"My voice is my passport, verify me."

*password I believe. Upvoted.

No, "passport". It was clearly a reference to the voice authentication hack in _Sneakers_.

Indeed. They took a bunch of smaller words and spliced them together to fake his voice print. Cambridge Consultants are clearly harvesting our voice prints for the CIA. ;)

We have something very similar in the UK tax service (HMRC) which is "password".

Probably just make refinements to the model they're using to classify samples.

The sentence is obviously taken (with some modifications) from the sample used by the speech accent archive ( http://accent.gmu.edu/howto.php ), which was constructed specifically to include every relevant phonological context in American English. (Not that this was necessarily achieved, but it was the goal.)

Leave them on random people's voicemail, probably.

I'm American and I get mixed results between 89% American and 53% British on my normal accent. My pronunciation of "call" and "to" seems to tip the scales towards British and most of my other words are not strongly highlighted.

I can reliably fake a British accent although I seem to get stuck on frog and store still sounding American. When I do the stereotypical Texas style "yee haw" accent I get 99% American.

It's actually a famous sample; I remember seeing it in linguistics classes. It just happens to contain a lot of words that reveal differences between English dialects.

I am too and only got 65% British.
