Of course, the speed of an audio novel could be slower, depending on the development of the story and the emotional expression of the characters. In some slow-paced storylines, you can slow down the speech to make the character's breathing and voice more natural and better express emotions. In some fast-paced scenes, you can speak a little faster to better attract the attention of the audience. In short, the speed of an audio novel should be in line with the requirements of the story and the character's performance.
