Question

What is one possible advantage of hearing the characters’ voices as opposed to silently reading the scene?

Answer 1

One possible advantage to hearing a character out loud in the voice of an actor or reader (or even one´s own voice) is that, if the histrionic and aesthetic execution and delivery of the reading is powerful and well-constructed, it could add depth to the character by revealing emotions and dimensions of the character that a silent and monotonous reading could risk passing over without emphasizing it and its importance.

Answer 2

If you hear their voices it can help you guess how they feel in the situation as well as guess the tone of the story.
