Setup and installation is very complicated

It's open-sourced, but very well maintained by the core group of Johns Hopkins University's speech recognition laboratory. It has been offering a great suite of tools and libraries for speech scientists to utilize to perform their research experiments with ease as well as for industry practitioners to exploit to build business solutions for customers who are interested in paying for dependable speech recognition solutions.
