Could voice be a turn off?

If you chat with someone online and you start to like them and feel interested enough to want to meet them...(you've seen their picture and have seen them on cam but never heard them talk) and suddenly one day after a few years of chat, this person talks, and maybe they don't sound exactly how you expected them to sound... Would that turn you down? as in You no longer want to meet them, or at least not interested in them as a boyfriend/girlfriend?
