(Put this on a different thread, but might as well copy it here.)
About accents, I was born in the US and grew up in New Zealand where there’s a distinctive accent (no, it’s not like Australian). Here’s a sample:
Mum’s a Yank and the schools I attended often had English and Lit teachers from England, so I didn’t pick up the sort of NZ speech in the viddy. Max Cryer, a pop linguist, claims that dental hygiene was so bad in colonial NZ that most Pakeha (anglos) had lost their teeth by the time they reached 30.
For rural couples, with a long haul to the dentist, a full extraction was a common wedding gift. Seminaries and convents decreed full extraction for novice priests and nuns, to spare the church long-term dental expenses.
Speaking with the imperfect dentures then available meant keeping your lips near closed. Try saying Fish and Chips that way. It comes out Fush and Chups , which is how most Kiwis pronounce it.
