Use this property to specify short custom phrases that are unique to your app. You might include phrases with the names of characters, products, or places that are specific to your app. You might also include domain-specific terminology or unusual or made-up words. Assigning custom phrases to this property improves the likelihood of those phrases being recognized.
Keep phrases relatively brief, limiting them to one or two words whenever possible. Lengthy phrases are less likely to be recognized. In addition, try to limit each phrase to something the user can say without pausing.
