Not open source. "You will need internet connectivity to validate your AccessKey with Picovoice license servers ... If you wish to increase your limits, you can purchase a subscription plan." https://github.com/Picovoice/orca#accesskey
Going online is a dealbreaker but if you really need it you could use ghidra to fix that. I had tried to find a conversion of their model to onnx (making their proprietary pipeline useless) but failed.
Hopefully open source will render them irrelevant in the future.
