Which accent does the Portuguese speaker have?
The Portuguese speaker does not have a carioca accent as I know it. I wonder which region her accent comes from.
Here is a map of the broad dialects of Brazilian Portuguese. I think the generic "sulista" fits it well, which would include wesleyjefferson's suggestion of paulistano. http://www.orbilat.com/Maps/Portuguese/Portuguese_dialects.html
This is way too simplified. This version is more accurate: http://pt.wikipedia.org/wiki/Dialetos_da_l%C3%ADngua_portuguesa#Brasil
But in my point of view, it's too strong to say that there are so many "dialects" in Brazil. It may seem that we can't understand each other very well, which is not the case. These "dialects" differ from each other basically from the accent (but they are all mutually intelligible) and vocabulary, which may differ a lot in usage, but each people know (or at least can guess) which are the words that are more standardized and may choose to use them when talking to someone from another region.
Not exactly the question you asked, but the woman that does the Portuguese Google Translate voice is from the city of Santos, in São Paulo . There's an interview with her at , and she does the Google Translate voice a few times starting at 01:58.
