Yeah, this course really sucks without sound, especially since the language looks quite difficult to read. I will try again at a later date if they ever decide to add audio.
Notice that in Klingon his name is torgh, but the English is Torg. A lot of Klingon names are spelled differently in English, and this can be annoying. Sorry about that. But he's not tork, torch, tord or torq in either language.
Depends how you want to define "real". This language was created for the fictional race of Klingons from the Star Trek TV shows and movies. They hired a linguist to create it and it has a complete grammar and large vocabulary. Though it is invented (or constructed) most linguists view it as a functional and real language. However it has no native speakers and it's expansion is still quite artificial. There are some people who are fluent in the language and many of them have proved that it is possible to function speaking only Klingon for extended periods. Perhaps it is not a practical language, since it won't help you speak with a native culture and only in very rare cases can help you get a job. Many of the best speakers already speak multiple natural languages and for those that don't already speak multiple languages it can be a wonderful introduction to how learning a foreign language works. It is a fascinating language and can be a fun hobby. Please check it out!
