I have actually been pretty impressed by how the remaining AR16 racers can almost pronounce Seychelles correctly. Of course it is a French word, so the first "e" is pronounced as the letter "a"particularly Dan/Jordan. Here are two official pronunciations:
Sey·chelles audio (sa -shel, -shelz) with the "e" having a bowl-shaped notation over it (upside down circumflex) and means extra-short and the a having a hoizontal bar over it, which means equivalent to the "a" sound in day, pain, whey or rein.
