AI text-to-speech and translation for your PDF & EPUB
AI Reader
PDF & EPUB to Voice
Any text. Any language.
Neural voices read your documents aloud, in your language.
Real-time contextual translation.
Available for Windows and Linux, with Android on Google Play.
What it does
Three things, working together in one reader.
Auris Reader combines neural text-to-speech, real-time contextual translation and adaptive PDF detection in a single desktop app that keeps your library on your device. Start with a 14‑day free trial — cancel anytime.
Neural voices in 12 languages, no compromise
Listen to EPUB and PDF books with natural-sounding neural voices. English and Spanish are ready out of the box, with accents from the US, the UK, Spain and Mexico; ten more languages arrive as free voice packs. Each sentence lights up as it is spoken, and your place is kept across sessions.
- EPUB 2/3 and PDF
- The voice you pick sets the language it reads in
- Predictive pre-buffering, no gaps between sentences
Contextual translation as you listen
Translate your reading in real time without losing context. Each sentence is translated together with the ones before it, and proper names keep the translation they got the first time, so a character does not change name from one page to the next.
- Offline translation in every plan: on the desktop in 15 language pairs; on Android, each language once downloaded
- Proper names stay consistent while you read
- Translates while the TTS keeps playing
Adaptive PDF cleaning
Read complex PDFs without garbled output. Auris Reader detects running headers and footers automatically, so the voice reads what you would actually read — not the page numbers, not the metadata, not the artifacts.
- Running headers and page numbers stay silent
- Pull quotes stop interrupting the paragraph
- A profile built from the opening pages
The highlight you hear
The line glows the instant the voice reaches it.
Every sentence is synced with the audio. An adaptive predictive pipeline keeps the highlight, the buffer and the translation in lockstep — so your eyes can follow, or rest. Your call.

How it works
From file to voice in under a minute.
No cloud upload, no DRM headaches. Sign in once, open a book on your computer and press play. That is it.
Open your file
Open any EPUB or PDF in Auris Reader. The file never leaves your device: the online voices only receive the sentence being read.
Pick a voice
Pick one of more than 20 neural voices in 12 languages, or stick with the default. The voice you choose sets the language it reads in.
Listen and translate
Press play. The highlight follows the voice in real time. If the book is in another of the 12 languages, it can be translated as it is read and you hear it in yours: on its own where there is an offline pair, or with online translation if you choose it.
Made for serious readers
“Your library, your pace, your language — without sending a single page to anyone’s servers.”
Why Auris Reader
How it compares with the readers you may already know.
Auris Reader reads aloud, translates as it reads and keeps your files on your device. Some of these readers do part of that for free, and the table shows which.
| Auris Reader | Calibre | Edge | Speechify | NaturalReader | Voice Dream | |
|---|---|---|---|---|---|---|
| Platforms | Windows, Linux, Android | Windows, Mac, Linux | Windows, Mac, Linux, Android, iOS | Windows, Mac, iOS, Android, web | Windows, Mac, iOS, Android, web | iPhone, iPad, Mac |
| Opens EPUB | Yes | Yes | No, PDF only | Yes | Yes | Yes |
| Neural voices | Yes, 12 languages | Yes, local | Yes | Yes | Yes | Yes |
| Translates the book while reading it | Yes | Not stated | Selected text, in a side panel | Not stated | In AI Chat, in the online app; plan not stated | Not stated |
| Reads without uploading your file | Yes | Yes | Yes | No, cloud library | Online apps: no, cloud library. Desktop: not stated | Yes |
| Free tier | 14-day trial | Free, no limits | Free | Limited | Limited | No |
| Price | €4.99/month | Free | Free | Free plan, or subscription | Free plan, subscription, or a one-off desktop licence | Subscription |
Read that table before you pay us anything. If you want a free, fully local EPUB reader that reads aloud with neural voices, Calibre does that and costs nothing. If your document is a PDF and you only need it once, Edge is already on your computer.
What you pay us for is the fourth row: listening to a book written in a language you do not read, translated as it is spoken. And if your documents are private, Speechify and NaturalReader’s online app need them on their servers first. We never receive them: the file stays on your device, the online voice receives only the sentence being read, and online translation, if you choose it, the passage; with confidential documents, do not use online translation. Calibre reads entirely on your computer.

Frequently asked
Common questions about Auris Reader
Is there a free trial?
Yes. The Starter plan includes a 14-day free trial. We collect your payment method at sign-up so the subscription auto-renews on day 15 — Starter is €4.99/month (or €49/year) for up to 2 documents per day. Pro and Premium plans, for heavier daily use, are coming soon. Cancel anytime before day 15 to avoid any charges. If you have already had a free trial, the subscription starts without one, and you see the amount and the date of the first charge before you confirm.
Does it work without internet?
Partly. The neural voices are generated online, so reading aloud needs a connection; if it drops, the app switches to the voice installed on your device on Windows and Android, and stops on Linux. Your books are never uploaded — only the sentence being read is sent. Translation can also work offline, in every plan: on desktop for some language pairs with English, each downloaded the first time you need it, and none yet with German or Dutch; the Android app downloads each language once and then translates on the device. You can stay offline for up to 7 days before the app needs to check your subscription again.
Which file formats are supported?
EPUB 2, EPUB 3 and PDF. Auris Reader works with DRM-free files and reads the text layer inside a PDF, so digital PDFs and scans that already contain text work. Its adaptive cleaner filters headers, footers and artifacts so the voice reads the actual content, not the noise.
Which languages can I read in?
Auris Reader ships with 8 neural voices in Spanish and English, and free downloadable voice packs add French, German, Italian, Portuguese (Portugal and Brazil), Dutch, Polish, Swedish, Romanian, Bulgarian and Hungarian — over 20 voices in 12 languages, each with a male and a female option. The app interface is available in English and Spanish, with free French, Italian, German and Portuguese interface packs. Online contextual translation, if you choose it, supports 50+ languages, and offline translation is included in every plan: on desktop it covers 15 language pairs, all to or from English.
Do my books get uploaded anywhere?
No. Your EPUB and PDF files stay on your device, on desktop and on Android. To read aloud, the neural voices receive only the sentence being spoken; online translation, if you choose it, receives the passage being translated. Never the file, never your library, and nothing about which book you are reading.
Which platforms are supported?
Windows 10 and 11 (signed installer), and Linux (.deb for Debian/Ubuntu). The Android app is available on Google Play. There is no iOS version yet.
How do I cancel?
From your account, at any time — no phone call, no retention offers. Your subscription stays active until the end of the period you already paid for, and you will not be charged again. Your account and your local library stay, so you can re-subscribe later. Deleting your account is a separate action.
What happens to my data if I close my account?
Closing your account cancels your subscription and starts a 30-day window in which you can export all your data or reactivate the account. After 30 days we delete your account and its operational data. Invoices are kept for as long as the law requires. The library files on your device are always yours.
Can I download the audio as an MP3?
No, and that is a design decision. Auris Reader plays your books live instead of converting them: that is why you can change the voice or the language in the middle of a chapter and carry on from where you were, instantly and with nothing to re-generate. An exported file would freeze both choices, and we chose not to add one. If what you need is a file for the car, an EPUB-to-audiobook converter is a different tool for a different job.
