Jarvis speech recognition problem

Question

    class Program
    {
        
        public SpeechRecognitionEngine recognitionEngine;
        string message;
        SpeechSynthesizer speaker = new SpeechSynthesizer();
        public static void Main(){
            Program prgrm = new Program();
            prgrm.Init();
          //process commands
            while (true)
            {
                
                prgrm.message=prgrm.recognise();
                prgrm.command(prgrm.message);
            }
            

        
        }
        public void Init()
        {
            recognitionEngine = new SpeechRecognitionEngine();
            recognitionEngine.SetInputToDefaultAudioDevice();
            recognitionEngine.SpeechRecognized += (s, args) =>
            {
                foreach (RecognizedWordUnit word in args.Result.Words)
                {
                    if (word.Confidence > 0.5f)
                        message += word.Text + " ";
                }

            };
            recognitionEngine.LoadGrammar(new DictationGrammar());
            Console.WriteLine(message);
        }
        public void speak(string message)
        {
            speaker.Rate = 1;
            speaker.Volume = 100;
            speaker.Speak(message);
        }
        public string recognise()
        {
            Console.WriteLine(message);
            
           
           
            recognitionEngine.RecognizeAsyncStop();
            return message;
        }
        public void command(string message)
        {
            switch (message)
            {
                case "hi":
                    speak("Hello Sir");
                    Console.WriteLine(message);
                    break;
                case "jarvis Chrome":
                    speak("Opening Google Chrome");
                    speak("Please Wait");
                    Console.WriteLine("Please Wait");
                    System.Diagnostics.Process.Start("google chrome.lnk");
                    break;
                case "jarvis time":
                    speak("Sir , The Time is " + DateTime.Now.ToString("h:mm tt"));
                    break;
                case "jarvis date":
                    speak("Sir , The Date is " + DateTime.Now.Date);
                    break;
                case "jarvis day":
                    speak("Sir, The Day is " + DateTime.Now.DayOfWeek);
                    break;
                case "thank you":
                    speak("You'r welcome sir");
                    break;
                case "":
                    break;
                default :
                    Console.WriteLine(message);
                    break;
            }
        



                   

        }

    }

This is my code

I want it to recognise things that I ask it but it just doesn't respond :(

I threw in some simple debuging statements to check the value of message but it doesn't work!

Answer 1

Before calling RecognizeAsyncStop() that stops the process, you probably has to start the recognition using  RecognizeAsync(), then wait. See the samples in Documentation for RecognizeAsync and RecognizeAsyncStop.

Answer 2

when i do put the RecogniseAsync statement it gives me an error saying that "process cannot be executed while recognition is in process"

Answer 3

Hi Hgoel0974,

  I feel you could read this article:
