How to change speech recognition language

kinght moonlight

(sry for my English)

Hi everybody, I'm currently using WinXP, visual 2k5 + SAPI 5.1

While developing program using Speech SDK, I wouldn't find out way to change the current speech recognition language although I can get the list of languages supported.

  //SpSharedRecoContext RC = new SpSharedRecoContext();
            foreach (ISpeechObjectToken t
                     in RC.Recognizer.GetRecognizers(string.Empty, string.Empty))
            {
                string a = t.GetDescription(0);
                if (a == "Microsoft Japanese Recognizer v5.1")
                {
                    //I want to put the code that change the current language recognition here
                }
                comboBox1.Items.Add(a);
            }

I've searched in the internet for the solving my problem but I couldn't get the answer. Anyone help me?
Thanks in advance .

Did you ever find an answer? Years later there is still no information on how to do this.

Hi Mahesh Chand! thanks for our replying.

As the matter of fact I'm trying to develop a program for learning Japanese. it'd be easy if it is English, cause it is default engine. it's believed that not really accuracy but I do it for fun as well, Take a look at the picture below:

What I want is change the default recognition engine to another language instead of English... after that we speak and it can recognize and show the text that recognized into Textbox.

+ For another thing, there is no Japanese voice but Chinese only (sry if I misunderstood).

Many thanks.

You need to first create an InstalledVoice object for the voice you want to change it to. See how to get InstalledVoices here:

After that you need to call SelectVoice method of SpeechSynthesizer to set current voice.

This is how I would do in .NET 3.5. Whatever version you are using, you should have similar methods or properties.
