# pauseSpeaking(at:)

Pauses speech at the boundary you specify.

```
func pauseSpeaking(at boundary: AVSpeechBoundary) -> Bool
```

## Parameters

`boundary`

An enumeration that describes whether to pause speech immediately or only after the synthesizer finishes speaking the current word.

## Return Value

<doc://com.apple.documentation/documentation/Swift/true> if speech pauses; otherwise, <doc://com.apple.documentation/documentation/Swift/false>.

## Discussion

The `boundary` parameter also affects how the speech synthesizer resumes speaking text after a pause and call to [`continueSpeaking()`](/documentation/AVFAudio/AVSpeechSynthesizer/continueSpeaking()). If the boundary is [`AVSpeechBoundary.immediate`](/documentation/AVFAudio/AVSpeechBoundary/immediate), speech resumes from the exact point where it pauses, even if that point occurs in the middle of speaking a word. If the boundary is [`AVSpeechBoundary.word`](/documentation/AVFAudio/AVSpeechBoundary/word), speech resumes from the word that follows the last spoken word where it pauses.
