If you then read the phonemes in the order of the clue answers from which the phonemes have been deleted, you get the clue "Antonym of generic". The antonym of "generic" is "specific"; deleting the first sound from that gives you the final answer, PACIFIC.
[Insert details of training clueing here.] In the 2002 Mystery Hunt, the property PACIFIC corresponded to the puzzle answer HAWAIIAN (see the hacking runaround answer). The trained answer is HAWAIIAN.
