C# WinForms, Error while working with Microsoft.Speech?

Question

Microsoft

Good day friends, I only know basic knowledge of C # and I was interested in creating a simple program for speech recognition, I used the Microsoft.Speech library and downloaded all the data and the language pack, but I had a problem compiling programs, please tell me what could be problem:
Error:


Below is the code of the program:

private SpeechRecognitionEngine sre;
        private CultureInfo ci;

        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            try
            {
                ci = new CultureInfo("ru-RU");
                sre = new SpeechRecognitionEngine(ci);
                sre.SetInputToDefaultAudioDevice();

                sre.SpeechRecognized += new EventHandler<SpeechRecognizedEventArgs>(Sre_SpeechRecognized);

                Choices ch = new Choices();
                ch.Add(new string[]
                {
                    "Один",
                    "Два",
                    "Три"
                });

                GrammarBuilder gb = new GrammarBuilder();
                gb.Append(ch);
                Grammar g = new Grammar(gb);
                sre.LoadGrammar(g);
                sre.RecognizeAsync(RecognizeMode.Multiple);
            }
            catch(Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }

        private void Sre_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
        {
            if(e.Result.Confidence > 0.12)
            {
                MessageBox.Show(e.Result.Text);
            }
        }

Answer 1

Well, the error is not in the code, but in the fact that Microsoft.Speech is crooked. Reinstalling might help.
