In a .NET project, you can't create a Windows.Media.SpeechRecognition object in administrator mode

Hi @jj t , Welcome to Microsoft Q&A,

Is there any reproducible code? Do you have a reference to the corresponding package? You can check this document: https://learn.microsoft.com/en-us/windows/apps/design/input/speech-recognition .

You can also try this github code.

    private async Task<bool> InitializeRecognizer()

    {

        var commonds = GetCommands();

        if (commonds == null) { return false; }

        bool initResul = true;

        if (speechRecognizer != null)

        {

            speechRecognizer.StateChanged -= SpeechRecognizerStateChanged;

            speechRecognizer.ContinuousRecognitionSession.Completed -= ContinuousRecognitionSessionCompleted;

Try to use this:

private async Task<bool> InitializeRecognizerAsync()
{
    var commands = GetCommands();
    if (commands == null) { return false; }

    bool initResult = true;

    if (speechRecognizer != null)
    {
        speechRecognizer.StateChanged -= SpeechRecognizerStateChanged;
        speechRecognizer.ContinuousRecognitionSession.Completed -= ContinuousRecognitionSessionCompleted;
        speechRecognizer.ContinuousRecognitionSession.ResultGenerated -= ContinuousRecognitionSessionResultGenerated;
        
        speechRecognizer.Dispose();
        speechRecognizer = null;
    }

    try
    {
        speechRecognizer = new SpeechRecognizer();
        speechRecognizer.StateChanged += SpeechRecognizerStateChanged;
        
        speechRecognizer.Constraints.Add(new SpeechRecognitionListConstraint(commands, CurrentLanguage.ToString()));
        SpeechRecognitionCompilationResult result = await speechRecognizer.CompileConstraintsAsync();

        if (result.Status == SpeechRecognitionResultStatus.Success)
        {
            speechRecognizer.ContinuousRecognitionSession.Completed += ContinuousRecognitionSessionCompleted;
            speechRecognizer.ContinuousRecognitionSession.ResultGenerated += ContinuousRecognitionSessionResultGenerated;
        }
        else
        {
            initResult = false;
        }
    }
    catch (Exception ex)
    {
        if ((uint)ex.HResult == 0x8004503a)
        {
            // Handle specific exception or add logging if needed
        }
        
        initResult = false;
    }

    return initResult;
}
