Basic Text-to-Speech — Razmik

Press the toolbar button on any article and Basic Text-to-Speech reads it aloud.

• A natural voice that runs on your computer. It uses Piper, an open-source neural voice, inside the add-on itself. The page you are reading is never sent anywhere.
• Follow along. Each sentence is highlighted as it is read, and the page scrolls with it.
• Reads the article, not the clutter. Menus, ads, sidebars, share buttons and reference lists are skipped.
• Simple controls. A small bar on the page lets you pause, skip & change speed. Drag it anywhere; it fades out of the way while reading.
• Right-click to choose. "Read selection aloud" reads just the text you selected; "Read from here" starts at the sentence you clicked.
• Six English voices to choose from in Settings.

About the voice download. The first time you read, the voice (about 60 MB) is downloaded once from Hugging Face and kept in Firefox. That is the only thing this add-on downloads, and nothing is ever uploaded.

Not supported: PDFs (Firefox does not allow add-ons inside its PDF viewer) and Firefox's own pages.

Basic Text-to-Speech is free and open source (GPL-3.0). If you find it useful, you can support its development with the Contribute button on this page — every feature stays free either way.
