I am still experiencing this in iOS 18.1 using Xcode 16.

See the following sample project:
import SwiftUI
import AVFoundation
class Synthesizer: NSObject, AVSpeechSynthesizerDelegate {
let avSpeechSynthesizer = AVSpeechSynthesizer()
override init() {
super.init()
avSpeechSynthesizer.delegate = self
}
func play() {
let utterance = AVSpeechUtterance(string: "Hello world, this is a long string of many words many words many words many words many words")
avSpeechSynthesizer.speak(utterance)
}
func speechSynthesizer(_ synthesizer: AVSpeechSynthesizer, didStart utterance: AVSpeechUtterance) {
print("didStart \(utterance)")
DispatchQueue.main.asyncAfter(deadline: .now() + 2) { [weak self] in
self?.avSpeechSynthesizer.stopSpeaking(at: .word)
}
}
func speechSynthesizer(_ synthesizer: AVSpeechSynthesizer, didFinish utterance: AVSpeechUtterance) {
print("didFinish \(utterance)")
}
func speechSynthesizer(_ synthesizer: AVSpeechSynthesizer, didCancel utterance: AVSpeechUtterance) {
print("didCancel \(utterance)")
}
}
struct ContentView: View {
@State private var synthesizer = Synthesizer()
var body: some View {
Button("Play") {
synthesizer.play()
}
}
}
