For sewing names, watching the quilt shows on PBS which are usually sponsored by local stores or major manufacturer's helps me with pronunciations.
One of the things I have a terrible time with is "Chick-fil-A", we didn't have them in Alaska (pre-1983), we didn't have them in the Seattle area until maybe 5 years ago? Only time I ever saw ads or mentions was at college bowl games and I have it in my head as "Chick-uh-fill-uh".
One of the the things I love about the internet is I can hear pronunciations, so much easier than the old dictionary marks...
