# stopSpeaking(at:)

Stops speech at the boundary you specify.

## Declaration

```swift
func stopSpeaking(at boundary: AVSpeechBoundary) -> Bool
```

## Parameters

- `boundary`: An enumeration that describes whether to stop speech immediately or only after the synthesizer finishes speaking the current word.

## Return Value

Return Value true if speech stops; otherwise, false.

## Discussion

Discussion Unlike pausing a speech synthesizer, which can resume after a pause, stopping the synthesizer immediately cancels speech and removes all unspoken utterances from the synthesizer’s queue.
