How to add continuous speech/talk - .NET MAUI Speech

I have the below .Net MAUI code that works great.

I want to add continuous speech, I mean when I speak, the recorder must not stop until I press stop button.

In the below code, when I stop speaking, or I pause for like 2-3 sec, it stops itself, so I don't want it to behave like that.

I want it to continue recording even if i pause my speech for 2-3 sec.

public class SpeechToTextImplementation : ISpeechToText

{

public event EventHandler<SpeechToTextRecognitionResultUpdatedEventArgs> RecognitionResultUpdated = null!;

public event EventHandler<SpeechToTextRecognitionResultCompletedEventArgs> RecognitionResultCompleted = null!;

public event EventHandler<SpeechToTextStateChangedEventArgs> StateChanged = null!;

public SpeechToTextState CurrentState { get; private set; } = SpeechToTextState.Idle;

public async Task<SpeechToTextResult> ListenAsync(CultureInfo culture, IProgress<string>? recognitionResult, CancellationToken cancellationToken)

{

await Task.Delay(2000, cancellationToken);

string finalText = "Recognized text from ListenAsync.";

recognitionResult?.Report(finalText);

return new SpeechToTextResult(finalText, null);

}

public async Task StartListenAsync(CultureInfo culture, CancellationToken cancellationToken)

{

await Task.Delay(1000, cancellationToken);

CurrentState = SpeechToTextState.Listening;

StateChanged?.Invoke(this, new SpeechToTextStateChangedEventArgs(CurrentState));

Device.StartTimer(TimeSpan.FromSeconds(1), () =>

{

RecognitionResultUpdated?.Invoke(this, new SpeechToTextRecognitionResultUpdatedEventArgs(new SpeechToTextRecognitionResult("Simulated intermediate result.")));

return true;

});

}

public async Task StopListenAsync(CancellationToken cancellationToken)

{

await Task.Delay(500, cancellationToken);

CurrentState = SpeechToTextState.Stopped;

StateChanged?.Invoke(this, new SpeechToTextStateChangedEventArgs(CurrentState));

RecognitionResultCompleted?.Invoke(this, new SpeechToTextRecognitionResultCompletedEventArgs(new SpeechToTextRecognitionResult("Simulated final result.")));

}

public async Task<bool> RequestPermissions(CancellationToken cancellationToken)

{

await Task.Delay(500, cancellationToken);

return true;

}

public ValueTask DisposeAsync()

{

return ValueTask.CompletedTask;

}

}
