NextPhase Reader vs Natural Voice Reader

Read it. Listen to it. Learn from it. Listen instead of read. Turn your documents and compatible books into audio. NextPhase Reader brings reading, listening and language practice together on iPhone and iPad, using content you choose. LISTEN TO YOUR CONTENT • Read supported books and documents aloud using Apple device voices by default, with voice, speed and sleep-timer controls. Optional online voices are also available for live listening. • Listen to the original text, its translation, or both. • With Pro, prepare chapters or PDF pages as saved audio for offline playback. Export separate M4A recordings to Files or share them with another app. • Create saved audio with downloaded Kokoro voices, on your device with the app in the foreground. Apple device voices and online voices are for live listening; online voices require an internet connection. READ WHAT INTERESTS YOU • Import your own DRM-free EPUB, KEPUB, PDF, MOBI, AZW3, FB2, TXT, RTF, DOCX and HTML files. • Explore free classics through Project Gutenberg and Standard Ebooks, or connect a compatible OPDS library. • Adjust text size and reading layout, choose Light, Sepia or Dark, and keep highlights, notes and bookmarks. • Read text-based PDFs in their original layout or as flowing text. Scanned PDFs without selectable text are not supported for translation or speech. LEARN FROM YOUR READING Stay motivated. Read in the languages you want. Import content for side-by-side reading. • Read original and translated EPUB paragraphs together: side by side on wider screens, interleaved on narrow screens. • Save words in context and return to them with spaced-repetition review. • Use pronunciation guides for supported languages, including pinyin, furigana and romaja. • With Pro, highlight saved words as they reappear, export vocabulary as CSV, and export compatible books as bilingual EPUBs. Your first vocabulary CSV export is free. TRANSLATION CHOICES Built-in online translation needs no API key. Apple on-device translation requires a supported device, OS and downloaded language pair; unavailable language packs may lead to an online fallback. You can also use your own DeepL, OpenAI, Google Cloud or Azure key. Provider availability and quality vary by language. Completed translations are cached for reuse. PRO: ONE-TIME PURCHASE Choose one book to try Pro features free. Unlock Pro for all your books with a one-time in-app purchase for major version 1. No subscription. Pro includes natural voice downloads, saved audio, bilingual EPUB export and vocabulary export. Family Sharing is supported. Restore purchases is available in Settings. YOUR CONTENT, YOUR CHOICES Core reading works without an account. Your library is stored locally. Online translation and speech send relevant text to the selected services; optional account sync uploads reading data. Downloaded voices and saved audio support offline listening, but online services and new downloads require a connection. Compatible, DRM-free content only. Audio exports are separate chapter or page recordings, not a single combined audiobook. Interface available in English and Spanish.

Listen to your text and follow along with word highlighting. Natural Voice Reader keeps your readings, recordings, and listening position together in a simple library. SIRI EXPRESSIVE VOICE Paste text or import a text file, then prepare narration with an expressive Siri voice through Apple Shortcuts. Save the audio to listen again without generating it each time. PLAYBACK THAT FITS YOUR PACE Pause and resume, change playback speed, jump back or forward 10 seconds, and set a sleep timer. Tap a word to listen from there. Spoken words are highlighted, and the page moves forward when you reach the bottom. Continue listening with Lock Screen controls. YOUR READING LIBRARY Search your readings, mark favorites, and pick up where you left off. Start with the included short story, The Quiet Hours, or add your own text. IMPORT AND SHARE Import M4A, MP3, WAV, or AIFF audio and create an English transcript on your device when local speech recognition is available. Export a recording as M4A, or share a .naturalreading file containing its audio, text, and word highlighting. Shared readings play on iOS 18 or later without setting up a voice or generating speech again. ALL FEATURES ARE FREE No account is required. Optional one-time tips support the app and do not unlock any features. There are no subscriptions or ads. DEVICE REQUIREMENTS Creating new Siri narration in this app requires iOS 27 or later, Apple Shortcuts, a compatible expressive Siri voice, and on-device English speech support. Voice availability depends on your device, language, region, and Apple's services. Setup guides you through installing and checking the shortcut. On iOS 18 or later, you can play saved or shared readings. Transcribing an imported recording requires an available on-device English speech model. A shared .naturalreading file already includes the text and timing, so playback does not require a speech model. Your library stays in the app's storage on your device. The app does not upload your library to a developer server or include developer analytics. Siri narration uses Apple Shortcuts; Apple services have their own privacy practices.
