SA Publisher for web generation : System Architect Publisher : Using screen readers with diagrams
  
Using screen readers with diagrams
System Architect Publisher provides access for the hearing impaired by working with screen reader applications, such as JAWS from Freedom Scientific. A screen reader application reads a symbol’s tooltip content (usually its name and type), and then converts it to sound.
To use this feature
1 Install a Java Access Bridge.
2 Open your screen reader application.
3 Open the website you created with System Architect Publisher and navigate to a diagram.
4 Move the pointer over a symbol to hear its tooltip content.
