Hah... the test wasn't that specific
I'll try to remind myself about this and I might record it someday when I have a mic hooked up
Also; no we don't all talk the same there's a significant difference between folks from Maastricht, Kerkrade or Roermond... pretty much every city has a distinct dialect and thus a pretty specific accent. Well, except for Heerlen, a city which has a bastardized version of all local dialects... heck, their accent to me sounds one of the more thrashy Limburg accents.
I'm still wondering what shibolleths there are for all these cities in my area. (for those clueless about that odd looking word, it's hebrew; Shibboleth - Wikipedia, the free encyclopedia
Yep. You guys have had a thousand years or more to develop all those local accents. Way longer than any of us....
But I do wonder if transportation, technology and migration are changing it across the pond as much as it's changing here....
