Read and listen to your own books in natural voices. Open EPUB, PDF, Kindle, Word files or comics, tap Listen and LaziBook reads to you — speech is generated right on your iPhone or iPad, with no internet and no ads. LISTEN • Tap Listen and reading starts from the page you are on; the current sentence is highlighted, each word lights up as it is spoken, and pages turn by themselves. Tap any word to read from there. • Keeps reading with the screen locked, with controls on the Lock Screen, Dynamic Island and headphones. • Background sound: 18 music themes, 12 ambient sounds (rain, a stream, campfire…), chapter intro and outro music. • A separate voice for dialogue, custom pronunciations for any word, and Speak for any selected passage. • Speed 0.75–2×, sleep timer and an Up Next queue. • M4B audiobooks: export each chapter as a file, gathered into an album per book; listen in the app, save or share. VOICES ON YOUR DEVICE • 30 Vietnamese voices from the North, Centre and South, each in two editions: Turbo, with expressive 48 kHz audio (iPhone 13 / SE 3 and later, iPads with A15 or M1), and Nano, light and battery-friendly on every device. LaziBook switches to the matching Nano voice when Turbo can't keep up. • 37 English and 6 Chinese voices. LaziBook picks the right voice for the language of each book and each sentence. • Studio: pauses, emotions, multi-voice scripts, MP3 with cover art. • Create your own voice from 5–8 seconds of recording — processed on your device, never uploaded. BOOKS THAT LOOK THE PART • Book effect with page edges, spine and pages that curl under your finger; two pages on a landscape iPad, or vertical scrolling. • Cover templates: 6 layouts, 8 styles, 6 palettes each — design a beautiful cover from your own picture; books without a cover get one that suits their genre. • Vietnamese spelling by context: 3,461 hand-reviewed error spots (two words either side) fix typos and OCR errors; tap a snippet to fix just that spot. • Clean Up & Convert: rewrite a book as a tidy EPUB 3 laid out like an edited edition — red chapter titles, a large initial, rebuilt contents; turn TXT, Word, Kindle and text PDFs into EPUB 3, or export an A5 PDF. • Six light and dark themes; highlights in five colours, notes, bookmarks and a Notebook; footnotes open in place. LOOK UP AND TRANSLATE • Look up a word or a whole passage with Lazidi (Vietnamese, English, Chinese, Japanese) or the built-in Dictionary. Pinyin and Sino-Vietnamese readings above Chinese characters. • Translate books into Vietnamese, English or Chinese on your device, in the style of the story: read side by side or listen to the translation; edit any sentence, keep a names list. One-time 440 MB download. PDFS AND COMICS • PDFs keep their original printed layout, with the current sentence highlighted on the page; scanned pages are recognized on your device and read aloud. • Comics in CBZ, CBR, CB7, CBT and PDF: right-to-left reading for manga, vertical scrolling for webtoons. LIBRARY • 15 formats: EPUB, PDF, MOBI, PRC, AZW, AZW3, DOCX, TXT, RTF, Markdown, FB2, CBZ, CBR, CB7, CBT. • Add books from Files, Google Drive, Dropbox, OPDS servers (Calibre, Komga, Kavita…), or paste a Wikisource, Project Gutenberg or story-site link; Free Books to listen right away. • Books live in iCloud Drive › LaziBook, shared with your iPad and Mac; progress, highlights, notes, covers and voices sync through iCloud — and, if you turn it on, through Google Drive with e-readers. • Quick Find, book status, smart shelves, reading and listening statistics with a daily goal; widgets and a Read button for Control Center. PRIVACY No ads, no tracking; account optional. Your books, notes and voices stay on your device and in your own iCloud or Google Drive; LaziBook only receives anonymous reading and listening time (no device ID, none of your titles). Note: DRM-protected books cannot be opened. Requires iOS 16.4; English voices need iOS 18. Translation needs an A13 chip and 4 GB of RAM.
