A TTS (Text-to-Speech) Reader with word highlighting is an online tool that converts written text into spoken audio while visually highlighting each word as it's being read aloud. This synchronized visual and audio experience helps improve reading comprehension, assists language learners, supports individuals with dyslexia or reading difficulties, and makes content more accessible for everyone.

Word highlighting creates a multi-sensory learning experience by combining visual tracking with auditory input. Research shows that simultaneous highlighting helps readers maintain focus, improves word recognition speed, strengthens the connection between written and spoken language, and significantly benefits English language learners, children learning to read, and individuals with ADHD or dyslexia.

Yes! This TTS Reader with word highlighting is completely free to use with no registration required. All processing happens locally in your browser using the Web Speech API—no text is ever uploaded to any server. You can adjust reading speed, choose from multiple English voices, switch between light and dark mode, and import text files, all without any cost.

This tool works on all modern browsers that support the Web Speech API, including Google Chrome, Microsoft Edge, Safari (macOS/iOS), and Firefox. It is fully responsive and optimized for desktop, tablet, and mobile devices. For the best experience with the widest voice selection, we recommend using Chrome or Edge on desktop.

Absolutely! You can choose from all available English voices installed on your system—including US, UK, Australian, and Indian English variants. The reading speed is fully adjustable from 0.4x (very slow, great for learners) to 2.2x (fast, for speed listening). You can also adjust the volume independently and change the font size for comfortable reading.

This TTS Reader is an excellent language learning companion. Try these techniques: (1) Listen and read along at a slower speed to improve pronunciation; (2) Pause and repeat challenging words by clicking on them; (3) Import English articles or stories to practice extensive reading; (4) Use the sentence-level highlighting to understand natural phrasing and intonation patterns; (5) Gradually increase the speed as your comprehension improves.
