Unabridged is the complete text, word for word — the default for most audiobooks. Abridged is an edited-down, shorter version. Check the label before buying if completeness matters.
Amazon's marketplace for getting an audiobook made and onto Audible, Amazon, and Apple Books — the common on-ramp for indie authors. You hire a narrator, approve the audio, and distribute. (Audible's royalty terms are shifting in 2026, so check current ACX terms.)
Amazon's audiobook service: a subscription that gives you credits or all-you-can-listen access, plus the option to buy titles outright. The biggest store, deep in the Amazon ecosystem.
Nonfiction about how work, companies, money, and careers actually function — strategy, leadership, economics, the case studies behind them. A commute-and-gym staple; many listeners run it at higher speed to mine the ideas, which is its own argument for sampling the narration first.
Choosing the narrator or full cast for a book — matching a voice to the material. One of the highest-leverage calls in a production: the right voice can carry a title, the wrong one can sink it.
A profile of a book's major characters built before recording, so a narrator keeps each voice consistent across a long book — who appears where, how they look, talk, and move. On a big cast, a narrator may juggle twenty-plus voices. (See also the two senses of prep.)
Sells audiobooks individually with deep daily-deal discounts and no subscription — a good spot for bargain-hunting specific titles.
A token included with some subscriptions that you swap for one audiobook, regardless of its price — so it pays off most on long, expensive titles. Several services use the model (Audible, Libro.fm); they differ on rollover and expiry. Library apps like Libby do not use credits; they lend.
Supervises a narration session — catching missed words and keeping tone and character voices consistent. Brought in mostly for complex or high-end fiction, often alongside a producer.
Fiction built on the impossible — magic, invented worlds, mythic creatures — from sprawling epics to quieter cozy strands. One of audio's strongest categories: long runtimes suit the format, and a great narrator turns a big cast into a world you live in.
Fiction set in a real past, weaving invented characters through actual periods and events. Rewards a narrator who can carry period voices and accents — a strong performance is half of why a vanished world feels present in audio.
Nonfiction about the real past — events, eras, figures, and how they connect — from doorstop narratives to focused deep-dives. Long, well-narrated histories are an audio staple; a skilled reader turns names and dates into a story you follow rather than a list you endure.
The waitlist for a library audiobook when every copy is loaned out. You are notified when your turn comes up. The trick regulars use: stack several holds so something is always arriving.
A library lending app with no waitlists — titles are always available instantly, but your library caps how many you can borrow each month.
Fiction whose first job is to unsettle — dread, fear, the wrong thing in the dark — across supernatural, psychological, and visceral strands. Audio may be horror's ideal home: a voice in your ears in a quiet room gets under the skin like nothing else.
The International Phonetic Alphabet — the formal, standardized way to write exactly how a word is pronounced. One of the formats pronunciation research is delivered in. (Not the beer.)
The free app most US public libraries use to lend audiobooks and ebooks. Borrow with a library card, returns are automatic, no late fees. Made by OverDrive.
An audiobook store that shares each sale with an independent bookshop you choose — the indie-bookshop alternative to Audible, with DRM-free files.
Fiction where the language, characters, and ideas matter as much as the plot — the "how it's written" is part of the point. A contested, fuzzy label, so we use it loosely. In audio, a narrator attuned to rhythm can make prose sing; a flat read can flatten it.
Fiction set inside game-like worlds with explicit rules — levels, stats, quests — where the numbers are part of the story. A divider for some listeners: the stat blocks fans love can read oddly aloud, so narration quality matters more here than almost anywhere.
The finished, delivered audio — the polished, quality-checked files that become the audiobook listeners hear. The end of the production line, the thing loaded to the stores.
A true first-person account of a slice of the author's own life — shaped like a story rather than a full life history (that's autobiography). Audio's sweet spot, especially author-narrated: hearing a life in the voice that lived it carries a weight no other format matches.
Fiction organized around a puzzle — usually a crime — that the reader works to solve alongside the protagonist, from cozy whodunits to hard-boiled procedurals. A natural listen: the slow reveal pairs well with the steady company of a narrator.
The person who performs an audiobook — the voice you hear. The good ones are giving a performance, not just reading aloud, which is why a sample is worth the minute.
The service that powers most US library audiobook and ebook lending. The practical thing to know: OverDrive is the engine, Libby is the app you use.
