I wrote this code to test the 158 available voices on XCODE15 and iOS17, so far the 10 I tested are crashing the app. Fred en-US is working. Can we get more hands to test the whole list and provide the working voices? https://gist.github.com/Koze/d1de49c24fc28375a9e314c72f7fdae4 Thanks. import SwiftUI import AVFoundation // Define a struct to hold voice information struct VoiceInfo: Comparable { var name: String var language: String var identifier: String static func < (lhs: VoiceInfo, rhs: VoiceInfo) -> Bool { if lhs.language == rhs.language { return lhs.name < rhs.name } return lhs.language < rhs.language } } struct ContentView: View { @State private var selectedVoice = 0 @State private var textToSpeak = "Hello, World!" let synthesizer = AVSpeechSynthesizer() // Create and sort the array of voice information let voices: [VoiceInfo] = [ VoiceInfo(name: "Majed", language: "ar-001", identifier: "com.apple.voice.compact.ar-001.Maged"), ... ].sorted() var body: some View { VStack { Picker("Select a Voice", selection: $selectedVoice) { ForEach(0 ..< voices.count, id: \.self) { index in Text("\(voices[index].name) (\(voices[index].language))") .tag(index) } } .pickerStyle(WheelPickerStyle()) .padding() TextField("Enter text to speak", text: $textToSpeak) .textFieldStyle(RoundedBorderTextFieldStyle()) .padding() Button("Speak") { speakText() } .padding() } } func speakText() { let utterance = AVSpeechUtterance(string: textToSpeak) utterance.voice = AVSpeechSynthesisVoice(identifier: voices[selectedVoice].identifier) synthesizer.speak(utterance) } } struct ContentView_Previews: PreviewProvider { static var previews: some View { ContentView() } } #Preview { ContentView() }

Hello All, I am having very similar errors like the first original post since I updated to XCODE 15 and simulating on iOS 17.x.x. I did NOT have issues related to Text to Speech while I was working on XCODE 14.3.1 and simulating on iOS 16.4 before the update in development and in production. Here are the errors I am getting from XCODE 15 simulating on iOS 17.x.x. The simulator freezes and I receive below errors: Query for com.apple.MobileAsset.VoiceServices.GryphonVoice failed: 2 Unable to list voice folder Unable to list voice folder Query for com.apple.MobileAsset.VoiceServices.GryphonVoice failed: 2 Unable to list voice folder Query for com.apple.MobileAsset.VoiceServicesVocalizerVoice failed: 2 Unable to list voice folder Query for com.apple.MobileAsset.VoiceServices.GryphonVoice failed: 2 Unable to list voice folder 1 log/signpost messages lost due to high rates in live mode recording.

The app works fine but I receive these messages: … [AXTTSCommon] MauiVocalizer: 11006 (Can't compile rule): regularExpression=Ne-\Yo, message=unrecognized character follows , characterPosition=4 … [AXTTSCommon] MauiVocalizer: 16038 (Resource load failed): component=ttt/re, uri=rlst/yosemite/set/mnc, contentType=application/x-vocalizer-rettt+text;loader=broker, lhError=88602000 … [catalog] Query for com.apple.MobileAsset.VoiceServices.VoiceResources failed: 2 … [catalog] Query for com.apple.MobileAsset.VoiceServices.VoiceResources failed: 2 … changing items while animating can result in a corrupted navigation bar … … [AXTTSCommon] MauiVocalizer: 11006 (Can't compile rule): regularExpression=Ne-\Yo, message=unrecognized character follows , characterPosition=4 … [AXTTSCommon] MauiVocalizer: 16038 (Resource load failed): component=ttt/re, uri=rlst/yosemite/set/mnc, contentType=application/x-vocalizer-rettt+text;loader=broker, lhError=88602000 … … [AXTTSCommon] MauiVocalizer: 11006 (Can't compile rule): regularExpression=Ne-\Yo, message=unrecognized character follows , characterPosition=4 … [AXTTSCommon] MauiVocalizer: 16038 (Resource load failed): component=ttt/re, uri=rlst/yosemite/set/mnc, contentType=application/x-vocalizer-rettt+text;loader=broker, lhError=88602000 … [catalog] Query for com.apple.MobileAsset.VoiceServices.VoiceResources failed: 2 … … [AXTTSCommon] MauiVocalizer: 11006 (Can't compile rule): regularExpression=Ne-\Yo, message=unrecognized character follows , characterPosition=4 … [AXTTSCommon] MauiVocalizer: 16038 (Resource load failed): component=ttt/re, uri=rlst/yosemite/set/mnc, contentType=application/x-vocalizer-rettt+text;loader=broker, lhError=88602000 Now the app store production version freezes in any device running 17.x.x and not usable anymore. I opened a case with Apple development team but I have not received a reply yet. The zh-CN.Tingting, and en-US.Samantha keep repeating over 350,000 times each in the errors. It also seems that I am receiving: … [catalog] Query for com.apple.MobileAsset.VoiceServices.VoiceResources failed: 2 Without affecting the app in XCODE 14.x. And a similar error: Query for com.apple.MobileAsset.VoiceServicesVocalizerVoice failed: 2 Unable to list voice folder Query for com.apple.MobileAsset.VoiceServices.GryphonVoice failed: 2 Unable to list voice folder In XCODE 15. Any help will be highly appreciated to find a quick work around or a fix. Thanks
