RaceOnRCWCleanup when running console app for speech recognition

I don't know either we can create a console app or not for speech recognition(searched for the same but didn't find any answer)and tried this code.
I have this code working in winforms app
but when trying to create this app in console visual studio is giving a very strange error mscorelib.pdb not found.And transferring to a page mscorelib.pdb

clist.Add(new string[] { "how are you", "what is the current time", "open chrome", "hello" });
Grammar gr = new Grammar(new GrammarBuilder(clist));
sre.RequestRecognizerUpdate();
sre.LoadGrammar(gr);
sre.SetInputToDefaultAudioDevice();
sre.SpeechRecognized += sre_recognised;
sre.RecognizeAsync(RecognizeMode.Multiple);
}
public void sre_recognised(object sender, SpeechRecognizedEventArgs e)
{
switch (e.Result.Text.ToString())
{
case "hello":ss.SpeakAsync("Hello shekar");
break;
case "how are you": ss.SpeakAsync("I am fine and what about you");
break;
case "what is the time":ss.SpeakAsync("current time is: " + DateTime.Now.ToString());
break;
case "open chrome":System.Diagnostics.Process.Start("chrome", "wwe.google.com");
break;
default: ss.SpeakAsync("thank you");
break;
}
Console.WriteLine(e.Result.Text.ToString());
}
}
}
here is the snapshot of the error page
I also loaded the given option "Microsoft.symbol.Server", but it is still giving the same output.
EDIT
HERE is the output window
Outputs are of big lengths ,so not being able to show all the outputs ,captured some relevant parts (regret).

You're seeing the debugger issuing a RaceOnRCWCleanup. The reason may be that you are instantiating but not properly cleaning up COM objects created under the hood by SpeechSynthesizer and/or SpeechRecognitionEngine.
At the same time, a Console application is not automatically 'kept alive'. You need to specifically add code to prevent it from exiting immediately.
You need to do 2 things:
Ensure your application stays alive long enough (for example, by adding a Console.ReadLine() statement in the Main method
Make sure that resources are properly cleaned up. Both SpeechRecognitionEngine and SpeechSynthesizer implement IDisposable, so they should be disposed when no longer needed. To do this properly, implement IDisposable in your tester class:
Example:
public class Tester
{
SpeechSynthesizer ss = new SpeechSynthesizer();
SpeechRecognitionEngine sre = new SpeechRecognitionEngine();
public void Dispose()
{
ss.Dispose();
sre.Dispose();
}
}

linking Microsoft.Speech with xamarin

I'm trying to link a microphone in a mobile phone which uses android and trying to achieve voice recognition and tts. I want to use Microsot.Speech library, the thing is that how can I access the microphone.
please have a look at this sample code from microsoft's website:
using System;
using Microsoft.Speech.Recognition;
namespace SpeechRecognitionApp
{
class Program
{
static void Main(string[] args)
{
// Create a SpeechRecognitionEngine object for the default recognizer in the en-US locale.
using (
SpeechRecognitionEngine recognizer =
new SpeechRecognitionEngine(
new System.Globalization.CultureInfo("en-US")))
{
// Create a grammar for finding services in different cities.
Choices services = new Choices(new string[] { "restaurants", "hotels", "gas stations" });
Choices cities = new Choices(new string[] { "Seattle", "Boston", "Dallas" });
GrammarBuilder findServices = new GrammarBuilder("Find");
findServices.Append(services);
findServices.Append("near");
findServices.Append(cities);
// Create a Grammar object from the GrammarBuilder and load it to the recognizer.
Grammar servicesGrammar = new Grammar(findServices);
recognizer.LoadGrammarAsync(servicesGrammar);
// Add a handler for the speech recognized event.
recognizer.SpeechRecognized +=
new EventHandler<SpeechRecognizedEventArgs>(recognizer_SpeechRecognized);
// Configure the input to the speech recognizer.
recognizer.SetInputToDefaultAudioDevice();
// Start asynchronous, continuous speech recognition.
recognizer.RecognizeAsync(RecognizeMode.Multiple);
// Keep the console window open.
while (true)
{
Console.ReadLine();
}
}
}
// Handle the SpeechRecognized event.
static void recognizer_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
{
Console.WriteLine("Recognized text: " + e.Result.Text);
}}}
I think that the line of interest here is:
recognizer.SetInputToDefaultAudioDevice();
how can I change input to be device microphone?
many thanks.
note: I copied the code above from: https://msdn.microsoft.com/en-us/library/office/microsoft.speech.recognition.speechrecognitionengine(v=office.14).aspx

