Does text to speech word highlighting work, or only sentences?

VoiceRead highlights by sentence today, which keeps the page calm at reading speed. Word-level highlighting is coming soon.

Can I listen and read along with my own PDF or ebook?

Yes — any file you open in VoiceRead gets the same highlighting, including PDFs, EPUBs, DOCX and scanned pages.

Can I export the subtitles without the audio?

Not on their own yet. The .srt file is exported together with a Studio voiceover on the Pro plan. In the reader, every sentence is highlighted as it's read.

Highlighting is part of the reader for every user. Standard voices are free; premium voices and unlimited downloads come with Pro. See pricing.

Chapter 4 · The night shiftEPUB · 37% LISTENED

Most of us treat sleep as time off. For the brain, it's closer to a night shift.

While you sleep, the brain replays parts of the day and moves what matters into longer-term storage. Skip that step, and new information is harder to hold on to.

That's why a short review before bed can help, and why an all-nighter before an exam often backfires.

WHY SEEING THE WORDS MATTERS

Immersive reading: eyes and ears on the same sentence.

Reading while listening keeps attention on the page and makes it easier to remember what you heard. For readers with dyslexia or ADHD it's often the difference between finishing a chapter and giving up on it.

Sentence-level highlighting, not a whole paragraph — your eye always knows where the voice is.
Adjustable text size and a dark reading surface that stays easy on the eyes at night.
Notes pinned to the sentence, so you can come back to the exact spot later.
