You can listen to your cast of characters at any stage in the writing process, but it might be especially useful near the end when most of the story is fleshed out. It can be a good check of your story logic and add a last ingenious layer of polish.

Power moments in your story set up life-changing events and propel your story forward. Writing great dialogue often depends on the subtext you create in setting up these moments.
First-person narration lets you pack every moment with personality and explore your writer's voice to the max, but it can be a tricky point-of-view to pull off for the course of an entire book.
