# speechSynthesizer(_:didFinish:)

Tells the delegate when the synthesizer finishes speaking an utterance.

## Declaration

```swift
optional func speechSynthesizer(_ synthesizer: AVSpeechSynthesizer, didFinish utterance: AVSpeechUtterance)
```

## Parameters

- `synthesizer`: The speech synthesizer that finishes speaking the utterance.
- `utterance`: The utterance that the speech synthesizer finishes speaking.

## Discussion

Discussion The system ignores the final utterance’s postUtteranceDelay and calls this method immediately when speech ends.
