# AttributeScopes.AccessibilityAttributes.SpeechSSMLAttribute

An attribute for an SSML fragment describing how the annotated range should be spoken.

## Declaration

```swift
@frozen enum SpeechSSMLAttribute
```

## Overview

Overview The value is an SSML fragment string. Assistive technologies that produce speech use the fragment to determine pronunciation, language, pacing, and emphasis for the annotated range. Non-speech clients (e.g. Braille) ignore this attribute. When present, this attribute takes precedence over the older single-purpose speech attributes (IPA notation, spell out, pitch, punctuation, language).
