Class AVSpeechSynthesizer

  • All Implemented Interfaces:
    NSObject
    public class AVSpeechSynthesizer
extends NSObject
    AVSpeechSynthesizer AVSpeechSynthesizer allows speaking of speech utterances with a basic queuing mechanism. Create an instance of AVSpeechSynthesizer to start generating synthesized speech by using AVSpeechUtterance objects.

      • outputChannels

        public NSArray<? extends AVAudioSessionChannelDescription> outputChannels()
        Specify the audio channels to be used for synthesized speech as described by the channel descriptions in AVAudioSession's current route. Speech audio will be replicated to each specified channel. Default is nil, which implies system defaults.

      • pauseSpeakingAtBoundary

        public boolean pauseSpeakingAtBoundary​(long boundary)

      • setOutputChannels

        public void setOutputChannels​(NSArray<? extends AVAudioSessionChannelDescription> value)
        Specify the audio channels to be used for synthesized speech as described by the channel descriptions in AVAudioSession's current route. Speech audio will be replicated to each specified channel. Default is nil, which implies system defaults.

      • speakUtterance

        public void speakUtterance​(AVSpeechUtterance utterance)
        AVSpeechUtterances are queued by default. Enqueing the same AVSpeechUtterance that is already enqueued or is speaking will raise an exception.

      • stopSpeakingAtBoundary

        public boolean stopSpeakingAtBoundary​(long boundary)
        Call stopSpeakingAtBoundary: to interrupt current speech and clear the queue.

      • mixToTelephonyUplink

        public boolean mixToTelephonyUplink()
        Set to YES to send synthesized speech into an outgoing telephony audio stream. If there's no active call, setting this property has no effect.

      • setMixToTelephonyUplink

        public void setMixToTelephonyUplink​(boolean value)
        Set to YES to send synthesized speech into an outgoing telephony audio stream. If there's no active call, setting this property has no effect.

      • setUsesApplicationAudioSession

        public void setUsesApplicationAudioSession​(boolean value)
        The AVSpeechSynthesizer will use the AVAudioSession sharedInstance when set to YES. The AVSpeechSynthesizer will use a separate AVAudioSession for playback when set to NO. Additionally, the audio session will mix and duck other audio, and its active state will be managed automatically. The separate audio session will use AVAudioSessionRouteSharingPolicyDefault, which means that it may have a different route from the app’s shared instance session. Default is YES.

      • usesApplicationAudioSession

        public boolean usesApplicationAudioSession()
        The AVSpeechSynthesizer will use the AVAudioSession sharedInstance when set to YES. The AVSpeechSynthesizer will use a separate AVAudioSession for playback when set to NO. Additionally, the audio session will mix and duck other audio, and its active state will be managed automatically. The separate audio session will use AVAudioSessionRouteSharingPolicyDefault, which means that it may have a different route from the app’s shared instance session. Default is YES.

      • writeUtteranceToBufferCallback

        public void writeUtteranceToBufferCallback​(AVSpeechUtterance utterance,
                                           AVSpeechSynthesizer.Block_writeUtteranceToBufferCallback bufferCallback)
        Use this method to receive audio buffers that can be used to store or further process synthesized speech. The dictionary provided by -[AVSpeechSynthesisVoice audioFileSettings] can be used to create an AVAudioFile.
