Почему SpeechSynthesizer не работает при использовании SpeechRecouncer? ⇐ IOS

[Anonymous]

This is clearly a duplicate of several other posts, but all of them are several years old, and none of their solutions work for me.

I am using SpeechSynthesizer and SpeechRecognizer. After a recognition task completes, the SpeechSynthesizer stops producing audible output.

I am using the latest SwiftUI in Xcode 15.2, deploying to an iPhone 14 Pro running iOS 17.3.1.

A couple of the relevant posts are:

AVSpeechSynthesizer does not speak after using SFSpeechRecognizer

iOS: AVSpeechSynthesizer doesn't work after recording with SFSpeechRecognizer

Here's my SpeechSynthesizer function:

func speak(_ text: String) { let utterance = AVSpeechUtterance(string: text) utterance.voice = AVSpeechSynthesisVoice(identifier: self.appState.chatParameters.voiceIdentifer) utterance.rate = 0.5 speechSynthesizer.speak(utterance) } And here's the code for setting up the SpeechRecognizer (borrowed from https://www.linkedin.com/pulse/transcri ... ad-chattha):

private static func prepareEngine() throws -> (AVAudioEngine, SFSpeechAudioBufferRecognitionRequest) { print("prepareEngine()") let audioEngine = AVAudioEngine() let request = SFSpeechAudioBufferRecognitionRequest() request.shouldReportPartialResults = false request.requiresOnDeviceRecognition = true let audioSession = AVAudioSession.sharedInstance() try audioSession.setCategory(.playAndRecord) try audioSession.setActive(true, options: .notifyOthersOnDeactivation) let inputNode = audioEngine.inputNode let recordingFormat = inputNode.outputFormat(forBus: 0) inputNode.installTap(onBus: 0, bufferSize: 1024, format: recordingFormat) { (buffer: AVAudioPCMBuffer, when: AVAudioTime) in request.append(buffer) } audioEngine.prepare() try audioEngine.start() return (audioEngine, request) } SpeechSynthesizer works fine as long as I don't call prepareEngine().

Thanks in advance for any assistance.
