Introduction: when and why to use this checklist

Use this checklist when you have a finished ebook and want to publish a professionally narrated audiobook without hiring voice actors, booking studio time, or blowing your production budget. It works for first-time conversions and for authors scaling an entire backlist.

At AudiobookGen, our analysis of self-publishing workflows shows that most conversion projects stall not because the technology is hard, but because authors skip preparation steps or choose the wrong platform for their goals. This checklist closes that gap.

Before you begin, consider four things:

• Your business case. Audiobooks open a separate revenue stream. Platform-native tools like Google Play Books auto-narration and Amazon KDP Virtual Voice have lowered the barrier significantly, with KDP Virtual Voice audiobooks going live within 72 hours of publishing (Amazon KDP Virtual Voice tutorial summary, 2024).
• Your conversion method. AI narration tools range from free platform options to premium generators like AudiobookGen, which produces HD-quality MP3s from EPUB files using natural-sounding AI voices. Match the tool to your timeline and budget.
• Platform requirements. Each distributor has eligibility rules. Amazon KDP Virtual Voice, for example, supports ebooks up to 240,000 words (Amazon KDP Virtual Voice tutorial summary, 2024). Know these limits before you start.
• Realistic expectations. AI narration quality has improved dramatically. ElevenLabs now offers studio-quality generation across 70+ languages (ElevenLabs, 2025), and tools like Narakeet provide 900 voices across 100 languages (Narakeet, 2025). Expressive, multilingual output is now achievable without a recording booth.

Work through each phase in order. Check off every item before moving to the next step.

Phase 1: prepare your ebook file

Before you upload anything, your source file needs to be clean, correctly formatted, and structurally sound. Skipping this phase is the single most common reason conversions produce garbled audio, missing chapters, or mispronounced text. Invest 20 to 30 minutes here and every subsequent step becomes faster.

• Validate EPUB file structure using an EPUB validator tool
• Remove or fix broken internal links and cross-references
• Check for consistent heading hierarchy (H1, H2, H3 structure)
• Ensure all special characters, accents, and diacritics render correctly
• Remove or replace images with alt text descriptions for audio context
• Verify chapter breaks are properly marked with semantic tags
• Test font consistency and remove embedded fonts that may cause parsing errors
• Strip out page numbers, headers, and footers that don't apply to audio
• Confirm table of contents is auto-generated, not manually typed
• Review footnotes and endnotes—decide whether to include or convert to inline text

Step 1: validate your file format

Confirm your ebook is saved in a format your chosen tool accepts. AudiobookGen works with EPUB files, which is the standard format most ebook creation tools export by default. If your file is currently a PDF or Word document, convert it to EPUB first using a tool like Calibre (free, open-source ebook management software) before uploading.

What you should see: A clean EPUB file under your target platform's size limit, with no corruption warnings when opened in a reader app.

Step 2: clean up formatting and special characters

Open your EPUB in a text editor or Calibre's editor and remove or replace the following:

• Decorative symbols such as section breaks using asterisks, tildes, or Unicode ornaments
• Footnote markers and endnote references that will be read aloud as gibberish
• Tables and text boxes, which most TTS (text-to-speech) engines read out of sequence
• Curly quotes and em dashes, replacing them with straight quotes and commas or colons

Step 3: audit your metadata

Check that your EPUB metadata includes an accurate title, author name, and chapter titles. AudiobookGen uses automatic chapter extraction, so well-labeled chapter headings ensure the tool splits your content correctly without manual intervention.

Step 4: build a pronunciation guide

Read through your manuscript and flag any words likely to be mispronounced: character names, place names, technical terms, and foreign phrases. Create a simple text document listing each word alongside its phonetic spelling. You will use this in Phase 3 when you review narration output.

Step 5: verify file integrity

Upload your EPUB to a validator such as the EPUB Validator at the W3C (World Wide Web Consortium) or open it in Adobe Digital Editions. Fix any reported errors before proceeding.

What you should see: Zero critical errors in the validation report and all chapters appearing in the correct order.

Note on word count: If you plan to use Amazon KDP Virtual Voice, confirm your manuscript does not exceed 240,000 words, the stated eligibility limit for that platform (Amazon KDP Virtual Voice tutorial summary, 2024). A clean, validated file also makes it straightforward to check your word count accurately at this stage.