How narration is priced and measured — per hour of finished audio, not hours worked. One finished hour can take several hours to produce, so PFH is the unit that matters in rates and budgets.
A widely used audiobook proofing/QC tool. Upload the manuscript and the recorded audio, and it compares the two — flagging misreads, dropped or added words, and overlong pauses — so the proofing pass goes faster. Built to support human proofers, not replace them: the tool catches mechanical mismatches, the human still judges tone and intent. (Not the only such tool, but the best-known.)
Two things in narration: pronunciation prep (researching how to say hard words) and character prep (profiling a book's cast so voices stay consistent). Worth knowing which sense is meant.
The checking stage on the way to the master — comparing recorded audio against the manuscript to catch misreads and dropped words. Best results pair automated tools with human judgment: the tool flags, the human decides.
The standard recording method. After a flub, the narrator stops, the software rolls back a few seconds to match their tone, then drops back into record at the exact spot — a clean take with little editing.
The version of the book a narrator performs from — usually a watermarked PDF marked "recordable," distinct from the earlier "prep version" used to scope the book before recording.
Working out how to pronounce everything a narrator might stumble on — names, places, foreign phrases, technical terms — and rendering it so they can simply read it aloud. The deliverable is usually a word list.
A plain-English way of writing pronunciation, as an alternative to formal IPA — the word respelled how it sounds, lowercase except the stressed syllable. Easier to read at speed.
The person or company that holds a book's audio rights — the one with authority to have an audiobook made and collect its earnings. You must be one to publish on a platform like ACX.
Fiction centered on a love story, with the emotional payoff as the point — by long convention, an optimistic ending. A juggernaut in audio: dual narration (one voice per lead) has become almost a genre signature.
Romance and fantasy fused so the love story and the magic carry equal weight — neither just a backdrop. The breakout category of recent years. We use "romantasy" when the romance is load-bearing to the plot, not a subplot. A natural fit for audio.
Room tone is the ambient "sound of silence" in a recording space; the noise floor is its baseline background level. Keeping both low and consistent is why narrators record in booths and treated spaces.
The short preview clip every major store lets you play before buying. The single best habit for avoiding a narrator mismatch — a few minutes tells you if a voice works for your ear.
Fiction that extrapolates from science and technology — space, futures, AI, what-ifs — across hard, soft, and everything between. Ages well in audio; full-cast productions can make a starship or an alien world land in a way the page can't.
Nonfiction aimed at changing how you live, work, or think — habits, productivity, psychology, growth. Huge in audio for an obvious reason: people listen while doing the very things (commuting, exercising) the books are about improving. Worth a sample, since delivery varies wildly.
Making and releasing your own audiobook without a traditional publisher: confirm you hold the rights, narrate it yourself or hire a narrator, record to spec, then distribute via ACX or a wider service.
Stops playback after a set time — or, on many apps, at the end of the current chapter — so you can fall asleep to a book without losing your place. "End of chapter" is the listener favorite.
Adjusting playback speed, usually 0.5× to 3×. Most listeners settle around 1.1×–1.5×. Push up for dense nonfiction; ease down for a performance worth savoring. No "right" speed — it is per book and per listener.
Select Premium plans include a monthly amount of audiobook listening time from Spotify's catalog, with top-ups available. Good as a perk if you already pay for Spotify; tighter if audiobooks are your main thing.
Where an audiobook is recorded, on a spectrum — from a narrator alone in a home booth up to a publisher's staffed studio or a contracted service provider. The setup scales to the title.
Two ways to pay: a recurring fee for credits or access (subscription), or buying each title outright (à la carte). Subscriptions reward frequent listening; à la carte suits a few books a year.
Fiction built on tension and momentum — the clock ticking, the threat closing in. Thriller leans on pace and stakes; suspense on dread; they overlap so much we pair them. Audio amplifies both: a narrator's control of pace is its own kind of suspense.
Nonfiction that reconstructs real crimes and investigations — the case, the people, the aftermath. Has exploded in audio alongside the podcast boom it's kin to; the documentary-style narration that suits it is a format strength.
Amazon's feature for keeping a Kindle ebook and its matching Audible audiobook in sync, so you can switch between reading and listening without losing your place. Needs both editions of the same title.
The spreadsheet a researcher hands a narrator, keyed by page number — columns for page, content, phonetic, source, and notes — covering every tricky pronunciation. The artifact this glossary is named after.
