Possible Values

overdub The user prefers to substitute one voice track for another.
subtitle The user prefers to display text in a language different from the one currently being used in the audio track.

Remarks

Evaluates to true if the user preference matches this attribute value. Evaluates to false if they do not match.
If the systemOverdubOrSubtitle attribute is used on an HTML element within a switch statement, it is not necessary to apply the time2 behavior to the HTML element.
To turn captions on or off, select the Use ShowSounds check box under the Sound tab of Accessibility Options located in Control Panel.

Example

This example demonstrates how to use the systemOverdubOrSubtitle attribute. If captioning (Use ShowSounds) is not set to on, the first t:AUDIO evaluates true and starts to play. Otherwise, the second t:AUDIO evaluates true and starts to play.
