How to Convert EPUB to Audio: Turn Any Ebook Into an Audiobook

Your ebook library is already text — every EPUB you've bought or downloaded can become an audiobook without you doing anything except uploading it. Here's how to convert an EPUB to audio and start listening instead of reading.

Why Convert EPUB to Audio

Not every ebook has an official audiobook edition, and even the ones that do often cost extra or use a different narrator than you'd choose. Converting the EPUB yourself sidesteps both problems, and opens up a few practical benefits:

Listen while commuting, exercising, or doing anything that doesn't leave a hand free for a screen
Make books accessible if reading text for long periods is difficult or tiring
Finally get through the backlog of ebooks you've bought but never opened
Turn niche or self-published titles with no audiobook edition into one

Most ereaders and reading apps assume you'll sit and stare at a page, which is exactly the constraint audio removes. Once a book exists as audio, where and how you consume it stops being tied to a screen — the same chapter you were reading on your commute in the morning can keep going in your ears on a run that evening.

What Is an EPUB (and Why It Converts Well)

EPUB is a reflowable ebook format — the text is stored as actual text, not as an image of a page, so it can reflow to fit any screen size. That same property makes it ideal for text-to-speech conversion: the underlying text extracts cleanly, with no OCR guesswork involved. Compare that to a scanned PDF, where the "text" is really a photograph of a page, and the converter has to recognize the characters before it can read anything aloud. An EPUB skips that step entirely, which means fewer misread words and a cleaner listening experience.

Step-by-Step: Convert an EPUB on Say the Text

Create a free account — sign up at saythetext.com. No credit card required, and you get 50 free hours of conversion every month.
Upload your EPUB — open Create Audio and upload your EPUB file. PDF, DOCX, and TXT also work, and files up to 50MB are supported.
Choose a voice and language — pick a natural AI voice, or use a cloned voice, in any of 23 languages. You can preview a voice before committing to it.
Convert to audio — start the conversion. Long ebooks process in the background, so you don't have to sit and wait — the finished audio lands in your library as an MP3.
Listen anywhere — stream it in the browser with speed control, or download the MP3 to listen offline on any device.

Other Formats You Can Convert

EPUB isn't the only format Say the Text handles — the same workflow covers:

PDF — reports, papers, and ebooks distributed as PDFs
DOCX — Word documents and manuscripts
TXT — plain text files
Pasted text — anything you copy directly into the text box

If most of your library is PDFs rather than EPUBs, the process is identical — see how to convert a PDF to audio for the same walkthrough applied to that format, or read more on turning your whole digital library into audio.

Tips for the Best Audiobook Result

Pick a voice you actually enjoy listening to — preview a few before converting a long book; you'll be spending hours with this voice.
Try 1.25×–1.5× speed — most listeners find this range comfortable once they're used to audio, and it gets through a book faster.
Clone a voice for a consistent library — if you convert a lot of books, a cloned voice makes your whole audiobook collection feel uniform, and cloning is free.
Don't worry about book length — long books process in the background, so there's no need to split a novel into chapters before uploading.
Check the voice on a short sample first — convert the first chapter alone to confirm the pacing and tone work for that particular book before committing to the whole thing.
