FAQ
Do I need to install a real screen reader?
No. AccessibilityDevHelper runs entirely in your browser and simulates screen reader behavior using the Web Speech API and DOM inspection — no external software required.
Which browsers are supported?
Chrome, Edge, and Firefox on desktop are fully supported. Audio feedback requires a browser with Web Speech API support (Chrome and Edge recommended).
Can I test any website, or only my own?
You can test any URL you have access to. For best results on third-party sites, use our browser extension to inject the simulator directly into the page.
