Instance Method

speechSynthesizer(_:didCancel:)

Tells the delegate when the synthesizer has canceled speaking an utterance.

Declaration

optional func speechSynthesizer(_ synthesizer: AVSpeechSynthesizer, didCancel utterance: AVSpeechUtterance)

Parameters

synthesizer

The synthesizer speaking the utterance that this message applies to.

utterance

The utterance during which speech was canceled.

Discussion

This message is sent only if speech is stopped (using the stopSpeaking(at:) method) while an utterance is being spoken. It is not sent if the synthesizer is currently in a delay between utterances when speech stops. This message is sent only for the utterance currently being spoken, not for utterances yet to be handled.
