Voice controll app in C#

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

Libraries used for server-side in Node Js

JavaScript
var app = require('express')();
var server = require('http').Server(app);
const SerialPort = require('serialport');
const Readline = require('@serialport/parser-readline');
var io = require('socket.io')(server);
var fs = require('fs');
