Respected Members

Hi, first of all i must thanku all my fellow members for helping me so much in my problems, the help which i never expected this is my first experience with visual studio and because of you all u make it so easy and a fun to learn , i will soon learn more c# and start addressing question here , but till that time i request u to plz co-operate with me as i am still a learner and will always be ,

now i should stop posting a emotional movie script here and ask my doubt so here it is , i am struck on this i have this code:

using Microsoft.VisualBasic;
using System;
using System.Collections;
using System.Collections.Generic;
using System.Data;
using System.Diagnostics;
using System.Speech.Recognition

using System.ComponentModel;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Threading;

namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void Form1_Load(object sender, EventArgs e)
{
// Create a new SpeechRecognizer instance.
sr = new SpeechRecognizer()

// Create a simple grammar that recognizes "red", "green", or "blue".
Choices colors = new Choices();
colors.Add("red");
colors.Add("green");
colors.Add("blue");
colors.Add("white");

GrammarBuilder gb = new GrammarBuilder();
gb.Append(colors);

// Create the actual Grammar instance, and then load it into the speech recognizer.
Grammar g = new Grammar(gb);
sr.LoadGrammar(g);

// Register a handler for the SpeechRecognized event.
sr.SpeechRecognized += new EventHandler(sr_SpeechRecognized);
}

// Simple handler for the SpeechRecognized event.
private void sr_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
{
if(e.Result.Text=="Red");
MessageBox.Show(e.Result.Text);
}

private SpeechRecognizer sr;

Now in my application i need to judge numbers 1 to 6 that is when user say number 3 than it should in a string like this ("#3");

Now after this user again speaks something from 500, 1500, 2500 and it advances the previous string to this if he say 1500
("#3 P1500);

This is what i really want , i will add this 1to 6 and 500, 1500, 2500 to my grammar , thats i know but i dont know how after one if detected my system will again look for another work i dont have much knowledge with stirngs also plz help me with that also,

Once again i am a starter so i request you to a give a detail solution.

Thanks in advance

Accepted answer
I don't know much about speech recognition but, after adding those numbers to your grammar, I'd have thought that your SpeechRecognized event handler needs to look something like this:

// Add this field to form
private string command = "#";

// Simple handler for the SpeechRecognized event.
private void sr_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
{
if (command == "#")
{
switch (e.Result.Text)
{
case "One":
command += "1 P";
return;
case "Two":
command += "2 P";
return;
case "Three":
command += "3 P";
return;
case "Four":
command += "4 P";
return;
case "Five":
command += "5 P";
return;
case "Six
command += "6 P";
return;
default:
MessageBox.Show("Please speak a number between one and six");
return;
}
}
else if (command.Length == 4)
{
switch (e.Result.Text)
{
case "Five Hundred":
command += "500";
return;
case "One Thousand Five Hundred":
command += "1500";
return;
case "Two Thousand Five Hundred":
command += "2500";
return;
default:
MessageBox.Show("Please speak one of these numbers: 500, 1500 or 2500");
return;
}
MessageBox.Show("Please wait until previous command is processed");
}

I'm assuming here that if the words are spoken quickly enough and then there's a pause that the event will only fire once and return all the words spoken.

So, therefore the event will be fired twice - once for the number spoken from one to six, followed by a pause, and then again for the number spoken after 'P'.

Assuming this will work, whatever method processes the command should reset it to "#" after it's finished.

I'd start a new thread for that as it's really a completely different topic from this one.

deepender singla15y ago
done , in future will only marked only one as answer.
Vulpes15y ago
deepender,

Pleased to hear it's working OK now :)

Incidentally, would you mind trying to reduce the number of 'Accepted Answers' in this and your previous thread (http://www.c-sharpcorner.com/Forums/Thread/132947/how-to-use-value-recieved-in-console-application-in-other-pr.aspx) to just one as we're only supposed to get one per thread.

Usually, when you attempt to mark another post in the same thread as an Accepted Answer, the first Accepted Answer is removed so there must be a bug in the system somewhere.

Many thanks :)

Respected sir thanks i have'nt used process.command ; just put a forever for lopp above first if and it is working fine and testing is finished working very fine with motors.