Phase 2: select your conversion platform and voice

Your platform choice determines your royalty structure, distribution reach, voice quality, and how quickly your audiobook goes live. Evaluate each option against your genre, target audience, and production budget before committing, because switching platforms mid-project adds unnecessary rework.

• Compare royalty structures across platforms (Amazon KDP, Google Play Books, Apple Books)
• Check maximum word count limits for your ebook (Amazon KDP Virtual Voice: up to 240,000 words)
• Review available voice options and quality samples on each platform
• Verify language and accent availability matches your target audience
• Confirm distribution reach—which platforms does each service cover?
• Check turnaround time from upload to live publication
• Review pricing models: one-time fee vs. per-word vs. royalty-based
• Test voice samples with a 2-3 minute excerpt from your ebook
• Verify metadata requirements and submission guidelines for each platform
• Confirm customer support availability if issues arise during conversion

Step 4: compare platform eligibility rules and royalty structures

Review the following major options side by side:

What you should see: A shortlist of one or two platforms that match your distribution goals and word count confirmed in Phase 1.

Step 5: select a voice that matches your book's tone and genre

Voice selection directly affects listener retention. A thriller needs a different cadence than a self-help title.

• Identify your genre's conventions. Nonfiction and business books typically suit a clear, measured tone. Fiction benefits from a voice with expressive range.
• Match voice to your audience's language and accent expectations. If your readers are primarily British English speakers, a neutral American accent may feel misaligned.
• Use AudiobookGen's six AI voices (Charon, Kore, Fenrir, Aoede, Puck, and Orus) to audition options directly against a sample chapter. Each voice has distinct tonal characteristics suited to different genres. See the full walkthrough in how to create an audiobook from your EPUB file in 3 steps.

What you should see: A confirmed voice selection with a sample passage that sounds natural at your chosen playback speed.

Step 6: confirm platform support for your file format and word count

Before uploading, verify:

• Your ebook file format is accepted. AudiobookGen accepts EPUB files directly, eliminating any conversion step.
• Your word count falls within platform limits. Amazon KDP Virtual Voice caps eligibility at 240,000 words, as noted at the end of Phase 1.
• Your target language is supported by the voice library on your chosen platform.

What you should see: A green light on all three compatibility checks before you move to narration configuration in Phase 3.

Phase 3: configure narration settings and review

With your file uploaded and voice selected, configure how the narration will actually sound. This phase covers speech rate, pronunciation accuracy, and structural markers. Getting these settings right before final processing saves you from re-running the entire conversion later.

• Set speech rate (typically 150–180 words per minute for audiobooks)
• Configure pronunciation rules for character names, technical terms, and proper nouns
• Mark chapter breaks and section boundaries for proper pause placement
• Test narration on a sample chapter before full conversion
• Listen for unnatural emphasis or mispronunciations in dialogue
• Adjust punctuation if the AI misinterprets sentence structure
• Set volume normalization to ensure consistent audio levels
• Configure pause duration between chapters and sections
• Review and approve the full audio file before publishing
• Export in the required format (typically MP3 or M4B) for your platform

Step 1: Set your speech rate

Adjust the narration speed to match standard audiobook pacing. Most commercially produced audiobooks land between 150 and 170 words per minute. A rate that feels natural during a quick preview can become fatiguing over several hours of listening.

In AudiobookGen, use the playback speed customization control to dial in your preferred rate before processing begins. Start at the default, then test one notch slower if your content is dense or technical.

What you should see: A speed setting confirmed before you trigger final processing.

Step 2: Define pronunciation rules for names and terms

AI voices apply standard phonetic rules, which often misfires on character names, brand names, technical jargon, and proper nouns. Build a pronunciation list before previewing.

• Write out phonetic spellings for any word flagged as unusual
• Pay particular attention to foreign-language terms and invented names in fiction
• Check platform documentation for how to submit custom pronunciation entries

Voice choice and pronunciation editing are widely recognized as the key differentiators in AI audiobook workflows. A well-configured pronunciation dictionary is what separates a polished result from an obviously automated one.

