I'm American and I say "malt-ee" (IPA
/məlti/). Probably one of the better ways to differentiate "American" english from British or Recieved Pronunciation
would be to use a word like Florida or origin, where you would get a /-or-/ in General American (unaccented to an American) and a /-ɒr-/ (are) in British English. The catch there is that speakers in New England will use the /-ɒr-/ sound like a British speaker, so you can't make a generalization there either. Sorrow and bother, among others, both retain the /-ɒr-/ sound in General American.
Here are the sources I used to figure this out:
Wikipedia: General American
Wikipedia: IPA Chart for English
: Shows Recieved Pronunciation, General American, and Australian English sounds and their IPA equivalents.
Wikipedia: International Phonetic Alphabet for English
There does not appear to be a Wikipedia chart mapping IPA directly onto German in either the English or German wikipedias, but I'm sure you could find one somewhere online if you actually knew German (which I don't).
Oh, and to try to answer the question at hand, it sounds to me like American english (General American), based on the borrow/sorrow difference. However, it isn't perfect and isn't really a great example of anything (it mispronounces the i in Florida-- that's the same in both dialects).
