How to Convert EPUB to Audiobook
Converting an EPUB ebook to an audiobook used to require hiring voice actors, booking studio time, and spending thousands of dollars. With Narratemi's AI-powered converter, you can turn any EPUB file into a professional multi-voice audiobook in minutes.
Upload Your EPUB File
Drag and drop your .epub file or browse to select it. Narratemi's ingestion engine automatically extracts all chapters, preserves the table of contents, removes front matter (copyright pages, dedications), and prepares the text for AI analysis. Books of any length are supported, from short stories to 200,000+ word novels.
AI Analyzes Your Book
Our two-pass LLM system reads your entire book. Pass 1 detects all dialogue, identifies characters, and determines the narration style (first-person, third-person). Pass 2 enriches the script with emphasis markers and emotional context. Each character is automatically assigned a unique AI voice based on their role and personality.
Preview & Generate Audio
In Studio Mode, you can preview every line of the script, see which voice is assigned to each character, and listen to sample audio before generating the full audiobook. When ready, click Generate and receive chapter-by-chapter audio files plus a complete master file.
Download & Distribute
Download your audiobook in industry-standard formats. Your files are ready for distribution on major platforms including Spotify for Authors, Apple Books, Google Play Books, Kobo, and more. Full commercial rights included with every generation.

Why Convert Your EPUB to an Audiobook?
Reach more readers. The audiobook market is growing 25% year-over-year. Many readers prefer listening to reading, especially during commutes, workouts, and multitasking. By converting your EPUB to an audiobook, you tap into an audience you're currently missing.
Increase revenue. Authors who offer both ebook and audiobook formats see significantly higher total revenue. Audiobooks are premium products that command higher prices than ebooks.
Accessibility. Audiobooks make your content accessible to people with visual impairments, dyslexia, or other conditions that make reading difficult.
Stand out with multi-voice narration. Most AI audiobook converters produce flat, single-narrator output. Narratemi's multi-character voice assignment creates an immersive full-cast experience that sets your audiobook apart from the competition.
