Based on this WWDC2018 video, we can dynamically change how words are pronounced in AVSpeechSynthesizer.

I'm trying to do that in my Xamarin App, but I can't find the accessibilitySpeechIPANotationconstant.

In the doc of NSMutableAttributedString.AddAttribute(...) it says that the constants can be found here: UIKit.UIStringAttributeKey. Yet the one I'm looking for isn't there.

Does anyone know what the actual string value of the constant is? Or even better, where I can find in in Xamarin.iOS?

(My app uses xamarin.ios v4.0.30319, if the constant is in a newer version of the framework, I'll update it, but google doesn't seem to give me any result when I search for it.)
