As The Goose says, Linear A has not yet been deciphered. But, curiously enough, several sites can be found around the Web with people claiming that they have unraveled the mystery. I think you won't be surprised if I add that they have reached lots of different conclusions.

For example, GJK Campbell-Dunn, from New Zealand, is convinced that Minoan Linear A is related to the Niger-Congo and Bantu languages of Africa; while Sergei Sergei V. Rjabchikov has read the text in the Phaistos disk relating it to Russian pronounciation.

These two are only two examples. Search, compare, and you can have a good laugh.