Running Python Script/application in Windows Phone 8

I want to run the Skeinforge slicer program written in Python inside my Windows Phone 8 C# application. I have determined that I should probably use IronPython to do this, I have already determined that I can run Skeinforge inside the ipy.exe terminal I got when I installed IronPython. My problem though is that I am struggling to figure out how to host and run a Python script with IronPython inside Windows Phone 8. I have also already managed to get a simple hello world script running inside a Desktop Windows Forms application that transfers the applications console output to the Debug console with the following code:
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.Diagnostics;
using System.IO;
using IronPython.Hosting;
using Microsoft.Scripting.Hosting;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
DebugWriter debugW = new DebugWriter();
Console.SetOut(debugW);
}
private void button1_Click(object sender, EventArgs e)
{
TextWriter tw = new StreamWriter("Test.py");
tw.Write(scriptBox.Text);
tw.Close();
try
{
var ipy = Python.CreateRuntime();
dynamic test = ipy.UseFile("Test.py");
}
catch (Exception ex)
{
Debug.WriteLine("Error: " + ex.Message);
}
}
}
}
And this is the DebugWriter:
class DebugWriter : TextWriter
{
private StringBuilder content = new StringBuilder();
public DebugWriter()
{
Debug.WriteLine("Writing console to debug");
}
public override void Write(char value)
{
base.Write(value);
if (value == '\n')
{
Debug.WriteLine(content.ToString());
content = new StringBuilder();
}
else
{
content.Append(value);
}
}
public override Encoding Encoding
{
get { return System.Text.Encoding.UTF8; }
}
}
I have no idea how to even add the IronPython libraries to my Windows Phone 8 application though as the standard libraries won't import. I have though tried compiling the apparently now defunct Windows Phone 7 libraries with the master source code and I can import these libraries, but I get absolutely no response on the debug terminal when I try to run my hello world script.
Do any of you have any idea how to get this woring in Windows Phone 8, if you know how to do this in Windows 8/Metro/RT then that would also probably work for WP8.
UPDATE:
I have looked at the debug output again and I seem to get this error when trying to use the WP7 libraries to run a hello world script:
A first chance exception of type 'System.NotImplementedException' occurred in Microsoft.Scripting.DLL
Error: The method or operation is not implemented.

I managed to get Skeinforge running on a modified version of IPY. You can get the source for my application here: http://skeinforgewp8.codeplex.com/

how I can change the voice synthesizer gender and age in C#?

I would like to change the gender and age of the voice of System.Speech in c#. For example, a girl of 10 years but can not find any simple example to help me adjust the parameters.

First, check which voices you have installed by enumerating the GetInstalledVoices method of the SpeechSynthesizer class, and then use SelectVoiceByHints to select one of them:
using (SpeechSynthesizer synthesizer = new SpeechSynthesizer())
{
// show installed voices
foreach (var v in synthesizer.GetInstalledVoices().Select(v => v.VoiceInfo))
{
Console.WriteLine("Name:{0}, Gender:{1}, Age:{2}",
v.Description, v.Gender, v.Age);
}
// select male senior (if it exists)
synthesizer.SelectVoiceByHints(VoiceGender.Male, VoiceAge.Senior);
// select audio device
synthesizer.SetOutputToDefaultAudioDevice();
// build and speak a prompt
PromptBuilder builder = new PromptBuilder();
builder.AppendText("Found this on Stack Overflow.");
synthesizer.Speak(builder);
}

Did you take a look at this ?

first you need to intialise the reference speech using the add reference.
then create an event handler for the speak started then you can edit the paramemters inside that handler.
in the handler is where you can change the voice and age using the
synthesizer.SelectVoiceByHints(VoiceGender.Male , VoiceAge.Adult);

