I just have a regular North American accent. I used to have certain dialectal features to my speech (for example, I grew up merging the phonemes /O/ and /a:/ so I said "cot" and "caught" the same way), but I've spent a lot of time studying languages and dialects and stuff and taught myself to lose a lot of that. Listening to me, you could easily find out I'm from America or Canada, but you wouldn't be able to tell where, except that I'm not from a place where they have heavy dialects like Boston or the Deep South.
