Recognition and Pause Console

Good morning. I have a console application made in C # for speech recognition with the class System.Speech.Recognition that recognizes the audio and writes it in a document called tub.txt. Here the code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Speech.Recognition;
using System.IO;

namespace VoiceRecognitionForIvernAppConsole
{
    class Program
    {
        static void Main(string[] args)
        {
            SpeechRecognitionEngine listen = new SpeechRecognitionEngine();
            listen.SetInputToDefaultAudioDevice();
            listen.LoadGrammar(new DictationGrammar());
            listen.SpeechRecognized += new EventHandler<SpeechRecognizedEventArgs>(reader);
            listen.RecognizeAsync(RecognizeMode.Multiple); 
        void reader(object sender, SpeechRecognizedEventArgs e)
        {
            TextWriter file;
            file = new StreamWriter("tub.txt");
            foreach (RecognizedWordUnit word in e.Result.Words)
            {
                file.WriteLine(word.Text + " ");
                Console.Write(word.Text + " ");
            }
            file.Close();
        }
        Console.ReadKey();
        }
    }
}

My problem is that when I finish speaking I must press a key obviously the command Console.ReadKey (); Otherwise, the application opens and closes immediately. I just want the app not to close until I hear something, a word or a sentence, then if it can be closed, without having to press a key. If not wait, listen, write in the document and close later. Nor would I put something with an if (word.Text.Equals ("quit")) because I just want to say maybe "Hello world" and then close. I read the documentation but I did not see a utility like that. Or I do not know if I'll be overlooking it. If someone has an idea, I thank them in advance.
