Cross-gender voices are a tricky business. Even if you can really do a convincing cross-gender voice–and I know folks who can–the fact is that in a live reading, the audience knows that there’s only one person doing all the voices. There are two ways cross-gender voices can throw people out of listening. It’s really bad, and embarrassing, or it’s really good and shocking that a female voice is coming out of a man’s mouth. Either way, the listener drops the story for a moment.
