Hear the book, not the page furniture
Most read-aloud tools read everything printed on a page, so a sentence gets cut in half by a running header or a page number. DocuVocal looks at the whole document before it reads. It removes lines that repeat at the top and bottom of every page, drops page numbers, rejoins words that were split with a hyphen at the end of a line, and carries a sentence across a page break. Reference lists at the end of papers are skipped by default.
A voice you can listen to for an hour
Your browser voice starts instantly. For longer listening, switch on the natural voice: a modern AI voice that downloads once (about 90 to 330 MB, depending on your device) and then runs on your own computer or phone. You can slow it down to 0.5× for difficult material or speed it up to 3× for skimming, and jump back or forward one sentence or one paragraph at a time.
Scanned PDFs work too
If your PDF is a scan with no selectable text, DocuVocal offers to read it with text recognition (OCR). It is slower than a normal PDF because every page has to be recognised first, but you can start listening as soon as it finishes.
