speechSynthesizer delayed by UILongPressGestureRecognizer

I'd have a speech at a begin of a long pressure:

Code Block class Cell: UITableViewCell
{
	override func awakeFromNib()
	{
		...
		let willSpeech = UILongPressGestureRecognizer(target: self, action: #selector(longPress(gesture:)))
		button.addGestureRecognizer(willSpeech)
	}
	@objc func longPress(gesture: UILongPressGestureRecognizer)
	{
		switch gesture.state
		{
		case .began:
			let utterance = AVSpeechUtterance(string: "hello")
			let speechSynthesizer = AVSpeechSynthesizer()
			speechSynthesizer.speak(utterance)
		...
		}
	}
}

Code Block
class Cell: UITableViewCell
{
override func awakeFromNib()
{
...
let willSpeech = UILongPressGestureRecognizer(target: self, action: #selector(longPress(gesture:)))
button.addGestureRecognizer(willSpeech)
}
@objc func longPress(gesture: UILongPressGestureRecognizer)
{
switch gesture.state
{
case .began:
let utterance = AVSpeechUtterance(string: "hello")
let speechSynthesizer = AVSpeechSynthesizer()
speechSynthesizer.speak(utterance)
...
}
}
}

But the speech start only when the button is released.
Is there a way to let the speech start immediately even during a long pressure gesture recogniser?
