About this extension
Lumen: English Pronunciation is your ultimate companion for mastering English speaking, reading, and accent reduction!

Have you ever looked at an English word and wondered how to pronounce it? With Lumen, you no longer have to guess. Lumen magically transforms the text on any webpage by adding clear, intuitive visual cues that guide your pronunciation in real-time. Whether you are an ESL student, a language learner, or someone wanting to refine your accent, Lumen is designed for you.

✨ Core Features:

Ghost Letters: Silent letters (like the 'w' in sword or 'k' in knife) are faded out so you know exactly what not to pronounce.
Color-Coded Vowels: Instantly recognize vowel sounds! For example, the /i/ sound in "receipt" is colored green, and the /æ/ in "cat" is pink.
Stress Accents: Learn the natural rhythm of English with automatic accent marks on stressed syllables.
Hidden Phonemes & Diphthongs: Get visual indicators for tricky sounds and diphthong glides.
Z-Sound & T-Sound Morphs: Underlines letters that make a /z/ sound (like the 's' in dogs) and shows a small /t/ when 'ed' makes a T sound (like in asked).
🌍 Translation & Dictionary Integration:

Instant Translation: Hover over any highlighted word to instantly see its translation. Supports over 100 languages!
Per-Sentence Translation: Select an entire sentence to translate contextually on the fly.
Built-in Dictionary: Look up any word in our comprehensive pronunciation dictionary directly from the extension options.
📺 Video Subtitle Support:

Works seamlessly with video closed captions (CC). You can even set the video to pause automatically when you hover over a word to study its pronunciation.
⚙️ Highly Customizable:

Turn specific phonetic rules on or off to match your learning level.
Whitelist or blacklist specific websites so Lumen only runs where you want it to.
Sync your preferences across all your devices by signing in securely with your Google Account.
💡 Why Install Lumen? Traditional dictionaries interrupt your workflow. Lumen brings the dictionary to you, embedding pronunciation directly into the articles, blogs, and subtitles you are already reading. It builds your muscle memory, improves your reading speed, and helps you speak English more confidently and naturally.

Install Lumen today and illuminate the path to perfect English pronunciation!
