Kuay=Kuwait + way (join as short pronouciation)
Teow= T+E+owl (join as quick short pronounciation)
Char= Fried; Kuay Teow = the white flat noodles
By the way this is a local delicacy from Penang, Malaysia.
the word is in one of the chinese dialect (Hokkian - but local hokkian accent, may differ from original China Hokkian province pronounciation)
Hope the above can help. the pronounciation is about 90%.
