Is there any free CMS for screen reader compatibility for admin?

Is there any free CMS to operate a small business website/blog with screen reader compatibility where a blind person can update the content and other thing开发者_如何学运维s via CMS administration using screen reader software and keyboard?

I used Drupal several years ago with jaws for windows as both an administrator and content author with good results. For an IBM article on Drupal accessibility see this For info on accessibility from the Drupal site see this

Check out Plone.

It's been developed to meet and exceed the WCAG-AA accessibility standard. It will work with Jaws or your choice of screen readers.

I work with the World Institute on Disability whose website is developed in Plone.
