How do I handel events like speech or key press in C# Servic

I am trying to make a program basically a voice support so that recognizes speech and does the corresponding work I want this program to work even after the pc is in sleep state thats why i want service but after installing service successfully it does not hear any voice.

public partial class Service1 : ServiceBase
{
SpeechSynthesizer s = new SpeechSynthesizer();
SpeechRecognitionEngine rec = new SpeechRecognitionEngine();
Choices list = new Choices();
public Service1()
{
s.SelectVoiceByHints(VoiceGender.Male)
s.Speak("heyy");
list.Add(new String[] { "hello", "how are you" });
Grammar gr = new Grammar(new GrammarBuilder(list));
try
{
rec.RequestRecognizerUpdate();
rec.LoadGrammar(gr);
rec.SpeechRecognized += rec_speachrecocnized;
rec.SetInputToDefaultAudioDevice();
rec.RecognizeAsync(RecognizeMode.Multiple);
}
catch { return; };
InitializeComponent();
}
public void speak(String h)
{
s.Speak(h);
}
private void rec_speachrecocnized(object sender, SpeechRecognizedEventArgs e)
{
String r = e.Result.Text;
if (r == "hello")
{
speak("hello");
}
if (r == "how are you")
{
speak("fine");
}
}
protected override void OnStart(string[] args)
{
}
protected override void OnStop()
{
}
}
