Using captioning
For users who are hearing impaired, you can add text captioning to your movies. Captioning is
the practice of displaying text that corresponds to spoken narration or other sounds being played.
Using the captioning behaviors in addition to the text-to-speech behaviors lets you make your
movies accessible to users with all types of disabilities.
There are two captioning behaviors that are designed to be used together. Each is designed to be
used with the keyboard navigation and text-to-speech behaviors. For information about applying
text-to-speech behaviors, see “Enabling text-to-speech” on page 555.To enable captioning, you
attach the Accessibility Captioning behavior to an empty text sprite that will display the captions.
Next, you attach the Accessibility Sync Caption behavior to a sprite that has already had speech
enabled with the text-to-speech behaviors.
To apply the Accessibility Captioning behavior:
1
Place the text sprite that you want to display caption text on the Stage.
2
Drag the Accessibility Captioning behavior from the Library palette to the text sprite.
3
In the dialog box that appears, select the behavior group name for the scene. This step
associates the accessibility behaviors in the scene with one another so they work properly.
4
Click OK.
Next, you attach the Accessibility Sync Caption behavior to a sprite that has already had
speech enabled.
