I guess it depends on what exactly you want to do. If you want to get familiar with the components of a speech recognition system at the level of fiddling with a bunch of shell scripts until you have an end-to-end pipeline from recording speech samples to recognizing new speech, I can recommend the "Kaldi for Dummies" tutorial. [1] It helped me a lot to get an appreciation for the steps that go into making such a system work.
