Murmur: EPUB & PDF Reader
AI Text to Speech & Read Aloud
Only for iPhone
Free · In‑App Purchases
iPhone
Turn the books and documents you already own into audiobooks.
Murmur reads EPUBs and PDFs aloud with natural neural voices that run entirely on your iPhone. Import a book, choose a narrator, press play, and keep listening while you commute, exercise, cook, clean, or simply give your eyes a break.
NO AUDIOBOOK? NO PROBLEM.
Most books will never receive a professionally produced audiobook. Your textbooks, PDFs, self-published books, research material, old EPUBs, and personal documents may never have one at all.
Murmur lets you listen to the files you already have instead of buying another copy.
READ EPUB & PDF ALOUD
Import EPUB and PDF files directly into your library. Murmur organizes books into chapters and paragraphs and keeps your reading and listening position together.
Follow the text while the narrator speaks, or put your phone away and keep listening in the background.
23 NEURAL VOICES
Choose from 23 bundled narrators across 10 languages.
Set a default narrator for each language or choose a different voice for an individual book. Adjust playback speed whenever you want.
PRIVATE AND OFFLINE
Your books stay on your iPhone.
Speech is generated on-device, so Murmur doesn't need to upload your EPUBs, PDFs, textbooks, or personal documents to a text-to-speech server.
