As an example, the host on "Would I Lie to You" is Welsh. Can't really notice his accent as being different even when it's next to a variety of other guests' accents. On the other hand, there was a blonde actress on once, and they did a little bit about both her and the host being Welsh... except her accent was thick, and I could surely recognize it as being different (as well as damn near unintelligible sometimes.)

His accent is very mild. Barely recognisable as Welsh

Hello Betty. I'll have five plain pies and an onion one as well!


Loooooooooove yhat shite! !

In truth there are many different Welsh accents. It's more of a 'family' of accents really.

The host on Would I Lie is the exceptional Rob Brydon.
Who appears in Gavin and Stacey with a much stronger accent.

Go to the motherlode.
Watch the strong accents. Then you can dilute as necessary.

I spent about a week trying to work out the accent of a boy in a Kia car advert.
He only had two lines.
Eventually realised he reminded me of Susannah and therefore concluded it was Brummie.
She was horrified. She came from Telford!

(Birmingham to Telford 33 miles)

Or don't.
It's a fun game but I admit I'll only ever get the broadest of American accents.

I'm not right good at identifying and naming an accent. But I can pick them out in a line up. And I can mimic most voices that I hear.
