Recently I told a tweenage student to "speak like the Queen" when spelling long words, and her mother said "I don't think you've ever heard the Queen speak, have you?" (headshake) "We must listen to the Queen's Christmas Message this year".
The Queen's Christmas Message used to be A Thing Australians listened to, before we had 27,000 TV channels and our own national anthem, and before Queen Elizabeth the Second, by the Grace of God Queen of this Realm and of Her other Realms and Territories, Head of the Commonwealth, Defender of the Faith became so elderly she stopped going on telly much at other times of the year.
Fortunately, not only is Her Majesty now on Twitter, but her Christmas messages are on Youtube, in case any kids you know want to listen to them, with a view to imitating her wonderfully rounded vowels and crisp and precise consonants while spelling. Here's last year's (click on this link if the embedded video below doesn't work):
I'm sure if we all enunciated words like "sculpture", "reconciliation", "sacrifice", "captured", "referendum" and "Ebola" like Her Majesty, we'd always spell them right.
If history is your thing, she's posher and less concerned with newfangled notions like humility in her first Christmas message (I do love the way she says "often", "very", "lost" and "old") of 1957, plus it's delightfully low-tech – no teleprompter then – and she has a super nice shiny frock:
If you're a republican and/or atheist, you might prefer to avoid the Queen's speech, in which case Penelope Keith of To the Manor Born might make a good substitute spelling voice model:
