Duet Narration is the happy medium between solo and full-cast narration. Unlike dual narration, in which a male narrator reads the chapters written from the male perspective and does all the voices in those chapters (both male and female), and vice versa, in duet narration the woman voices all the female characters and the man voices all the males.
It gives narrators the opportunity to work off each other and perform what some people see as a more realistic dialogue exchange. In terms of Romance, Duet Narration can make intimate scenes feel more authentic. Plus, it’s a LOT more fun when you screw up and you’re not the only one laughing.
