We’ve made big changes to the Chrome OS screen reader known as “ChromeVox.” ChromeVox comes built-in with every Chromebook, and These changes are the result of important feedback from our ChromeVox users (and other lessons learned over the years). For now, the older version, now called “ChromeVox Classic” (“Classic” for short), will still be available, but because we’re so sure you’ll like this new experience, it won’t be for too long.
ChromeVox announces which version you’re using and what currently has focus. You might also be able to tell because the earcons (sound effects) are different. Why we did this
The Classic version of ChromeVox worked partly by running inside every web page you visit. ChromeVox could easily interact with web pages and faithfully convert the full web experience into speech and braille. But this design also had many challenges, like accessing some controls and working the same way when you weren’t in a web page. ChromeVox now runs separately and interacts with the entire screen so ChromeVox can deliver a consistent, fast experience no matter what you're doing. ChromeVox works identically to other screen readers and assistive technology on other platforms. Chrome increasingly supports ARIA and other web standards, so that you get the same accessibility experience on all platforms whether using ChromeVox or any other tool.
