# isVoiceOnly

A Boolean value that indicates whether the system performs the app intent in a voice-only context.

```
var isVoiceOnly: Bool { get }
```

## Discussion

If [`isVoiceOnly`](/documentation/AppIntents/IntentSystemContext/isVoiceOnly) is `true`, adjust the intent’s result to include a more speakable summary,
and make sure a person can understand responses and dialog without visuals such as tables, graphics, or other user-interface elements.

Generally, return an [`IntentDialog`](/documentation/AppIntents/IntentDialog) from your intent. The system can
choose the best information from the dialog to present for a person’s context.
Consult [`isVoiceOnly`](/documentation/AppIntents/IntentSystemContext/isVoiceOnly) when your app intent returns dynamic, free-form output, such as
generated recommendations, summarized search results, or natural-language responses
you generate on the fly.
