open class RSDSpeechSynthesizer : NSObject, RSDVoiceBox, AVSpeechSynthesizerDelegate

RSDSpeechSynthesizer is a concrete implementation of the RSDVoiceBox protocol that uses the AVSpeechSynthesizer to synthesize text to sound.

  • A singleton instance of the voice box.

    Declaration

    Swift

    public static var shared: RSDVoiceBox

  • Is the voice box currently speaking? The default implementation will return true if the AVSpeechSynthesizer is speaking.

    open func stopTalking()

AVSpeechSynthesizerDelegate

  • Called when the text is synthesizer is finished.

    Declaration

    Swift

    open func speechSynthesizer(_ synthesizer: AVSpeechSynthesizer, didFinish utterance: AVSpeechUtterance)

  • Called when the text is synthesizer is cancelled.

    Declaration
