A research paper is not written for the ear. The title page lists authors and affiliations, every claim carries a bracket citation, and tables and code listings interrupt the prose. Reading it aloud literally makes a paper harder to follow.
Research paper mode is an optional listening mode built for this problem. It keeps the parts that carry the argument and leaves out the parts that are mainly visual or bibliographic.
What stays in the audio
- The paper title and abstract.
- Section headings, including numbered headings.
- The running prose, in reading order.
- Normal numbers and parentheses, so “2026”, “34.50” or “Figure 2 shows” are not mistaken for citations.
What is left out
- Authors, affiliations and email addresses on the title page.
- References and bibliographies.
- Acknowledgments and appendices.
- Tables, table titles and dense numeric rows.
- Code listings and monospace blocks.
- Figures and figure captions.
- Repeated headers, footers, page numbers and footnotes.
- Dense formula-only lines and stray symbols.
- Inline citation markers such as
[27],[27, 28], author-year citations and superscript reference numbers.
This filtering happens before narration. It does not delete the original document or rewrite its meaning.
How to use it
- Upload a text-based PDF on the converter and wait for the document check.
- Review the extracted text. If the PDF contains images or charts, confirm that you want the readable text narrated.
- Turn on Research paper mode on the review page.
- Look at the read-only preview, which shows the filtered text for the current page. The removal list groups what was left out by type and page.
- Save the mode to create a new text version, then preview or generate the audiobook.
The mode is off by default. Turn it off again to edit the full extracted text; previously generated tasks keep the version they were created with.
A listening mode, not a rewrite
The mode is deterministic. It classifies document regions and text lines using layout, typography and section patterns, then applies fixed filters. It does not send the paper to an AI rewriting service, and it does not paraphrase content.
That choice is deliberate: a listening tool should make the document easier to hear without inventing a new one. Unknown structure is kept rather than silently deleted, and anything that looks wrong can be corrected in the full-text editor.
Where it works — and where it does not
Research paper mode is available for PDFs with a usable text layer. Scanned papers can still be converted with page-by-page OCR, but the paper-specific classification is not applied there. Two-column papers are reordered into reading order; three-column or otherwise unreliable layouts are flagged instead of being guessed.
It is also heuristic. Different publishers use different title-page designs, section names, caption styles and table layouts. A table can be missed, a caption can be mixed into a body line, or an unusual section may not be recognized. The read-only preview and the removal list exist so that you can check before committing.
Before you rely on it
Listen to the preview, especially if the paper contains tables, equations or unusual front matter. When accuracy matters, compare it with the paper’s own text. The current limits cover supported formats, file sizes, page counts, languages and delivery.
