MicrophoneRecognitionClient stops working after onError callback #4

Closed phongcao closed 7 years ago

Repro Steps:

  1. Press start button.
  2. Quickly switch the airplane mode on and off in order to simulate the network connection drops.
  3. onError callback returns: "Transport error Unknown error: -2147418113".
  4. Press start button again.
  5. The app stops working with error: "_SpeechClientStatusMicrophoneInUse".

When this issue happens, it doesn't help even if I try to stop the recognition using endMicAndRecognition method or re-initialize the MicrophoneRecognitionClient. The only way is to reset the app.

This has been happening to me too. Though in my case, it was while running the app with a simulated poor connection.

On an iPhone:

  1. Settings > Developer > Network Link Conditioner Status > Enable > Very Bad Network.
  2. Launch SpeechRecognitionServerExample.
  3. Press start button.
  4. onError callback returns: "Transport error Unknown error: -2147418113".
  5. Press start button again.
  6. The app stops working with error: "_SpeechClientStatusMicrophoneInUse".

After getting the _SpeechClientStatusMicrophoneInUse status, any subsequent calls to endMicAndRecognition never return (the app just hangs).

Can you verify if the latest SDK has addressed the issue?

It seems to work great now. Thanks!
