聽閱 ReadAloud

Turn any text into a hands-free audiobook. ReadAloud reads EPUB, PDF, and TXT files in Cantonese, Mandarin, or English using Apple's high-quality on-device voices — perfect for commuting, exercising, or resting your eyes.

READING + LISTENING, TOGETHER

Two reading modes that adapt to how you want to consume content: • Voice + Reading — see the full text with the current sentence highlighted as it's being read. • Listen-Only — distraction-free karaoke view showing the previous, current, and next sentences in large text. Ideal for closing your eyes and just listening.

SUPPORTED FORMATS

• EPUB (2 & 3) — automatic chapter detection • PDF — text extraction with chapter inference • TXT — plain text with smart chapter splitting • Clipboard — paste any article instantly

MULTILINGUAL VOICES

Switch between three voice languages — each remembers its own speed: • Cantonese (zh-HK) — 阿成, 善怡, and more • Mandarin (zh-CN / zh-TW) — 冬梅 (Liaoning), 浩浩 (Shaanxi), 盼盼 (Sichuan), 美嘉 (Taiwan), and others • English (en-US / en-GB / en-AU / en-IN) — Samantha, Daniel, Karen, and any installed English voice The voice picker shows each voice's region in plain language so you know what you're picking.

TRADITIONAL — SIMPLIFIED

Built-in OpenCC engine converts between scripts at the word level — much more accurate than character-by-character mapping. Switch instantly without re-importing your book.

SMART READING EXPERIENCE

• Sentence-level highlighting that follows the voice • Auto-scroll keeps the spoken text in view • "Return to reading position" floating button when you scroll away • Tap-and-hold any text: Read from here / Add bookmark / Share • Search within books with jump-to-result • Auto-detected chapters with table of contents • Background audio: keep listening with the screen locked • Built-in sleep timer (15 / 30 / 45 / 60 / 90 min) with soft fade-out • Idle timer disabled during playback so the screen never blacks out mid-read

CUSTOMISE EVERYTHING

• Font size, line spacing, font family (serif, rounded, monospaced) • Three themes: dark, light, sepia • Orientation lock (auto / portrait / landscape) • Per-language playback speed • Voice gender preference (auto, male, female)

100% PRIVATE

ReadAloud was built around a simple principle: your reading is none of our business. • No accounts, no sign-up, no login. • No analytics, no tracking, no ads. • No data is ever sent over the network. • All books and progress stay on your device. Delete the app and everything is gone.

BUILT FOR CHINESE READERS

Many TTS apps cater only to Mandarin. ReadAloud is built by a Hong Kong developer with Cantonese readers in mind. Optimised tokenisation for traditional Chinese, comma-level phrase highlighting that keeps up with natural Cantonese rhythm, and a dedicated voice picker that surfaces "粵語 (香港)" voices first if your default is Cantonese.
