Wehn I lived in Kent, "Speldhurst" could be "SpeldHARST".

Round here, Norfolk we have

"Potter heigham" - "potterum", "Weybourne" - "webburn" and "Stiffkey" - "stookey".

Of course areas can have there differences as to what is correct. I was born in Shrewsbury which like my mother born and bred there pronounce "Shrowsberry". I gather my grandmother (mothers mother) from Westbury might use neither of these, using "Salop" for the town.

The largest portion of my own life was N Wales so whlie not a Welsh speaker, I can say things like "Dwygyfylchi". Some English want to call a village I once lived in as "Pie dew" (it's spelt Pydew and more sort of "pud ow").
