BookyAI Audio

A render failed halfway. Press Render again — it resumes from where it stopped, and already-finished chapters are never redone. › ACX rejected my BookyAI Audio files with "RMS is too low. Raise the level of this file X dB", although the app showed the RMS inside the range. What should I do? Update BookyAI to version 1.9.13 or later, then on the Audio page click "Start fresh" and "Render" again (or use "Re-re… › After updating to v1.6.3, my first audio render is re-doing all chapters. Why? Expected, one time only. The fix for missing sentence endings changes how narration passages are prepared, so previousl… › Are the introduction, prologue, appendices etc. narrated? Yes, optionally. In the Render panel you can toggle each front-matter and back-matter section on or off. › Can I change the narrator or speed after rendering? Yes. Pick a different voice or speed and re-render. Re-renders are unlimited. › Can I change the narrator's name spoken in the credits? Yes. Set any narrator name you like (a pen name, your brand) and that's what's spoken in the opening and closing credit… › Can I listen before the whole book is done? Yes. Chapters appear in the list as soon as each one is rendered — press play on any finished chapter while the rest ke… › Can I re-render a single chapter? Yes. Every chapter — and the opening credits, closing credits and retail sample — has its own re-render button. › Can I remove the engine to free up space? Yes — in Settings you'll find the BookyAI narration engine card with a delete option. It re-downloads automatically the… › Can I use my Audio license on two computers? No — one machine per key, same as your BookyAI license. If you got a new computer, contact support and we'll move it fo… › Can I use my own voice or clone a voice? No. BookyAI Audio uses its built-in narrator cast. › Do I need anything else to use it? Just the BookyAI app (with your BookyAI license activated) and a BookyAI Audio license. No API keys, no accounts, no ot… › Do I own the audiobooks I create? Yes, 100%. You keep all rights and all royalties. › Do pronunciations apply everywhere? Yes — in every chapter, in the credits and in the retail sample, every single time the term appears. › Does BookyAI Audio need a permanent internet connection? No. It checks your license periodically, and you get a 30-day offline grace period. Rendering itself happens entirely o… › Does BookyAI Audio use paid AI services or APIs? No. Audio generation is powered by BookyAI and runs 100% on your computer. There are no per-book fees, no per-minute ch… › Does BookyAI Audio work on Windows and Mac? Yes. It's built into the BookyAI desktop app on both Windows and macOS. › Does rendering send my book anywhere? No. Your manuscript never leaves your computer during narration. › Does the app pick voices based on my book's language? Yes. The voice carousel shows the narrators that match the language of the selected book. › Every chapter failed with "outside the retail spec" and even the re-renders were identical. (fixed in v1.6.2) If the numbers shown were very low (e.g. "RMS −60-something dB"), the chapters were actually silent: the narration engi… › How do I create an audiobook? Three steps: 1) In the Audio tab, pick a finished book from your library. 2) Choose a narrator (press play to hear each… › How do I get the whole audiobook as ONE file? After the initial render finishes, use the "complete audiobook" export. You choose exactly which sections to include, a… › How do I hear a voice before choosing? Press the play button on any narrator card — each voice introduces itself so you can judge the tone. › How is the audiobook cover made? It's generated automatically at 3000×3000 (the size stores require) from your book's cover, using your configured AI im… › How long does a render take? It depends on your computer and the length of the book — typically from under an hour to a few hours for a full-length … › How many voices are there? 54 lifelike narrators — male and female, American and British English plus international voices. › How much does each audiobook cost to produce? Nothing. Render 1 or 1000 — the price of your license never changes. › I bought BookyAI Audio later (not with my order). How do I activate it? You received a license key by email (format: BND-XXXX-XXXX-XXXX). Open the Audio tab in the app, enter the key and clic… › I bought BookyAI Audio together with my BookyAI order. How do I activate it? You don't have to do anything. Open the BookyAI app on the computer where your BookyAI license is activated, go to the … › I clicked "Start fresh" on the Audio page but the track list still shows the wrong sections. Did it work? Yes. "Start fresh" removes the cached narration and all rendered files right away; before version 1.9.12 the track list… › I got a refund. What happens to the add-on? The Audio license is deactivated automatically. Books and audiobooks already on your computer stay on your computer. › I got the error "That key isn't a BookyAI Audio license key." You probably entered your main BookyAI key. The Audio add-on has its own separate key — check your purchase email for t… › I got the error "This license is already activated on another computer." Your key is bound to a different machine. Contact support and we'll transfer it to your new computer. › I just bought it and it's still locked. What do I do? Purchases can take a minute or two to arrive. On the Audio tab, click "Check again". Make sure you're on the same compu… › I press play on a voice or chapter and hear nothing.

The engine restarts itself and retries automatically. If the message persists, restart the app and press Render again —… › I stopped a render / closed the app. Did I lose my progress? No. Progress is saved continuously. Press "Render" again and it resumes exactly where it stopped. › Is there a publish guide for every book? Yes. Every rendered audiobook ships with its own publish guide: which file goes where, what to type in each field, how … › My audiobook shows the Prologue twice (for example "03. Prologue" and "04. Prologue") and the Epilogue twice after I re-rendered some chapters. How do I fix it? Update to BookyAI version 1.9.12 or later, then on the Audio page click "Start fresh", confirm, and click "Render" once… › My book has unusual names/terms. Will they be pronounced correctly? Use the Pronunciation panel: click "Scan book" and it finds names, places and special terms. For each one you can type … › My chapters showed "Peak −2.x dB — outside the retail spec" and re-rendering never helped. (fixed in v1.6.3) That was a defect in our loudness mastering: the limiter controlled peaks in a way that let certain chapters (typically… › Something else isn't working. Restart the app first (this fixes most one-off issues, and render progress is always saved). If the problem remains, co… › The Render button is disabled. Why? Usually the book isn't finished yet, or its language isn't supported by the narration engine. Check that the book has g… › The app says it can't verify my license but I'm online. Click "Retry connection" on the unlock screen. If it persists, your network may be blocking the license server — try an… › The engine download is stuck.

The publisher name from your Settings. › What does "experimental" mean for Japanese and Mandarin? Those voices work, but pronunciation accuracy may vary more than in the other languages.

(from v1.6.3) On the Render panel, "Start fresh" clears all cached narration and every rendered file for that audiobook — your voice,… › What files do I get?

English (American & British), Spanish, French, Italian, Portuguese and Hindi — plus Japanese and Mandarin as experiment… › Why do the RMS numbers next to my audiobook chapters look lower after updating to 1.9.13, although I did not re-render? Because the app now reports the whole-file RMS, the measure ACX uses, instead of the speech-only measure shown before. … › Why is something downloading the first time I use it? The first render (or first voice preview) downloads the BookyAI narration engine (about 88 MB), one time only. After th… › Why isn't the references/bibliography section narrated? Reference lists aren't meant to be read aloud (and stores discourage it), so they're always excluded. › Will my audiobook pass the stores' technical review? The files are mastered specifically to the retail spec, so they're built to pass. (Each store also reviews content and … ›
