Thanks Paul. It was more a matter of curiosity than anything. I suppose your speakers are chosen to be as regionally neutral as possible. Still, we all retain a bit of our local accent and I have detected some differences, not that there is anything wrong with that. I don't know where you learned your English, but in the US as in the UK there are huge regional differences in pronunciation and tempo. The midwest US is considered to be the most neutral, but there are areas in the midwest, e.g. northern Minnesota, Wisconsin, and the Michigan Upper Penisula where the accents of the original Norwegian, German, and Finnish immigrants are still detectable even among residents who don't speak a word of the language.
I've noticed now in the Platinum section, some of the differences between German, Austrian and Swiss words are noted. Very interesting.
