I've made a Simple Program That Recognizes Speech Using SAPI 5.4 , i wanted to ask if i can add some more languages to the TTS and The ASR , Thanks Here is the code i made you anybody needs to take a look at it
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 SpeechLib;
using System.Globalization;
using System.Speech.Recognition;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
// Speech Recognition Object
SpSharedRecoContext listener;
// Grammar object
ISpeechRecoGrammar grammar;
public Form1()
{
InitializeComponent();
}
public string ps;
private void button1_Click(object sender, EventArgs e)
{
if (btnListen.Text == "Start Listening")
{
try
{
listener = new SpeechLib.SpSharedRecoContext();
listener.Recognition += new _ISpeechRecoContextEvents_RecognitionEventHandler(listener_Reco);
grammar = listener.CreateGrammar(0);
grammar.DictationLoad("", SpeechLoadOption.SLOStatic);
grammar.DictationSetState(SpeechRuleState.SGDSActive);
btnListen.Text = "Stop Listening";
if (ps == "1")
{
listener.Resume();
ps = "0";
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
else if (btnListen.Text == "Stop Listening")
{
listener.Pause();
btnListen.Text = "Start Listening";
if (ps == "0")
{
ps = "1";
}
}
}
public void listener_Reco(int StreamNumber, object StreamPosition, SpeechRecognitionType RecognitionType, ISpeechRecoResult Result)
{
string heard = Result.PhraseInfo.GetText(0, -1, true);
textBox1.Text += " " + heard;
}
private void button1_Click_1(object sender, EventArgs e)
{
WinXP winxp = new WinXP();
winxp.Show();
this.Hide();
}
string getOSInfo()
{
//Get Operating system information.
OperatingSystem os = Environment.OSVersion;
//Get version information about the os.
Version vs = os.Version;
//Variable to hold our return value
string operatingSystem = "";
if (os.Platform == PlatformID.Win32Windows)
{
//This is a pre-NT version of Windows
switch (vs.Minor)
{
case 0:

break;
case 10:
if (vs.Revision.ToString() == "2222A")
operatingSystem = "98SE";
else

break;
case 6:
if (vs.Minor == 0)
operatingSystem = "Vista";
else
operatingSystem = "7";
break;
default:
break;
}
}
//Make sure we actually got something in our OS check
//We don't want to just return " Service Pack 2" or " 32-bit"
//That information is useless without the OS version.
if (operatingSystem != "")
{
//Got something. Let's prepend "Windows" and get more info.
operatingSystem = "Windows " + operatingSystem;
//See if there's a service pack installed.
if (os.ServicePack != "")
{
//Append it to the OS name. i.e. "Windows XP Service Pack 3"
operatingSystem += " " + os.ServicePack;
}
//Append the OS architecture. i.e. "Windows XP Service Pack 3 32-bit"
operatingSystem += " " + getOSArchitecture().ToString() + "-bit";
}
//Return the information we've gathered.
return operatingSystem;
}
int getOSArchitecture()
{
string pa = Environment.GetEnvironmentVariable("PROCESSOR_ARCHITECTURE");
return ((String.IsNullOrEmpty(pa) || String.Compare(pa, 0, "x86", 0, 3, true) == 0) ? 32 : 64);
}
private void Form1_Load(object sender, EventArgs e)
{
string OS = getOSInfo();
if (OS.Contains("XP"))
{
btnXP.Visible = true;
}
else
{
btnXP.Visible = false;
btnYes2.Visible = true;
btnNo2.Visible = true;
btnNo.Visible = false;
btnYes.Visible = false;
}
}
}
}
P.S i've Had A Problem When Resuming The Recognizer
It depends a little bit on what you're doing with the recognizer. Yes, the desktop OSes (Windows Vista, 7) come with a recognizer that is tied to the language version of the OS. But, Microsoft also gives away for free (no weapon needed) a recognition engine for use on Servers (but can also be used on Desktop OSes). There are many different langauges available for free.
There are a few differences between the desktop and server recognizer libraries. My understanding is that the desktop recognizers are trainable for a specific speaker, support higher quality audio input, and include a dictation grammar. These are designed for desktop use where only one speaker is expected at a time. The server recognizers are designed for telephone quality audio, are not trainable, and require a limited grammar (no dictation). The server engines are designed for higher scale and multiple simultaneous speakers (like in IVR or SpeechServer applications).
