What it does
Three things no other reader does together.
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.
Spanish neural voices, no compromise
Listen to EPUB and PDF books with natural-sounding neural voices. Spanish ready out of the box (Spain and Mexico accents), with more languages rolling out throughout 2026. Adjust speed without pitch artifacts and keep your place across sessions.
- EPUB 2/3 and PDF, including multi-column scientific
- Adjustable speed, pitch and pause length
- Predictive pre-buffering, no gaps between sentences
Contextual translation as you listen
Translate your reading in real time without losing context. Auris Reader remembers character names, technical terms and ongoing references with a sliding-window memory that keeps translations consistent across chapters.
- 50+ languages, with offline packs coming in 2026
- Persistent entity glossary per book
- Translates while the TTS keeps playing
Adaptive PDF cleaning
Read complex PDFs without garbled output. Auris Reader detects headers, footers, columns and footnotes automatically, so the voice reads what you would actually read — not the page numbers, not the metadata, not the artifacts.
- Multi-column scientific papers
- Footnote re-ordering on the fly
- Hyphenation and line-break repair
The highlight you hear
The line glows the instant the voice reaches it.
Every word 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 accounts to start, no cloud upload, no DRM headaches. Open a book on your computer and press play. That is it.
Open your file
Drop any EPUB or PDF into Auris Reader. Files never leave your device unless you explicitly enable online voices.
Pick a voice
Choose between Spanish neural voices from Spain or Mexico, or stick with the default. Adjust speed to taste. More languages rolling out throughout 2026.
Listen and translate
Press play. The highlight follows the voice in real time. Toggle translation on the fly to hear and read in another language at the same time.
Made for serious readers
“Your library, your pace, your language — without sending a single page to anyone’s servers.”
Why Auris Reader
The only reader that does all of this in one place.
Most TTS apps stream from the cloud and stop at reading aloud. Auris Reader adds contextual translation, adaptive PDF cleanup and a library that never leaves your device — all in one app.

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, arrive in 2026. Cancel anytime before day 15 to avoid any charges.
Does it work without internet?
Auris Reader uses high-quality online neural voices by default, with a built-in offline fallback voice on Windows when the connection drops. Your books are never uploaded either way — with online voices, only the sentence being synthesized is sent. Downloadable offline translation packs are on the 2026 roadmap.
Which file formats are supported?
EPUB 2, EPUB 3 and PDF — including multi-column scientific PDFs. 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?
Over 50 languages for reading and over 300 neural voices. Translation supports the same languages and currently runs online; downloadable offline translation packs arrive throughout 2026, starting with English, Spanish, French, German, Italian and Portuguese.
Do my books get uploaded anywhere?
No. Auris Reader is a desktop app: your EPUB and PDF files stay on your device. The only outbound traffic is the audio request to Microsoft Edge TTS (if you enable online voices) and an optional license check — never the content of your books.
Which platforms are supported?
Windows 10 and 11 (signed installer), and Linux (.deb for Debian/Ubuntu). An Android app is on its way to Google Play. There is no iOS version yet.
