Auris Reader features
Three adaptive engines.
One quiet reader.
Auris Reader is a text-to-speech EPUB and PDF reader with real-time contextual translation — built around three engines that adapt to every document you open.
Available for Windows and Linux, with Android on Google Play.
Adaptive engine 01
Adaptive Predictive Pipeline
Speech that flows. The pause between sentences disappears.
Most text-to-speech readers synthesize one sentence at a time: the voice stops, the next request goes out, and you hear the seam. Over a chapter, those gaps add up to listening fatigue.
Auris Reader measures two speeds — how fast the voice engine generates audio and how fast you are listening — and pre-generates the next sentences in the background. The buffer grows and shrinks on its own, so the reading keeps flowing through long paragraphs, dialogue and dense pages alike. There is no setting to configure.
- The next 3–5 sentences are buffered before you need them
- Jump back one sentence without breaking the flow
- Your reading position is remembered per book, across sessions
Adaptive engine 02
Contextual Translation Memory
Translation that remembers who is who.
Translate a novel sentence by sentence and the cracks show fast: a character called Hope becomes the word “hope”, technical terms drift between synonyms, pronouns lose their owner. Generic translators have no memory of the page before.
Auris Reader translates with a sliding context window: each sentence goes out together with the three before it, so the translator knows what it is continuing. Proper names are remembered as you read and keep the translation they got the first time, so a character or a place does not change name from one page to the next. Translation runs alongside the voice, so you can listen in one language while reading in another.
- Sliding context window across sentences and paragraphs
- Proper names keep the same translation from page to page
- Offline translation included in every plan, in 15 language pairs; online, from 50+ languages
Adaptive engine 03
Adaptive PDF Content Detection
PDFs without the noise.
Academic papers and technical PDFs are full of things you never want to hear: running headers, page numbers, watermarks, URLs. Ordinary readers speak all of it.
Auris Reader analyzes the layout of each document and builds a per-document profile of what is content and what is furniture. It reads the opening pages to learn what repeats, then filters headers, footers and page numbers, and stops a pull quote from cutting through the paragraph beside it. The profile comes from the document in front of it rather than from a fixed list of rules, which is what lets it cope with a layout it has never seen.
- Running headers, footers and page numbers stay silent
- Pull quotes stop interrupting the paragraph
- The profile is built from the opening pages of each document
And around the engines
Everything a daily reader needs.
Voices and languages
Over 20 neural voices in 12 languages, with a male and a female voice for every language. Spanish and English are ready out of the box with Spain, Mexico, US and UK accents; French, German, Italian, Portuguese (Portugal and Brazil), Dutch, Polish, Swedish, Romanian, Bulgarian and Hungarian arrive as free downloadable voice packs.
- The voice you pick sets the language it reads in
- Offline fallback voice on Windows
- More voice packs on the way
Reading experience
The highlight follows the voice sentence by sentence, so your eyes can follow along or rest. Open a book and you are back on the exact sentence where you stopped.
- Synced highlight while the voice reads
- EPUB 2/3 and PDF
- Per-book position memory
Private by design
Your books stay on your device. The app does not track what you read, and your account exists only to manage your plan and your devices.
- Library and reading history stay local
- No ads, no data sales
- Windows 10/11 and Linux (.deb)
