Hello,

Welcome to Microsoft Q&A.

We can judge whether it has completed the recognition by the state change of SpeechRecognizer

private SpeechRecognizer speechRecognizer;
public MainPage()
{
    this.InitializeComponent();
    this.speechRecognizer = new SpeechRecognizer();
    speechRecognizer.StateChanged += SpeechRecognizer_StateChanged;
}

private void SpeechRecognizer_StateChanged(SpeechRecognizer sender, SpeechRecognizerStateChangedEventArgs args)
{
    if(args.State== SpeechRecognizerState.SoundEnded)
    {
        // The subsequent input of audio is not detected, 
        // which can be understood as the speaker has finished speaking, 
        // but SpeechRecognizer has not stopped audio monitoring
    }
    else if(args.State==SpeechRecognizerState.Idle)
    {
        // SpeechRecognizer stops listening
    }
    else if (args.State == SpeechRecognizerState.Paused)
    {
        // (Used for continuous recognition state) SpeechRecognizer pause is recognition
    }
}

You can modify the above code according to your needs, and start DispatcherTimer in the state you need.

Thanks.
