Hi, I have a C # project that I want to add to that unique voice recognition feature.
Can I add this feature to my C# project using OpenCV or other tools?

What I have tried:

So far, I've only been able to implement a text-sensitive voice recognition program, but that's not enough because it's not sensitive to a specific sound:

public partial class EnVoiceUC : UserControl
    {
        public EnVoiceUC()
        {
            InitializeComponent();
        }
        string[] dialogs = Program.dlgArr;
        private void Recorder_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
        {
            Form1 f1 = new Form1();
            string recText = e.Result.Text;
            for (int i = 0; i < dialogs.Length; i++)
            {
                if(dialogs[i]==recText)
                {
                    try
                    {
                        ((Form)this.TopLevelControl).Hide();
                        f1.ShowDialog();
                        ((Form)this.TopLevelControl).Close();
                    } catch {;}
                }
            }
        }

        private void DoRecord_Click(object sender, EventArgs e)
        {
            System.Media.SystemSounds.Beep.Play();
            VoiceRecorder(true);
        }

        public void VoiceRecorder(bool enable)
        {
            Choices voices = new Choices();
            SpeechRecognitionEngine recorder = new SpeechRecognitionEngine();
            voices.Add(dialogs);
            Grammar gramer = new Grammar(new GrammarBuilder(voices));
            label2.Visible = enable;
            if (enable)
            {
                try
                {
                    recorder.RequestRecognizerUpdate();
                    recorder.LoadGrammar(gramer);
                    recorder.SpeechRecognized += Recorder_SpeechRecognized;
                    recorder.SetInputToDefaultAudioDevice();
                    recorder.RecognizeAsync(RecognizeMode.Multiple);
                }
                catch { return; }
            }
            else
            {
                try { recorder.UnloadGrammar(gramer); } catch { return; }
            }
        }
    }
