Let's pretend to be Professor Higgins: He seems to be reading from a script: he would not normally speak English like this - the grammar is much better than his pronunciation, also his rhythm and intonation do not follow the meaning. This makes the job harder as we don't get to hear any personal quirks of grammar or vocabulary. The accent is unusual - he could be from an unusual background, or be speaking unusually for the recording either deliberately or because of the text. A good example of the problem is his pronunciation of 'edit', which is very strange. English is a second language for him, and he has learned American pronuncation at a school or from TV; he is not from an anglophone background. The lack of any French or Arabic sounds probably rule out non-anglophone Africa, so he is not African. The aspirated dentals rule out the Latin world, we are left with Asia. From here on I am just guessing, based purely on probability, and the forward vowel positions, China?

Symf, is this you speaking?

hm that sounds similar to a friend of mine, and he's from Serbia.
