Same here. Just updated to XCode 14.0.1 and testing on an IPHone 13 Pro Max IOS 16 I got the same error.
func saveAVSpeechUtteranceToFile() {
let utterance = AVSpeechUtterance(string: "This is an example of speech")
utterance.voice = AVSpeechSynthesisVoice(language: "en-US")
utterance.rate = 0.50
var output: AVAudioFile?
synthesizer.write(utterance) { (buffer: AVAudioBuffer) in
//At this point the debbugger throws> TTSPlaybackEnqueueFullAudioQueueBuffer: error -66686 enqueueing buffer several times (due to this callback is called several times)
guard let pcmBuffer = buffer as? AVAudioPCMBuffer else {
fatalError("unknown buffer type: \(buffer)")
}
if pcmBuffer.frameLength == 0 {
// Done
} else {
do{
// this closure is called multiple times. so to save a complete audio, try create a file only for once.
let fileURL = self.soundsDirectoryURL()!.appendingPathComponent("test.wav")
if output == nil {
try output = AVAudioFile(
forWriting: fileURL,
settings: pcmBuffer.format.settings,
commonFormat: .pcmFormatInt16,
interleaved: false)
}
try output?.write(from: pcmBuffer)
}catch {
print(error.localizedDescription)
}
}
}
}
