Star Trek: Klingon.

Star Trek: Klingon (CD­Rom)

This game consists of three CD's, two of them containing the actual game, which is more of an interactive video, than a true computer game. The game features all the know actors from TNG, and gives some insight in the Klingon culture, but apart from that there isn't much more to be gained there.
     However the third CD is a "Language Lab" featuring a Klingon­style interface, with which you may learn some Klingon word; you may choose what kind of words you wish to learn from several different categories. The Language Lab is also said to be featuring a tool to help you with your pronunciation, the computer samples your speech and gives you advice and suggestions for improvement (I haven't tested this part of the software myself, so I can't tell you whether it does a good job or not).
