# accessibilitySpeechQueueAnnouncement

A key that indicates whether to queue an announcement behind existing speech or to interrupt it.

```
nonisolated static let accessibilitySpeechQueueAnnouncement: NSAttributedString.Key
```

## Discussion

The value of this key is an [`NSNumber`](/documentation/Foundation/NSNumber) object that the system interprets as a Boolean value. When the value is <doc://com.apple.documentation/documentation/Swift/true>, the system queues the announcement behind existing speech. When the value is <doc://com.apple.documentation/documentation/Swift/false>, the announcement interrupts the existing speech. The default behavior is to interrupt existing speech.
