ios speech recognition Error Domain=kAFAssistantErrorDomain Code=216 “(null)”

Question

Basically I am learning ios speech recognition module following this tutorial: https://medium.com/ios-os-x-development/speech-recognition-with-swift-in-ios-10-50d5f4e59c48

Answer 1

This will prevent two errors: The above mentioned Code=216 and the 'SFSpeechAudioBufferRecognitionRequest cannot be re-used' error.

1. Stop recognition with finish not with cancel

2. Stop audio

like so:

    // stop recognition
    recognitionTask?.finish()
    recognitionTask = nil

    // stop audio
    request.endAudio()
    audioEngine.stop()
    audioEngine.inputNode.removeTap(onBus: 0) // Remove tap on bus when stopping recording.

P.S. audioEngine.inputNode seems to be no longer an optional value, therefore I used no if let construct.
