NaturalReader vs Audible
NaturalReader: AI text-to-speech app for personal use that reads PDFs, documents, books, webpages and study materials aloud. Audible: Amazon’s audiobook store and membership: professionally narrated audiobooks and podcasts from its catalogue, rather than narration of your own files. Here is how they differ, and where Book2Speech fits if what you want is your books as audiobooks.
Choose NaturalReader if…
•
MP3 download of narrated text on every paid plan (1 million characters a month).
•
A pronunciation editor for correcting how words and names are read.
•
A free tier with unlimited listening using the free voices.
•
Voice cloning on Plus and Pro, and an OCR scanner for printed pages.
Choose Audible if…
•
Professionally narrated audiobooks from a very large catalogue, including Audible exclusives.
•
Premium membership includes thousands of titles in an all-you-can-listen catalogue plus a monthly credit.
•
Immersion Reading highlights the Kindle text as the narrator reads, when you own both editions.
•
Offline downloads, a sleep timer, and playback on Apple Watch, CarPlay and Alexa devices.
Or, for your books: Book2Speech
•
Any book, not just the bestsellers that got an audiobook: fewer than 1 in 100 books ever does.
•
Unlimited free listening in English with Standard voices, no trial clock.
•
A real audiobook file to keep: M4B with chapters and cover, or MP3. One is included on the Free plan.
•
Built for whole books: the book’s own chapters, a start past the front matter, page clutter left out of PDFs.
•
265 narrators in 42 languages, and 70,000 free classics ready to play.
•
Paid plans from $4.99 a month.
Notes on the comparison
Pricing shown in USD on 2026-10-07 from the vendor help centre; the US App Store also lists a Premium plan at $9.99/month or $59.99/year.
Formats from the App Store description: PDF, Word (.doc and .docx), PowerPoint, RTF, TXT, DRM-free EPUB and images. MOBI is absent.
Offline listening is through downloaded MP3 files (“listen offline”), a paid-plan feature.
The help centre mentions jumping to headings (Contents) but not chapter detection, so it is shown as not verified.
Prices in USD from the vendor membership page on 2026-10-07; the US App Store lists different in-app prices (e.g. Plus Monthly $7.99, Premium Plus Monthly $15.99, Annual $159.99).
Audible plays audiobooks published to Audible and has no text-to-speech for your own files: its pages describe narration made by authors and publishers, not listeners. Its AI-narrated “Virtual Voice” titles are produced by authors through Kindle Direct Publishing (US beta), not by listeners.
Amazon’s Kindle app (not Audible) can read Kindle-store books aloud with the device’s own voice through Assistive Reader.
Read & Listen requires both the Kindle ebook and the Audible audiobook of the same edition.
Audio file export, voice choice, pronunciation editing and a top playback speed are not stated on the fetched pages (the App Store says only “Adjustable playback speed”).
