You can play standard Windows sound files or linguistically enhanced sound files by choosing the Play command from the Audio menu or the editor's toolbar. The Pause and Stop commands enable you to pause or stop playing the sound file. As you play the file, the sample mouth image animates to show how the lip-sync information could be used by a Microsoft Agent character.
You can also play a selected portion of a sound file by dragging a selection in the Audio Representation or clicking a word or phoneme label, then choosing Play. You can extend an existing selection by pressing shift and clicking or pressing shift and dragging to the new location in the Audio Representation.
