I think they meant to say "American English" not "American Accent".

American English has some differences that explains why their accent is what they are. E.g. the "u" in "colour" is missing ("color"). The "u" was a schwa sound.

the schwa sound comes from the fact a lot of English words came from French origins (as the schwa is most notable in the English language). In in 1066 William the conqueror took the English crown, banned the English language and installed the French language as the dominate language. English eventually came back eventually, but kept hold of some 1,000+ French words when it did come back. Hence why the schwa sound ended up being taken into English words and pronunciations.

Skipping a lot of boring details and a chuck of history (wikipedia exists for a reason)... when it came to America, eventually that sound (along with several vowel sounds) changed or were dropped... Basically sounds became harder, the schwa was dropped because vowels because clearer, harder or more defined...

If you are doing a synthesizer for specifically the British English or American english then phonetically speaking, there will be some things different. Vocaloid, however, for some reason uses a bit of both english set ups... :-/
