Voice on AVSpeechSynthesizer won't change"

Issue with AVSpeechSynthesizer

I’m using AVSpeechSynthesizer to pass text to be spoken. When I change the voice to male in the settings, the text is still being spoken in a female voice.

func speakOutText(_ textToRead:String ){
    let audioSession = AVAudioSession.sharedInstance()
    do {
        try audioSession.setCategory(AVAudioSessionCategoryPlayback)
        try audioSession.setMode(AVAudioSessionModeDefault)
        try audioSession.setActive(true, with: .notifyOthersOnDeactivation)
    } catch {
        print("audioSession properties weren't set because of an error.")
    }
    let speakUtterance = AVSpeechUtterance.init(string: textToRead);
    speakUtterance.voice  = AVSpeechSynthesisVoice(language: "en-IN")
    speakUtterance.pitchMultiplier = 1.2
    speakUtterance.rate   = 0.5
    speechSynthesizer.speak(speakUtterance)

}

Why is the text still being spoken in a female voice even after changing to a male voice in the settings?

The AVSpeechSynthesisVoice language code for male voice in English is “en-US” instead of “en-IN”. Change the following line:

speakUtterance.voice  = AVSpeechSynthesisVoice(language: "en-IN")

to

speakUtterance.voice  = AVSpeechSynthesisVoice(language: "en-US")
