聽閱 ReadAloud

Turn any text into a hands-free audiobook. ReadAloud reads EPUB, PDF and TXT files aloud in Cantonese, Mandarin or English, with the sentence being spoken highlighted as you go. Perfect for commuting, exercising, or resting your eyes.

READING + LISTENING, TOGETHER

• Voice + Reading — the full text, with the current sentence highlighted as it is read.
• Listen-Only — a large, distraction-free view of the previous, current and next sentence.

SUPPORTED FORMATS

• EPUB — automatic chapter detection
• PDF — text extraction with chapter inference
• TXT — plain text in UTF-8, Big5 or GB18030, with smart chapter splitting
• Clipboard and Share — paste an article, or share text to ReadAloud from any app

VOICES

Uses the high-quality on-device voices of Google Text-to-Speech:
• Cantonese (Hong Kong) — five voices, female and male
• Mandarin (Mainland China and Taiwan)
• English
The first time you use a language, your phone downloads its voice once; after that, listening works offline.

TRADITIONAL — SIMPLIFIED

Built-in OpenCC conversion at the word level, far more accurate than character-by-character mapping. Switch instantly without re-importing your book.

SMART READING EXPERIENCE

• Sentence highlighting that follows the voice, with auto-scroll
• Keeps playing with the screen off, with controls on the lock screen and in notifications
• Pauses for calls and navigation prompts, then carries on
• Bookmarks, search within a book, table of contents
• Fix how a word is pronounced, and it stays fixed
• Sleep timer with a soft fade-out
• A free bookshelf of public-domain books to download

CUSTOMISE

• Font size, line spacing and font
• Dark, light and sepia themes
• Playback speed per language
• Interface in English, 繁體中文 or 简体中文

100% PRIVATE

• No accounts, no sign-up, no login.
• No analytics, no tracking, no ads.
• Nothing you import, read or listen to is sent anywhere. Books and progress stay on your phone.
• The app itself only uses the network when you open the free bookshelf and choose a book.

BUILT FOR CANTONESE READERS