Step 3: Preview sample chapters and correct errors

Generate a preview of at least your first chapter and one middle chapter. Listen for:

• Mispronounced names or terms you missed in Step 2
• Unnatural pauses mid-sentence caused by punctuation formatting
• Chapter headings being read aloud instead of treated as structural breaks

Update your pronunciation rules and recheck your EPUB formatting from Phase 1 if either issue appears.

What you should see: Clean, natural-sounding narration with chapter breaks landing at the correct structural points, not mid-paragraph.

Step 4: Confirm chapter markers and section structure

Verify that every chapter break in your EPUB has translated into a distinct audio section. Listeners navigating by chapter depend on this. Platforms that support automatic chapter extraction, including AudiobookGen, handle this during processing, but a manual review confirms accuracy.

Checklist for Phase 3:

• Speech rate set and confirmed
• Pronunciation rules entered for all flagged terms
• Sample chapters previewed and errors corrected
• Chapter breaks and section markers verified

Phase 4: publish and distribute your audiobook

With your audiobook reviewed and approved, the final phase covers uploading your files, completing your metadata, and getting your title live on the platforms where listeners can find it. Each step here directly affects discoverability, royalty accuracy, and how quickly your audiobook reaches your audience.

Get started with AI Audiobook Generator for ebook to audiobook conversion AI Audiobook Generator.

• Complete all metadata fields: title, author, narrator, description, keywords
• Upload cover art in the required dimensions and format
• Write an engaging audiobook description optimized for discoverability
• Set pricing and royalty preferences according to platform guidelines
• Assign ISBN or ASIN if required by your platform
• Schedule publication date or publish immediately
• Verify the audiobook appears correctly on all distribution channels
• Set up pre-order if your platform supports it
• Create a launch plan: social media, email list, book blogs
• Monitor sales, reviews, and listener feedback post-launch

Step 1: Upload your final audio file

Export your completed audiobook as a high-quality MP3. AudiobookGen outputs files in standard and HD quality formats, both ready for direct platform upload. Confirm the file is complete and plays without gaps before submitting.

Step 2: Complete your audiobook metadata

Add the following before submitting for review:

• Title and subtitle exactly as they appear on your ebook
• Description written for audio listeners, not repurposed from your ebook listing
• Cover art meeting platform dimension and resolution requirements
• Keywords and categories that match how listeners actually search

Step 3: Set pricing and royalty preferences

Review platform terms carefully. Amazon KDP Virtual Voice titles in the beta workflow have carried list prices between $3.99 and $4.99, according to Amazon KDP Virtual Voice tutorial guidance (2024). Confirm your pricing aligns with platform eligibility rules before submitting.

Step 4: Submit for review and monitor approval

Submit your title and note the expected approval window. Amazon KDP Virtual Voice audiobooks go live within 72 hours after publishing, according to Amazon KDP Virtual Voice tutorial guidance (2024). Check your publishing dashboard daily until you receive confirmation.

Step 5: Verify live availability

Search for your title on the platform as a listener would. Confirm the cover, description, sample audio, and pricing all display correctly.

Checklist for Phase 4:

• Final MP3 uploaded and verified
• All metadata fields completed
• Pricing and royalty settings confirmed
• Title submitted for platform review
• Live listing checked and confirmed accurate

Common mistakes to avoid

Even a well-planned ebook to audiobook conversion can fail at the final hurdle. These five mistakes consistently derail projects, delay publication, or quietly reduce sales long after launch. Catching them early saves significant rework.

• Skipping file cleanup. Unformatted text, stray special characters, and broken paragraph tags cause narration errors that are difficult to catch until you hear the finished audio. Clean your source file thoroughly before uploading.

• Ignoring platform eligibility limits. Amazon KDP Virtual Voice, for example, accepts ebooks up to 240,000 words (Amazon KDP Virtual Voice guidance, 2024). Submitting an oversized or unsupported file format stalls publication unnecessarily.

• Choosing a voice without previewing it. A voice that sounds neutral on paper can feel mismatched against your genre or tone. Always listen to a full sample passage before committing.

• Neglecting pronunciation review. Mispronounced character names, technical terms, or proper nouns damage listener trust immediately. Build a dedicated pronunciation pass into your workflow before final export, using custom pronunciation controls where your platform supports them.

• Publishing with incomplete metadata. Missing descriptions, incorrect categories, and absent keywords reduce discoverability directly. Complete every metadata field before submission, not after.
