[Chocolade]

Im using windows 7 and Visucal c# Express edition 2008 with .Net 3.5

This is the code:



using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Speech;
using System.Speech.Synthesis;
using System.Speech.Recognition;
using System.Speech.Recognition.SrgsGrammar;

namespace Speech_Recognition
{
public partial class Form1 : Form
{

Choices myChoices;
GrammarBuilder myGrammerBuilder;
Grammar myGrammer;
SpeechSynthesizer mysynt;
SpeechRecognizer myspeech;
public Form1()
{
InitializeComponent();
myChoices = new Choices();
mysynt = new SpeechSynthesizer();
myspeech = new SpeechRecognizer();
myspeech.SpeechRecognized += rec_SpeechRecognized;


}

private void Form1_Load(object sender, EventArgs e)
{
myChoices.Add("please");
myGrammerBuilder = new GrammarBuilder(myChoices);
myGrammer = new Grammar(myGrammerBuilder);
myspeech.LoadGrammar(myGrammer);
myspeech.Enabled = true;


}
void rec_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
{
myLetters.Text = e.Result.Text;
}

}
}


I tried using my microphne but it dosent help i said please many times and nothing happened.

What did i do wrong? I thought its something to do with culture settings but i couldnt find how to set it up.



Thanks for helping

I dont directly see anything wrong with the code, nor have I any experience with this component.
There are how ever few things I would check:
- Is microphone recording anything at all
- Is this microphone set as default input device?
- or Must this app been told, which device to listen to?
- What is level of sound quality needed for recognition, and is this achieved?
- What happens if you try other words, or simple sounds "A", "B".. etc?
- Are there more events on these components you can subscribe to? Just to get more feeling what can be done.
- more?
