I'm looking for an offline speech recognition software for Linux which can handle also German language and which is easy to use and configure.

I already tried CMU Sphinx and a few more others, but all of them had one in common: they have been way too complicated to install/use, mainly because of lack of a good manual and also because of a very crude concept (I try to avoid the word "usability" in this context).

So...is there a speech recognition software out there which can be set-up and configured in finite time, is able to execute scripts on recognised commands and works fully offline, means does not need a cloud service or remote server to analyse spoken words? I'm also willing to pay money for a working and usable solution!

Every hint and idea is welcome!

Thanks!

PS: I'm aware of the thread Is there any decent speech recognition software for Linux? - but the answers given there do NOT point to offline solutions!
