ChromeVox

ChromeVox is an open-source screen reader developed by Google, built as a Chrome browser extension and serving as the default screen reader for Chrome OS (Chromebooks). Unlike traditional screen readers that rely on operating system accessibility APIs, ChromeVox communicates directly with web applications through the HTML Document Object Model (DOM), which gives it unique capabilities for handling complex web content including mathematical notation. ChromeVox pioneered features like interactive formula exploration and customizable speech rules for mathematical content.
