Voice controll app in C#

csharp

In order to implement voice controll, i used System.Speech.Recognition library.

1using System.Speech.Recognition;
2using System.Speech.Synthesis;
3
4  private void Form1_Load(object sender, EventArgs e)
5        {
6            Choices  commands = new Choices();
7            commands.Add(new string[] { "stop livingroom",  "bedroom light on", "bedroom light off", "livingroom light on"})
8            GrammarBuilder  gBuilder = new GrammarBuilder();
9
10            gBuilder.Append(commands);
11
12            Grammar grammar = new Grammar(gBuilder);
13
14            recEngine.LoadGrammarAsync(grammar);
15            recEngine.SetInputToDefaultAudioDevice();
16            recEngine.SpeechRecognized  += recEngine_SpeechRecognized;
17
18
19            synthesizer.Volume = 100;  // 0...100
20            synthesizer.Rate = -2;     // -10...10
21        }

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

  private void Form1_Load(object sender, EventArgs e)
        {
            Choices  commands = new Choices();
            commands.Add(new string[] { "stop livingroom",  "bedroom light on", "bedroom light off", "livingroom light on"})
            GrammarBuilder  gBuilder = new GrammarBuilder();

            gBuilder.Append(commands);

            Grammar grammar = new Grammar(gBuilder);

            recEngine.LoadGrammarAsync(grammar);
            recEngine.SetInputToDefaultAudioDevice();
            recEngine.SpeechRecognized  += recEngine_SpeechRecognized;


            synthesizer.Volume = 100;  // 0...100
            synthesizer.Rate = -2;     // -10...10
        }
