Stimmerkennung in C#?

Hallo liebe Community!

Ich habe einen C# Quellcode heruntergeladen. Das fertige Programm sollte ein Speech to Text tool werden. Jedoch zeigt mir Visual Studio zwei Fehler an, welche mich vom compilieren hindern.

Die Fehler lauten:

Severity Code Description Project File Line Suppression State

Error CS8652 The feature 'top-level statements' is currently in Preview and *unsupported*. To use Preview features, use the 'preview' language version. atletik C:\Users\herrb\Documents\aletik_c#\atletik\atletik\Program.cs 5 Active

Severity Code Description Project File Line Suppression State

Error CS0106 The modifier 'private' is not valid for this item atletik C:\Users\herrb\Documents\aletik_c#\atletik\atletik\Program.cs 11 Active

Hier mal der Quellcode:

using System.Speech;
using System.Speech.Recognition;
using System;


SpeechRecognitionEngine recognizer = null;
recognizer = new SpeechRecognitionEngine();
recognizer.SetInputToDefaultAudioDevice();
recognizer.SpeechRecognized += new EventHandler<SpeechRecognizedEventArgs>(recognizer_SpeechRecognized);
recognizer.RecognizeAsync(RecognizeMode.Multiple);


private void recognizer_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
{
    string text = e.Result.Text;
    Console.WriteLine(text);
}

Hätte jemand vielleicht eine Idee, ich kenne mich noch nicht in C# aus, deshalb frage ich. Eigentlich wollte ich nur dieses Tool und nicht mehr... also nicht mit C# arbeiten usw.

Das:

SpeechRecognitionEngine recognizer = null;
recognizer = new SpeechRecognitionEngine();
recognizer.SetInputToDefaultAudioDevice();
recognizer.SpeechRecognized += new EventHandler<SpeechRecognizedEventArgs>(recognizer_SpeechRecognized);
recognizer.RecognizeAsync(RecognizeMode.Multiple);

gehört in den Körper einer Methode oder eines Konstruktors.

Beide Methoden (also auch recognizer_SpeechRecognized) gehören folgend in eine Klasse.

Es könnte bspw. so aussehen:

using System.Speech;
using System.Speech.Recognition;
using System;

namespace MySpeechProject
{
  class Program
  {
    public static void Main()
    {
      var recognizer = new SpeechRecognitionEngine();
      recognizer.SetInputToDefaultAudioDevice();
      recognizer.SpeechRecognized += Recognizer_SpeechRecognized;
      recognizer.RecognizeAsync(RecognizeMode.Multiple);
    }

    private static void Recognizer_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
    {
      var text = e.Result.Text;
      Console.WriteLine(text);
    }
  }
}
