AI narration for your own books
Narrator narrates your imported books with natural AI voices running on your iPhone. AI voices cover English, French, Spanish, Italian, Portuguese; another 25+ languages use built-in iOS voices. The free plan narrates 25,000 characters a day and works offline once the book is imported.
What the AI voices sound like
The honest description is “a competent reader” rather than “a performance”. Sentences land where they should, commas get a beat, questions rise at the end, and paragraphs do not run into each other. What you do not get is characterisation — no distinct voices for dialogue, no acting. A professionally narrated Audible edition is a different thing and will stay a different thing.
The bar that matters is whether you can listen for two hours without fatigue, and that is where these voices separate from a screen reader. The most common thing reviewers say about Narrator is a version of “less robotic than most other readers”, which is roughly the right expectation to arrive with.
Because the narration runs on the phone rather than a server, there is no rendering queue: press play and it starts talking, with no upload and no waiting for a job to finish.
Which languages have AI voices
This is worth stating precisely, because language counts in this category are usually inflated by counting two different things as one.
| Natural AI voices | English, French, Spanish, Italian, Portuguese — five languages. These are the lifelike ones, and the reason to use the app rather than the accessibility settings you already have. |
|---|---|
| iOS system voices | Another 25+ languages, using the voices Apple ships with iOS. Perfectly usable for getting through a document; flatter and more mechanical over a long book. |
Both are real options and both are included. The distinction only matters if you were expecting AI-quality narration in a language that does not have it yet — better to know that before you import a 400-page book.

Adjusting speed and pacing
Playback runs from 0.5x – 3x. In practice most people settle somewhere between 1.1x and 1.5x for fiction, drop back to 1x for anything dense, and use the high end only to skim.
One thing that comes up constantly and deserves a direct answer: playback speed does not change your character budget. The free plan counts characters of text narrated, not time spent listening, so a chapter costs the same at 3x as it does at 0.5x. Listening faster gets you through the book sooner in wall-clock terms; it does not get you more of it per day.
Offline and on-device
Once a book is imported and the voice you picked has been downloaded, narration needs no connection at all. Nothing about your library is uploaded — the file is parsed on the phone and the speech is generated there.
- Works on a plane, on the underground, or with the phone in airplane mode.
- Playback continues with the screen locked, and the lock-screen controls work as they should.
- Your books and your position in them stay on the device.
- A voice needs a connection the first time it is downloaded, and only then.
What the free plan covers
The AI voices are part of the free plan, not held back for subscribers. What is limited is how much of them you get per day.
Free plan at a glance
No account, no trial expiry. The cap is on narration — that means listening, not just export.
| Every day | 25,000 characters — about 4,000 words, roughly one chapter, or 28 minutes of listening at 1x. Resets daily. |
|---|---|
| Lifetime pool | 150,000 characters — about 25,000 words, or 2.8 extra hours. Only drawn on after you pass the daily limit. |
| Plus | $4.99/month or $29.99/year. Removes the limits. |

Around a chapter a day, permanently, without an account. Plus at $4.99 a month removes the caps if you want to listen for longer than that in one sitting.
Limits
What it doesn’t do
- The AI voices read; they do not perform. No character voices, no acting, no emotional range.
- Natural AI narration covers 5 languages. The other 25+ use the iOS system voices.
- Unusual names, invented words and honorifics are often mispronounced, and there is no pronunciation editor.
- 25,000 characters of narration a day on the free plan, plus a 150,000 character lifetime pool.
- Synthetic narration of a book you did not write is for personal listening — it cannot be sold or published.
- iOS 26.0 or later, iPhone and iPad only.
Common questions
Natural AI narration covers English, French, Spanish, Italian, Portuguese. Another 25+ languages are available using the voices built into iOS, which are usable but noticeably more synthetic over a long session.
No. The cap counts characters of text, not minutes of audio, so playing a chapter at 2x costs exactly the same as playing it at 1x. Speed is purely a listening preference.
Not perfectly. Invented names, transliterated names and honorifics such as -chan or -san are often mispronounced, and there is no per-word pronunciation editor to correct them. Most listeners stop noticing after a chapter or two, but if a name appears constantly it will keep sounding wrong.
Yes, once the book is imported and the voice has been downloaded. The speech is generated on the phone, so a flight or a tunnel makes no difference.