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; // first import this package
namespace textToSpeech
{
public partial class home : Form
{
public string s = "pran"; // storing string (pran) to s
private void home_Load(object sender, EventArgs e)
{
speech(s); // calling the function with a string argument
}
private void speech(string args) // defining the function which will accept a string parameter
{
SpeechSynthesizer synthesizer = new SpeechSynthesizer();
synthesizer.SelectVoiceByHints(VoiceGender.Male , VoiceAge.Adult); // to change VoiceGender and VoiceAge check out those links below
synthesizer.Volume = 100; // (0 - 100)
synthesizer.Rate = 0; // (-10 - 10)
// Synchronous
synthesizer.Speak("Now I'm speaking, no other function'll work");
// Asynchronous
synthesizer.SpeakAsync("Welcome" + args); // here args = pran
}
}
}
It'll be better choice to use "SpeakAsync" because when "Speak" function is executing/running none of other function will work until it finishes it's work (personally recommended)
Change VoiceGender
Change VoiceAge

These age and gender is actually of no use. If you have many voices installed in your windows, then you may call specific voices by these parameters. Otherwise, its simply fake!

troubles with running SlimDX C# application on Windows XP machine

I've made a simple C# WinForms app, which makes a screen-capture
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using SlimDX.Direct3D9;
using SlimDX;
namespace KMPP
{
public class DxScreenCapture
{
Device d;
public DxScreenCapture()
{
PresentParameters present_params = new PresentParameters();
present_params.Windowed = true;
present_params.SwapEffect = SwapEffect.Discard;
d = new Device(new Direct3D(), 0, DeviceType.Hardware, IntPtr.Zero, CreateFlags.SoftwareVertexProcessing, present_params);
}
public Surface CaptureScreen()
{
Surface s = Surface.CreateOffscreenPlain(d, Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height, Format.A8R8G8B8, Pool.Scratch);
d.GetFrontBufferData(0, s);
return s;
}
}
}
now to call it:
using System;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Runtime.InteropServices;
using System.IO;
using System.Collections.Generic;
using System.Collections.ObjectModel;
using SlimDX.Direct3D9;
using SlimDX;
using KMPP;
using System.Diagnostics;
using System.Threading;
namespace dxcapture
{
public partial class Form1 : Form
{
DxScreenCapture sc = new DxScreenCapture();
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
Stopwatch stopwatch = new Stopwatch();
DateTime current = DateTime.Now;
string n = string.Format(#"text-{0:yyyy-MM-dd_hh-mm-ss-tt}.bmp",DateTime.Now);
string directory = (#"C:\temp\");
string name = (".bmp");
string filename = String.Format("{0:hh-mm-ss}{1}", DateTime.Now, name);
string path = Path.Combine(directory, filename);
stopwatch.Start();
Thread.Sleep(1000);
Surface s = sc.CaptureScreen();
Surface.ToFile(s, path, ImageFileFormat.Bmp);
stopwatch.Stop();
s.Dispose();
textBox1.Text = ("Elapsed:" + stopwatch.Elapsed.TotalMilliseconds);
}
private void button2_Click(object sender, EventArgs e)
{
}
}
}
Everything works fine when I run this app on Windows 7 x64 (it was compiled here)
Unfortunately, when I try to run this app on Windows XP x86 machine - I'm getting following error:
How I tried to fix it?
installed latest DX on WinXP
installed latest SlimDX on WinXP (btw this step solved my previous problem)
installed latest .Net Framework v.4 on WinXP
compiled this app as x86 and used SlimDX.dll x86 for the same reason
I also put slimdx.dll into the same folder where dxcapture.exe (app name) is located
What might be the problem? Does WinXP support Directx9 screen capture?
edit: I've tried to comment-out different code-lines and it seems like "device creation" is the problem.. I mean this line:
d = new Device(new Direct3D(), 0, DeviceType.Hardware, IntPtr.Zero, CreateFlags.SoftwareVertexProcessing, present_params);
WinXP machine has integrated ATI graphics, so, I don't know.. maybe that's the problem, maybe not, but I can't check my program on some other pc.

As mentioned in the bug report you filed, the problem appears to be with your system, whether it be missing DirectX components or your graphics adapter not supporting Direct3D 9. If your card doesn't at least support D3D9, you won't be able to use SlimDX (or any of the other DirectX wrappers) for any kind of rendering.
