Question

I'm using AVSpeechSynthesizer for voice out some text data, it'll work for first time but it didn't work after that.

I'm getting below messages.

Error:-

Below i share my code.

 let synth = AVSpeechSynthesizer()

 fileprivate func speakText(voiceOutdata: String )
 {
    let utterance = AVSpeechUtterance(string: voiceOutdata)
    utterance.voice = AVSpeechSynthesisVoice(language: "en-US")
    synth.speak(utterance)
 }

You need to set the AVAudioSession for performing such tasks. Here is my working code. Hope this helps.

func speakText(voiceOutdata: String ) {
    do {
        try AVAudioSession.sharedInstance().setCategory(AVAudioSession.Category.playAndRecord, mode: .default, options: .defaultToSpeaker)
        try AVAudioSession.sharedInstance().setActive(true, options: .notifyOthersOnDeactivation)
    } catch {
        print("audioSession properties weren't set because of an error.")
    }

    let utterance = AVSpeechUtterance(string: voiceOutdata)
    utterance.voice = AVSpeechSynthesisVoice(language: "en-US")

    let synth = AVSpeechSynthesizer()
    synth.speak(utterance)

    defer {
        disableAVSession()
    }
}

private func disableAVSession() {
    do {
        try AVAudioSession.sharedInstance().setActive(false, options: .notifyOthersOnDeactivation)
    } catch {
        print("audioSession properties weren't disable.")
    }
}

try below code:

let synthesizer = AVSpeechSynthesizer()
 fileprivate func speakText(voiceOutdata: String ){
    synthesizer.stopSpeakingAtBoundary(.Immediate)
    let utterance = AVSpeechUtterance(string: voiceOutdata)
    utterance.voice = AVSpeechSynthesisVoice(language: "en-US")
    synthesizer.speakUtterance(utterance)
}

    try AVAudioSession.sharedInstance().setActive(true, options: .notifyOthersOnDeactivation)
} catch {
