Question

How to fix Exception with an error code:0x15 (SPXERR_MIC_ERROR)

Meixuan MX4 Luo 0

I built a voice assistant, and after conversing for a while, the following error occurred in the voice recognition:
Error: ErrorCode=RuntimeError, ErrorDetails=0x15 (SPXERR_MIC_ERROR)
My calling method is as follows. Could you please tell me why this problem occurred and how to solve it?

private fun recognizeFromMicrophone(speechConfig: SpeechConfig?) {
    try {
        val audioConfig = AudioConfig.fromDefaultMicrophoneInput()
        speechRecognizer = SpeechRecognizer(speechConfig, audioConfig)

        myRecognizerListener?.onBeginOfSpeech()
        recognizingResult = ""

      
        speechRecognizer.recognizing.addEventListener { _, e ->
            handleRecognizingEvent(e.result.text)
        }

      
        CoroutineScope(Dispatchers.IO).launch {
            try {
                val speechRecognitionResult: SpeechRecognitionResult = speechRecognizer.recognizeOnceAsync().get()
                handleRecognitionResult(speechRecognitionResult)
            } catch (e: Exception) {
                VoiceLog.error(TAG, "Error: " + e.message)
                withContext(Dispatchers.Main) {
                    myRecognizerListener?.onError(VoiceError("Azure_Recognize_Error_400", e.message ?: "Unknown error"))
                }
            }
        }
    } catch (e: Exception) {
        VoiceLog.error(TAG, "Error starting speech recognizer: ${e.message}")
    }
}

Thanks for getting back. The cause of SPXERR_MIC_ERROR can be due to below:

i. Microphone not connected;

ii. Microphone disabled or muted;

iii. Mic was access by another Application;

iv. Incorrect audio configuration;

v. Insufficient permission

....

SPXERR_MIC_ERROR is a microphone initialization error so there is something wrong with your setup. Please ensure that you have checked the above mentioned points.

.

Please refer the sample code of android (interoperable with kotlin) for mic scenario here to repro/debug:

https://github.com/Azure-Samples/cognitive-services-speech-sdk/tree/e392c9ca09d44ebd65081e7cb44593a2b16cd5a7/quickstart/java/android/from-microphone

Currently, I am using voice recognition on the Android system. I have confirmed that the configuration for voice recognition is correct, as it starts properly. However, after a period of conversation, the voice recognition will produce an error : SPXERR_MIC_ERROR, and once the error occurs, it cannot be used again and will continuously report the error. The only way to restore normal functionality is to restart the application.

I captured the error log, and the error starts at line 10448. logFile.txt The voice recognition prior to that was functioning normally.

@Meixuan MX4 Luo Thanks for sharing the details, Please follow the below action plan and share the updates:

.

Plan 1:

On Windows, make sure that your application has permission to access the microphone. You can check this by going to Settings -> Privacy -> Microphone and ensuring that "Allow apps to access your microphone" is enabled and that Python (or your IDE) is listed and enabled in the app list.

.

.

Plan 2:

Default Microphone Configuration:

Ensure that the default microphone is set correctly. You can set this in Control Panel -> Hardware and Sound -> Sound -> Recording tab. Right-click on your microphone and select "Set as Default Device".

.

.

Plan 3:

Update Drivers:

Ensure that your microphone drivers are up to date. You can update them through the Device Manager.

.

.

Plan 4:

Code Adjustments:

Specify the audio input device explicitly in your code. You can list available audio devices and select the appropriate one. Below is an example in Python, change it accordingly for your code:

def get_microphone(): # List available audio input devices audio_config = speechsdk.audio.AudioConfig(use_default_microphone=True) return audio_config . . # Get the audio input from the default microphone audio_config = get_microphone() speech_recognizer = speechsdk.SpeechRecognizer(speech_config=speech_config, audio_config=audio_config)

.

.

@Meixuan MX4 Luo I tried Android example but didn't repro in 4 hour audio.

https://github.com/Azure-Samples/cognitive-services-speech-sdk/tree/master/samples/java/android/sdkdemo/app/src/main/java/com/microsoft/cognitiveservices/speech/samples/sdkdemo

Could you please refer the sample code. (for example, start, stop and close recognizer...) ? Awaiting your reply.
