I think (just in general, not specific to her voice/accent!!) that would be a rather-desirable aspiration!
Daphne is
lovely: I've always adored everything about her (and the actor that plays her, Janet Leeves) mainly via that flawed-but-fantastic TV show 'Frasier'.
But I
never knew until now, looking at
her Wiki entry, that she
actually comes from Ilford in Essex (decidedly-south, forsooth!). I find this a highly-strange discovery (ok, I accept I'm late to the party, but...) since her pivotally-significant accent as Daphne in Frasier sounds as if she's genuinely-native to quite a few hundred of miles north of her actual point of origin.
In fact: I had (wrongly) decided, in a subconscious philological analysis, that she was probably a Yorkshire lass who'd moved early in her life to somewhere north of Manchester.
This discovery of falsity is disproportionately-unsettling for me: probably because it runs against my instinctive in-good-faith presumptions about people (even artificial ones). Also, in Frasier, nothing is ever directly-explained: instead, rather like a challenging new workplace, all characters must be (at first) learnt and understood by the viewer- and then they become trusted intimates of close understanding (this is to some extent true of all episodic sitcoms- but in Frasier, it's a fundamental precept).
This Daphne accent discovery (for me) is almost like the level of petty betrayal in finding-out that the neighbour you've always had a crush on is actually an android...
I think it's mainly because I find classic TV sitcoms incredibly-relaxing to watch, because of their predictable uncomplicated harmless niceness in a real-world of... (fairly-frequent) random complex harmful badness. And, always accepting that whilst they constantly tell us the little lies of theatre that do not matter, fundamentally they are the vessels of an admirable sort of truth.
A hardly-surprising self-evidencing conclusion; but: clearly a more-shaky edifice (internally, for me) than I might've expected.
TLDR- I thought she were proper north, and she's not: am pure gutted, 'natch
