@shadowfals I checked out the wiki for Arch Linux. There are options, but it does not look very promising:

When the installation medium starts booting, press Down followed by Enter to boot with speech enabled.

You know, after the installer boot menu appears -- that you can't see -- but before the 15 second timeout that selects the default silent option.

(Of course, it is a distro for advanced Linux users, so it might not even fit for your use case.)