In C# methods must be entirely separate from each other - you can't nest one method within another. Also methods must always be part of a class or struct - they can't stand on their own.

So, just place it after the previous method:

private void sr_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
{
if (command == "#")
{
switch (e.Result.Text)
{
case "One":
command += "1 P";
return;
case "Two":
command += "2 P";
return;
case "Three":
command += "3 P";
return;
case "Four":
command += "4 P";
return;
case "Five":
command += "5 P";
return;
case "Six
command += "6 P";
return;
default:
MessageBox.Show("Please speak a number between one and six");
return;
}
}
else if (command.Length == 4)
{
switch (e.Result.Text)
{
case "Five Hundred":
command += "500";
break;
case "One Thousand Five Hundred":
command += "1500";
break;
case "Two Thousand Five Hundred":
command += "2500";
break;
default:
MessageBox.Show("Please speak one of these numbers: 500, 1500 or 2500");
return;
}
ProcessCommand(); // need to add this method
command = "#"; // reset command
}
MessageBox.Show("Please wait until previous command is processed"); // might not need this line now
}

private void ProcessCommand()
{
MessageBox.Show(command);
}

i got error like:
Error2Type or namespace definition, or end-of-file expectedE:\Documents\Visual Studio 2010\Projects\WindowsFormsApplication1\WindowsFormsApplication1\Form1.cs14439WindowsFormsApplication1

may be i have created a mess in a program i am not able to judge where do i need to add this function processcommand and what shoukd i need to add and were i call this function , plz help i ahve tries a lot but not able to judge basically i am quite new with c#. sir plz help
Vulpes15y ago
Just add a method to your form. The following should suffice for testing purposes:

private void ProcessCommand()
{
MessageBox.Show(command);
}

However, these look like the commands you were using in your SerialPort program so I imagine that you'll need to add code to write them to the port.
deepender singla15y ago
sir i dont understand processcommnad how i will make it , plz reply a detail explanation , do i need to create like function we create in c
Vulpes15y ago
In that case you'll need to call a method to do the processing when the command is complete and then reset it to "#".

I'd try changing the code I suggested earlier to the following:

private void sr_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
{
if (command == "#")
{
switch (e.Result.Text)
{
case "One":
command += "1 P";
return;
case "Two":
command += "2 P";
return;
case "Three":
command += "3 P";
return;
case "Four":
command += "4 P";
return;
case "Five":
command += "5 P";
return;
case "Six
command += "6 P";
return;
default:
MessageBox.Show("Please speak a number between one and six");
return;
}
}
else if (command.Length == 4)
{
switch (e.Result.Text)
{
case "Five Hundred":
command += "500";
break;
case "One Thousand Five Hundred":
command += "1500";
break;
case "Two Thousand Five Hundred":
command += "2500";
break;
default:
MessageBox.Show("Please speak one of these numbers: 500, 1500 or 2500");
return;
}
ProcessCommand(); // need to add this method
command = "#"; // reset command
}
MessageBox.Show("Please wait until previous command is processed"); // might not need this line now
}
deepender singla15y ago
when one command like ("#1 P500) gets complete it starts for new command automatically
Vulpes15y ago
When a user has spoken the whole command, how do you go about processing it?

Does the user have to press a button or should the command be processed automatically and then wait for the next command?
deepender singla15y ago
at the time of testing i used this code i just a message box every where to see command now but there is problem with that it check for value of command one time next time i speak when the same program running it doesnot show i want it to detect again and again if a user say command for that i even added command = "#'; but that is not working it doesnot showing message box how i can do that , let me show you whole code.

the error is gone now , now testing begins and will soon post if it works or not
Vulpes15y ago
I generally place my fields at the top of the class so I can easily find them:

public partial class Form1 : Form
{
private string command = "#";

public Form1()
{
InitializeComponent();
}

// rest of code
}
deepender singla15y ago
sir , i have tried your solution where do i need to add

// Add this field to form
private string command = "#";

in my code i try adding at many places but it is showing error like plz tell me exact place wherei need to add . the
errors are when i add it private form load1
Error2The name 'command' does not exist in the current contextE:\Documents\Visual Studio 2010\Projects\WindowsFormsApplication1\WindowsFormsApplication1\Form1.cs7617WindowsFormsApplication1
like this how i can remove them.
