Play AVSpeechUtterance in local notification (swift3)

My codes launches a local notification. I can figure out how to add a title to the notification but I can not figure out how to use a custom sound. Specifically I want to use avseechutterance to speak the variable a in my code.

     let content = UNMutableNotificationContent()

      //a goes on the line below
    content.sound =



    let a = AVSpeechUtterance(string: " Good afternoon ")

    let synthesizer = AVSpeechSynthesizer()




    synthesizer.speak(a)

    a.voice = AVSpeechSynthesisVoice(language: "en-US")
    a.rate = 0.08

Hi @zalubski

I don’t think it’s possible. Custom notification sound should be an instance of the UNNotificationSound class, AVSpeechSynthesisVoice can’t help you with this.
It should look something like this:

content.sound = UNNotificationSound(named: soundName)

@zalubski , @nikita_gaydukov Hello, I am stuck on the same topic

// playing sound in notifications
let notificationContent = UNMutableNotificationContent()

notificationContent.sound = UNNotificationSound(named: UNNotificationSoundName(rawValue: ringtoneName + “.mp3”))

how do I use the text to speech inside the notificationContent.sound = UNNotificationSound(named: )

following is my code for the text to speech conversion

// Text to speech
try AVAudioSession.sharedInstance().setCategory(AVAudioSession.Category.playback)
try audioSession.setActive(true)

        UIApplication.shared.beginReceivingRemoteControlEvents()
        
        let utterance = AVSpeechUtterance(string: message) // message is the notificaiton title i am passing through the string
        utterance.rate = 0.5
        utterance.volume = 0.8
        utterance.voice = AVSpeechSynthesisVoice(language: languageCode)
        
        synthesizer.speak(utterance)
        currentCount += 1
