Bring your ebook and audiobook together. Switch seamlessly between reading and listening, with the text following your narrator and your place kept in sync. Your ebook. Your audiobook. One place in the story. Bring both versions of a book to Unison Reader and move seamlessly between reading and listening. Follow your audiobook's narrator in the text, word by word, then pick up reading where you left off. READ AND LISTEN TOGETHER Add your audiobook to its matching ebook. Unison Reader aligns the narration with the text on your device, so you can listen, read along, or switch between the two without hunting for your place. START WITH WHAT YOU HAVE Only have the ebook? Choose a voice generated on your device to read it aloud. Only have the audiobook? Unison Reader can generate text from its narration. These options help you read and listen even when you do not have both versions. YOUR BOOKS, YOUR LIBRARY Import EPUBs, PDFs, Word documents, plain text, Markdown, HTML, and other supported book files. Browse Project Gutenberg and Standard Ebooks, or download books and audiobooks from your own supported library server. MAKE READING COMFORTABLE Choose a paged, scrolling, or caption layout. Adjust appearance, listening speed, word emphasis, and how the text follows the voice. Save highlights and bookmarks, look up words, and adjust pronunciations. AT HOME ON YOUR DEVICES Sync your library through your own iCloud account when iCloud Drive is available. Speech generation and audiobook alignment happen on your device. Generated audio is prepared while Unison Reader is open; prepared audio continues playing with the screen locked. TRY LISTENING Reading is free. One hour of listening in step with the text is included. A one-time in-app purchase unlocks continued listening with your own audiobook or a generated voice. No subscription. Bring your own book and audiobook files; commercial titles are not included.
