About this extension
The extension supports offline speech using the voices available in the user's browser and device. It can also use Google Cloud Text-to-Speech for online speech synthesis, including supported English (India) neural voices.
Key features:
• Read webpage text aloud with sentence-by-sentence highlighting.
• Read supported PDF documents aloud.
• Automatically highlight the sentence currently being spoken.
• Pause, resume, stop, and control speech playback.
• Use available browser/device voices for offline reading.
• Optional Google Cloud Text-to-Speech support for higher-quality online voices.
• Supports English-India voices when available through Google Cloud.
• Designed to make reading webpages and documents easier and more accessible.
The extension is intended for students, readers, researchers, and anyone who prefers listening to digital content instead of reading it manually.
Offline speech does not require an internet connection when a suitable browser/device voice is available. Google Cloud Text-to-Speech features require an internet connection and the necessary Google Cloud configuration.
SentenceTTS Reader only processes the text required for speech playback and provides users with control over how content is read aloud.
