# AttributeScopes.AccessibilityAttributes.AnnouncementPriorityAttribute

An attribute to define the urgency of the announcement.

```
@frozen enum AnnouncementPriorityAttribute
```

## Overview

For example, when `low` is specified, announcements are queued
and spoken when other speech utterances have completed. When
`default` is specified, announcements will interrupt existing speech,
but are interruptible if a new speech utterance is started. When `high`
is specified, announcements will interrupt other speech and cannot be
interrupted once started.

## Topics
