Voice Recognition with Java and C#

In previous post, I mentioned AIML. It's an AI ChatBot to digest natural language chat. I am always think it's cool to combine with Voice Recognition. Thus, people can be not only asking the ChatBot quesion for the answer but also asking AI ChatBot to "do something". Here is an example that the Voice activation with system (US Pizza Papa John’s allows to order pizza via Voice System, same with their supply chain system :http://www.papajohns.com/ordering/mobile.shtm, http://www.mmh.com/article/papa_johns_fresh_take_on_wms_and_voice_technology )

I spent my weekend and try a little bit voice recognition on demo with Java and C#, here are the details.

(PS: It’s better you try this in Meeting Room by alone or at your home, otherwise when you test, you will look like idiot )    J

Java Version

---------------

Preparation: 

----------------

JDK 8 ( J2EE )

Eclipse SDK ( LUNA )

Sphinx4 : http://cmusphinx.sourceforge.net/wiki/download/

JSAPI ( Included in Sphinx 4 : jsapi.jar)

1.       Create a java project and add jars

2.       Test HelloWorld.jar

3.       Try Hello World Source Code

a.       HelloWorld.java

b.      hello.gram ( grammer file )

c.       helloworld.config.xml ( config file )

4.       I added new recognition grammer “Hey Johnny” in *.gram

Modified *.java showing in command line.

5.       I don’t wanna change config.xml now so I follow whatever in manifest/config first. ( add one more jar into UserLib ). Now it’s working

Last: I can duplicate this voice recognition to trigger “Check Vagrant Version” with my Java ChatBot. Then it will trigger check vagrant version cli.

C# version, here has full example.

add  System.Speech reference

Here is form1.cs example:

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Speech.Recognition;

        {

            InitializeComponent();

        }

        private void Form1_Load(object sender, EventArgs e)

        {

            Choices commands = new Choices();

            commands.Add(new string[] { "Say Hello", "Print My Name", "Love You", "Please Check My System" });

            GrammarBuilder gBuilder = new GrammarBuilder();

            gBuilder.Append(commands);

            Grammar grammer = new Grammar(gBuilder);

            recEngine.LoadGrammarAsync(grammer);

            recEngine.SetInputToDefaultAudioDevice();

            recEngine.SpeechRecognized +=recEngine_SpeechRecognized;

           

        }

                    break;

                default:

                    break;

            }

            //throw new NotImplementedException();

        }

    }
