How to Auto‑Dubbing Multi‑Character Novels in Just 5 Minutes

Introduction

Today we share the newly updated AI automatic role segmentation feature for long‑form audio production. The tutorial shows how to create professional‑grade audio for novels, podcasts, or educational content.

Chapter 1: Feature Overview and Preparation

1.1 Long‑Form Audio Production Overview
