Well that depends... Leo-minster, Lem-stuh, Leemunster, Lomunster, Lominster, Lominser... New England vs England vs the street in Derby (Darby, not Derby), vs the posh street outside of Bristol.
Paris in France, is "Paree." Paris in Florida is "paris." Perris in California is "Pa-rees" or "Pe-riss" and sometimes "Paris" depending on the age of the person speaking, but that street named Lyon over in Hemet, just East or Perris, (He-met according to Google but Hemmet or 'emmet according to the locals) in California is Lee-on, Lee-yon, or, as one local said, "Lion, and why are you trying to be all fancy?" but is written as "Lyon" and was not named for the city in France but for the construction company that built the area.
Worcestershire is Wurstuh, Wurst-uh-shur, Wurst-uh-shuh, Wurst-er-shuh, Wor-ster-shire depending on where in the UK you are. My local UK dialect, a combination of the bad side of Grangetown outside of Carddiff (Dad) & BBC given English (Mum) so my pronunciation is, and always has been, "wurster-shuh."
Today I learned that El Salvador calls Worstershire Sauce as "Salsa Inglesa" and I shall now use that just to confuse people.
I love local pronunciations because it makes me aware that our languages are continuously evolving.
Leo-minster. That's pretty much Google.
Local is something more along the lines of leh-minster. (Or maybe Leh-minstuh though you don't really get the Southie dropped r's in this area of the state.)
Which are also commonly used throughout New England in particular. Google Maps still butchers a lot of the pronunciation although it's better than it used to be. (I live about 15 minutes north of a Worcester and even closer to a Leominster which also isn't pronounced like you or apparently Google would expect.)
