Finding the right narrator is one of the most consequential decisions in audiobook production. A great narrator makes listeners forget they're listening to audio — they're simply inside your world. A poor fit, even from a technically skilled voice actor, can make an excellent book feel off from the first chapter.

The good news is that the market for audiobook narration is large, professional, and increasingly accessible to independent authors. Here's how to navigate it.

Where to Find Audiobook Narrators

ACX (Audiobook Creation Exchange)

ACX, owned by Audible and Amazon, is the largest marketplace for audiobook production. As an author, you post your project with a brief and a sample script, and narrators audition directly on the platform. You can also browse narrator profiles and invite specific voices to audition.

ACX offers two payment models: royalty share and pay-per-finished-hour (PFH). For a first audiobook with modest sales expectations, royalty share reduces upfront cost. For an established title with proven sales, PFH keeps your long-term earnings intact. We'll cover this in detail below.

Voices.com and Voice123

These are general voice talent marketplaces, not audiobook-specific. You'll find narrators here, but the vetting is lighter — narrators list their own rates, and you post a job and receive proposals. Quality varies widely. The advantage is access to narrators who don't work exclusively on ACX, including some with broadcast experience. Expect to screen more auditions to find the right fit.

Backstage

Backstage is a professional casting platform used primarily by actors. Many experienced voice actors and SAG-AFTRA narrators have profiles here. Rates tend to be higher, but the talent pool includes narrators with strong audiobook credits. Better suited if you're looking for a narrator with a specific type of professional experience — accents, character voices, or a particular genre reputation.

Personal Referrals

Ask other authors in your genre who narrated their audiobook and whether they'd recommend them. Writing communities, genre-specific Facebook groups, and author forums on Reddit are productive places to ask. A referral from an author in your exact genre — especially if you've listened to and enjoyed that audiobook — is often the most reliable shortcut to finding the right voice.

Royalty Share vs Pay-Per-Finished-Hour

On ACX, you choose between two payment structures:

  • Royalty Share: The narrator records your book for free in exchange for 50% of your ACX royalties. Your effective royalty drops from 40% (exclusive) to 20%. On a book selling modestly, this is a reasonable deal. On a bestseller, you're paying a narrator thousands of dollars per month indefinitely. Royalty share agreements on ACX lock you into ACX exclusivity for seven years.
  • Pay-Per-Finished-Hour (PFH): You pay the narrator a flat rate per finished hour of audio. Experienced narrators typically charge $200–$400 per finished hour; top-tier narrators with major publisher credits may charge $500+ PFH. An 80,000-word book produces roughly 8–9 finished hours, so total narration cost runs $1,600–$3,600 for a mid-range narrator. You own the finished files outright and can choose any distribution arrangement.
Key calculation: 9,200 words of prose typically equals one finished hour of narration at a professional pace. Divide your word count by 9,200 to estimate your audiobook's finished hours — this is what PFH rates are based on.

How Auditions Work on ACX

When you post a project on ACX, narrators submit auditions — typically 3–5 minutes of your sample script, recorded and edited. You review them through the platform and can request revised auditions or additional takes.

To get useful auditions, your sample script matters enormously. Choose a passage that:

  • Includes dialogue from at least two characters with distinct voices or personalities
  • Has some narrative prose so you can hear how they handle description and interiority
  • Contains a range of emotional tones if your book has them
  • Features any unusual words or names you'll want to confirm they can handle

A 2-page sample is usually sufficient. Longer samples don't necessarily produce better auditions — narrators are busy and a clear, focused sample gets more high-quality responses.

What to Listen for in Auditions

Evaluating auditions is partly objective and partly instinctive. Here's what to listen for:

  • Tone match: Does this voice feel right for your genre? A cozy mystery and a military thriller require different tonal registers. A voice that's technically excellent but tonally wrong for your book will feel off for all 8 hours.
  • Clarity and diction: Every word should be intelligible at normal listening speed. Mumbling, rushed consonants, or swallowed endings are red flags — these are hard habits to correct mid-production.
  • Pacing: Good narrators vary their pace with the material. Exposition moves differently than action or dialogue. Listen for whether they're reading on autopilot or actually performing the material.
  • Character differentiation: In fiction especially, narrators need to distinguish characters without becoming a cartoon. Each character should feel distinct without requiring theatrical voices. Listen to how they handle your dialogue sample.
  • Audio quality: The recording should be clean, with a consistent room sound and no audible hiss, clicks, or reverb. Low audio quality in an audition is a warning sign about their home studio setup.

Writing Your Narrator Brief

Once you've selected a narrator, a clear brief saves time and revision rounds. Your brief should include:

  • Tone and mood: Describe the overall feel — "measured and atmospheric," "warm and conversational," "taut and propulsive." Reference audiobooks or narrators they might already know as reference points.
  • Setting and world: Relevant context that might affect accent or cadence. A Victorian-set novel versus a near-future dystopia calls for different registers.
  • Character guide: For each named character, list their approximate age, their accent or regional origin if relevant, their emotional baseline (reserved, volatile, warm), and any defining speech patterns. This is especially important for fiction with a large cast.
  • Pronunciation guide: List every unusual word — character names, place names, invented terms, foreign words — with phonetic spelling. Don't assume they'll guess correctly. "Siobhan (shih-VAWN)" is a brief note that prevents a costly retake.
  • Narrative voice: If your narrator is first-person with a distinct voice, note that — a wry, unreliable narrator reads differently from a solemn one.
Practical tip: Create your pronunciation guide as a table: left column the word as written, right column the phonetic pronunciation. Send it before recording begins, not after the first batch of files arrives.

Working With a Narrator During Production

Most ACX productions work in batches: the narrator records and delivers 15-minute sections (called "retail audio samples" in ACX terminology), you review them, and flag any errors or retake requests before they proceed. Respond promptly — professional narrators often have multiple projects running simultaneously, and delays on your end add weeks to your timeline.

Keep retake requests focused. Distinguish between actual errors (mispronounced name, skipped line, audible mistake) and personal preference ("I'd like a slightly warmer tone here"). The former is always a fair retake request. The latter is reasonable in moderation but shouldn't become a page-by-page redirection exercise — narrators aren't infinitely available for aesthetic adjustments once you've approved the casting and the brief.

File Delivery and Technical Specifications

For ACX submission, narrators typically deliver:

  • MP3 files, 192kbps or higher
  • One file per chapter or retail audio sample
  • Consistent room tone across all files
  • A "retail audio sample" (a 5-minute excerpt, usually the opening) for the product listing

ACX enforces technical QC specs on the finished audio (noise floor, RMS levels, peak values) — most professional narrators are familiar with these requirements and master their files accordingly. If you're hiring a narrator who's newer to the platform, flag the ACX technical requirements early so they're accounting for mastering in their workflow.

Before handing your manuscript to a narrator, it's worth ensuring your text is clean — errors in the manuscript become expensive to fix in post-production. EditRoast can review your manuscript for editorial issues before you hand it off, saving you retake costs down the line.
