Use VoiceOver activities
Use VoiceOver activities to create groups of preferences for specific uses. For example, create an activity to use a certain voice and faster speaking rate when you shop online, then create a second activity to use a different voice and slower speaking rate when you read online articles.
Note: VO represents the VoiceOver modifier.
