Question

Hi i have situation here i don't know how to solve this. This code is fine with 0 Errors but whenever i do F5 it shows me a blank form with no voice and no recognition please help . Please i really need help can someone help me please.
Now this line is only for "it look like your post is mostly code; please add some more details";

using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Windows.Forms; using System.Speech.Synthesis; using System.Speech.Recognition; using System.Threading; namespace a.i { public partial class Form1 : Form { SpeechSynthesizer s = new SpeechSynthesizer(); Choices list = new Choices(); public Form1() { SpeechRecognitionEngine rec = new SpeechRecognitionEngine(); list.Add(new String[] { "hello", "how are you" }); Grammar gr = new Grammar(new GrammarBuilder(list)); try { rec.RequestRecognizerUpdate(); rec.LoadGrammar(gr); rec.SpeechRecognized += rec_SpeachRecognized; rec.SetInputToDefaultAudioDevice(); rec.RecognizeAsync(RecognizeMode.Multiple); } catch { return; } s.SelectVoiceByHints(VoiceGender.Neutral); s.Speak("Hello, my name is Gabriel ChatterBot"); InitializeComponent(); } public void say(string h) { s.Speak(h); } private void rec_SpeachRecognized(object sender, SpeechRecognizedEventArgs e) { String r = e.Result.Text; //what you say if (r == "hello") { // what it says say("hi"); } //what you say if (r == "how are you") { // what it says say("Great, and you!"); } } } }

Most likely there is an exception thrown in the constructor. Due to the return in the catch block InitializeComponents is not called... — Thomas Voß

I don't know what type of problem your code has, but try replaceing catch { return; } with catch Exception ex {MessageBox.Show(ex.ToString();}. This will show you if you have an Exception throw in your try block. For further help it would be helpful if you poste that message. — Thomas Voß

@ThomasVoß it worked but now it's saying System.InvalidOperationException “The language for the grammar does not match the language of the speech recognizer” what should i do? — Gabriel Brandao

From the exception you posted, I think that you have not initionalized the Grammar and SpeechRecognitionEngine correctly. It seems that you need to specify a language / culture for it. From the documentation at: https://msdn.microsoft.com/en-us/library/hh378426(v=office.14).aspx

// Create a new SpeechRecognitionEngine instance. SpeechRecognitionEngine sre = new SpeechRecognitionEngine(new System.Globalization.CultureInfo("en-US"));
