OmniVoice, cloned from Miu's own recordings, so she always sounds like herself. It runs on your PC if you have an NVIDIA graphics card (the launcher installs it, about 12 GB). Without one, choose your own account on the launcher's Voice tab: Fish Audio or ElevenLabs speaks Miu's lines from her voice sample with your own API key. You pay the provider, she sounds a little different, and only the text of her lines is sent to it - never your microphone or your chat. The launcher unlocks the voice for each game it starts, so it works in licensed copies started from the launcher.
