Lumen: English Pronunciation

Lumen: English Pronunciation is your ultimate companion for mastering English speaking, reading, and accent reduction! Lumen overlays pronunciation guides directly onto any webpage so you never have to leave what you're reading to look up a word. Silent letters fade out, vowel sounds light up in color, and stress marks appear automatically — turning every article, blog post, and subtitle into a pronunciation lesson. Perfect for ESL students, accent learners, and anyone who wants to speak English more naturally. 🔤 Pronunciation at a Glance • Ghost Letters — Silent letters fade out (the k in "knife", the w in "sword") so you know what not to say. • Color-Coded Vowels — Each vowel sound gets its own color: green for /iː/ in "receipt", pink for /æ/ in "cat", and more. • Stress Marks — Accent marks appear on stressed syllables so you learn the natural rhythm of English. • Hidden Sounds & Diphthongs — Visual cues for tricky phonemes and vowel glides you might otherwise miss. • Z-Sound & T-Sound Morphs — Underlines the s that sounds like /z/ (as in "dogs") and flags the -ed that sounds like /t/ (as in "asked"). 🌍 Translation & Dictionary • Hover to Translate — Point at any highlighted word to see its translation instantly. 100+ languages supported. • Sentence Translation — Select a sentence to get a full contextual translation on the spot. • Built-in Dictionary — Look up pronunciation and definitions without leaving the page. 📺 Video Subtitle Support • Works with closed captions on YouTube and other video sites. • Optional auto-pause: the video pauses when you hover a word, giving you time to study it. ⚙️ Fully Customizable • Toggle individual phonetic rules to match your level. • Whitelist or blacklist sites — Lumen runs only where you want it. • Sign in with Google to sync settings across all your devices. 📚 Word Library & Flashcards • Save words to your personal library with one click. • Review saved words with IPA, translations, and example sentences. • Export to Anki for spaced-repetition study.
