I'm short and have a pretty high voice (been told I sound lile a child on more than one occasion). Every job I've had to work so much harder than everyone else to get ahead. Fortunately for me the field I'm in performance is based off of metrics that I excel at so I pretty much out perform everyone else by default and that has gotten me noticed and keeps me high on the list when promotions or raises come up. I still get talked over in meetings all the time if I don't have a more authoritative person to back me up when I have something to say though.
