I have no idea what that means, but the answer is that we don't know what the "Trojans" spoke. The mythic Trojans in epic speak Homeric Greek, just like their Greek enemies. The "real" Trojans who inhabited the place called Troy in the Late Bronze Age might possibly have spoken a language called Luwian, but there is not much evidence either way.

Luwian was an Anatolian IndoEuropean languge. A Hittite seal of 1275 BCE was found at Troy in 1995 and was written in Luwian (I think it had another script also but I can't find it out at the moment). Some of the names in Homer seem to have a Luwian connection: Priam might be from pariya-muwa 'very courageous' in Luwian. Aeneas and Anchises also seem to be Anatolian in origin. This connection was argued by Calvert Watkins, and he was one of the foremost historical linguists of the 20th century. This means it is probably the best theory based on the evidence at hand.

edit some words

Some Minoan Linear A tablets have been found in the area around Troy, but I don't think anyone thinks that the Minoans had enough hegemony there in any period to transmit their language to the locals.
