Yea, I'm Trinidadian, and even though my accent has changed significantly from living in Canada for 7 years, people and especially voice recognition get confused by some of my speech patterns.

Example is that people always hear 50 when I say 30, because of how I pounce the "y". Anything ending in "th" or "ing" gets confused a lot by people who don't know me.

It's kinda funny to keep track of :)
