We are concerned about accessibility on our web site and would like to see how it is perceived and decoded by a common screen reader?
回答1:
No. At least not one that is any good nor represents how a screen reader actually reads a page or responds to ARIA.
The best answer is to test in real screen readers, ideally by getting real users as they know how to use these tools. Consider contacting your local blind association and see if they offer testing services.
Screen Readers
Each platform has a screen reader, most are built in. Windows has the most variety.
For Windows
Use Narrator (it is built in, though not very good right now it is getting much better). Use it with Edge.
Download the free NVDA screen reader (but please donate to support it). Use it with Firefox
Download JAWS and use it in 40 minute increments for free. Use it with IE11.
For macOS
- Use VoiceOver (it is built in). Use it with Safari.
For iOS
- Use VoiceOver (it is built in). Use it with Safari.
For Android
- Use TalkBack. Use it with Firefox.
For Ubuntu
- Use Orca.
For ChromeOS
- Use ChromeVox (but only use ChromeVox in this scenario, not as a plug-in for Chrome on Windows or macOS).
Resources
These are handy to get started with testing on your own. Keyboard shortcuts are necessary to use a screen reader well, beyond just hitting the Tab key over and over and over.
