Formats and what LuceVoce does with them

Format Files What LuceVoce does
EPUB .epub, .kepub EPUB 2 and 3 in reading order. Chapters from the book's contents, drop caps and captions kept as printed, the book's page list used as page numbers, footnote numbers shown but not read, the cover and details taken for the library.
PDF .pdf Text put in reading order from the page layout: columns, tables read row by row, headings by size. Repeating headers, footers and page numbers are removed, a sentence that runs over to the next page is read as one, and words stuck together are split. The PDF's page labels become page numbers. Scanned pages are read with text recognition. You can also see the real pages. See Read PDFs.
Kindle .mobi, .azw3, .azw, .prc MOBI and AZW3 (KF8) books, with their details and contents.
Word .docx Heading styles, numbered lists, tables, footnotes and endnotes (read at the end). Tracked deletions are skipped.
Word 97-2003 .doc Text with headings, lists and tables.
OpenDocument text .odt Headings, lists and tables.
Rich Text .rtf Headings, lists and tables.
PowerPoint .pptx Each slide read as a heading with its text, and its speaker notes after it.
FictionBook .fb2, .fbz Sections as chapters, notes, the cover and the title details. Works with Cyrillic files in windows-1251 too.
Web pages .html, .htm, .xhtml, .mht, .mhtml Saved web pages with headings, lists, tables and figures. Menus, scripts and styles are left out.
calibre .htmlz, .txtz calibre's zipped web page and text books, with their details and cover.

Markdown .md, .markdown Headings, lists, quotes and code blocks shown as such.
Comic books .cbz, .cbr, .cb7 Each picture is a page. The words are found with text recognition, as for a scanned PDF, in the background from the page you are reading, and speech balloons are read as short paragraphs. The comic opens on its pages, with the spoken word lit on the picture; Show the text and Show the pages switch between the two. The title, writer, series, language and summary come from the archive when it has them. An archive protected by a password can't be opened.
DAISY .zip DAISY 2.02 and DAISY 3 talking books, with their text: headings, lists, lines, and figures with their description. The printed page numbers become page numbers and are not read aloud. A DAISY book with recorded audio only, and no text, can't be read.
Help files (CHM) .chm On Windows only. The pages in the order of the help file's contents, each read as a web page. The Mac, iPhone and iPad don't read CHM files.
Audiobooks .mp3, .m4b, .m4a, .aac, or a folder of numbered tracks Played in the listening view with title, cover, chapter, position, length and volume. Chapters, the cover and the narrator come from the files. Speed from 0.5x to 3x without changing the pitch, sleep timer, and resume where you stopped.

Add a book in any of these formats

Select Add in the library and pick the file, or drop it on the window on Windows and Mac. On iPhone and iPad you can also share the file from another app and choose LuceVoce. To add many at once, scan a folder: see Scan a folder for books and watch it.

Listen to an audiobook

  1. Open the audiobook from the library. The listening view shows its cover, chapter and time left.
  2. Use the bottom bar as for any book: play, skip back and forward, previous and next chapter, speed and sleep timer.
  3. Open Contents for the list of chapters with their start times, and select one to play from there.

Audiobooks get their own Audiobooks view in the library rail. To find them in a search, type kind:audio.

Good to know

  • Books with copy protection (DRM) from Kindle, Apple Books, Kobo, Adobe or Audible can't be read. LuceVoce recognises them and tells you so. See Books protected by DRM.
  • Web articles can also be saved straight from their address. See Save web articles and use the Reading List.
  • Older Kindle PRC and AZW files open when they have no DRM.
  • Pictures inside MHT and FB2 files are not shown. Old .doc files show no pictures or headers.
  • A folder of short songs is treated as music and is not added as an audiobook.
  • Comic pages are read with the same text recognition as scanned PDFs. On Windows it needs a text recognition language for the comic's language. See Listen to scanned PDFs.
  • Add a DAISY book as the zip it came in. An unzipped DAISY folder is not added.
  • DjVu files are recognised but not read; a scan lists them under Not supported yet.
  • A scan does not pick up web pages, PowerPoint files, help files (CHM) or DAISY books (ZIP); add those with Add.
