I can, but prefer to speak normally. The truth is, my accent isn't completely typical of the area I grew up in. First of all, I lived all over the Silicon Valley and what a lot of non-native SV people don't realize is the accent differs greatly between cities and even different parts of one city. So, my accent is a bit of a mix of the entire SV. There's also a bit of a Brit accent due to a lot of British programming I've watched over the years, as well as a slight Mexican accent.
No, I don't speak Spanish fluently, but do understand a bit of it.
