Using two instances of AVSpeechSynthesizer simultaneously

I would like to use two instances of AVSpeechSynthesizer simultaneously.

let firstSynthesizer = AVSpeechSynthesizer()
let secondSynthesizer = AVSpeechSynthesizer()

func foo() {
   let utterance = AVSpeechUtterance(string: "Foo Foo Foo Foo Foo")
   utterance.rate = 0.4
   utterance.voice = AVSpeechSynthesisVoice(language: "en-US")
   firstSynthesizer.speak(utterance)
}

func bar() {
   let utterance = AVSpeechUtterance(string: "Bar Bar Bar Bar Bar")
   utterance.rate = 0.4
   utterance.voice = AVSpeechSynthesisVoice(language: "en-US")
   secondSynthesizer.speak(utterance)
}

When I call foo() and bar(), the texts are not read at the same time but one after the other.

It's definitely not possible in iOS 12, only one speech synthesis is vocally processed at a time.

However, an audio session can be played together with the speech synthesis.
