audio recognition stream listen only once.

[taimoor522]

Why does the stream only run once.....???

recognitionStream.listen((event) {
    print(listening');
    },
);

To help me with your problem, please provide more information, such as logs and a sample of your code. If you cant provide your code, at least provide what parameters you have used in the stream.

@Caldarie

recognitionStream = TfliteAudio.startAudioRecognition(
            sampleRate: 44100,
            bufferSize: 22016,
          );
audioSubscriber = recognitionStream.listen(
            (event) async {
              try {
                if (clapServiceStatus == true &&
                    event['recognitionResult'] == 'clap') {
                  // stop service when clap detected
                  UtilityFunctions.showPhoneFoundAlertDialog(
                      context, () => stopStartClapService(context));
                  // if vibration is set to on then vibrate phone
                  bool clapVib = prefs.getBool('clapVibration') ?? false;
                  if (await (Vibration.hasVibrator()) == true && clapVib) {
                    Vibration.vibrate(duration: 1000, amplitude: 255);
                  }

                  // if flashlight is set to on then turn flashlight
                  bool clapFlash = prefs.getBool('clapFlashLight') ?? false;
                  if (clapFlash) turnOnFlashLight();

                  // play melody if enabled by user
                  if (clapMelody == true) playMelody(volume);
                }
                if (prefs.getBool('whistleService') == true &&
                    event['recognitionResult'] == 'whistle') {
                  UtilityFunctions.showPhoneFoundAlertDialog(
                      context, () => stopStartWhistleService(context));

                  // if vibration is set to on then vibrate phone
                  bool whistleVib = prefs.getBool('whistleVibration') ?? false;
                  if (await (Vibration.hasVibrator()) == true && whistleVib) {
                    Vibration.vibrate(duration: 1000, amplitude: 255);
                  }

                  // if flashlight is set to on then turn flashlight
                  bool whistleFlash =
                      prefs.getBool('whistleFlashLight') ?? false;
                  if (whistleFlash) turnOnFlashLight();

                  // play melody if enabled by user
                  if (whistleMelody == true) playMelody(volume);
                }
              } catch (_) {}
            },
            cancelOnError: true,
            onError: (_) {
              audioSubscriber.cancel();
            },
            onDone: () {
              audioSubscriber.cancel();
            });

recognitionStream listen-only run once. Why? If it is a stream then it should keep listening to the audio. I wrapped it inside a periodic timer to run it again and again.

Can you provide the logs as well please.

[taimoor522]

There is no need of logs.
The problem is simply that when I run the code below, it only prints the msg once even if it is a stream.

recognitionStream = TfliteAudio.startAudioRecognition(
            sampleRate: 44100,
            bufferSize: 22016,
          );
recognitionStream.listen((event) {
    print('msg');
    },
);

With all due respect, logs give me a clearer picture as to whether the problem lies with the plugin or code. Help me help you, yes?

Also, you may need to read up more on how streams work.
