My husband also helped me to pronounce crisps.

There's another one word they laughed when I pronounce biscuit.
I said I want
BIS-KU-WIT' instead of bis-kit .

Filipino fishermen here do pronounce the same. One time, me and hubby were staying at port with filipino fishermen and there were pupils around and they shouted "Hello BIS-KU-WIT"

.
One fisherman said, one of them is his skipper's son and sure they talked about his pronunciation.
