Voice recognition in Pt-BR

Question

How do I use Speech Recognition when my OS(Windows 8 x64) is in En-BR? I want to use commands in English.

I’m using the following code:

private void Form1_Load(object sender, EventArgs e)
        {
            SpeechRecognizer sr = new SpeechRecognizer();
            Choices commands = new Choices();
            commands.Add("hi", "test");

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

            Grammar g = new Grammar(gb);

            sr.LoadGrammar(g);

            sr.SpeechRecognized += new EventHandler<SpeechRecognizedEventArgs>(sr_SpeechRecognized);


        }

        void sr_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
        {
            textBox1.Text = e.Result.Text;
        }

But it makes a mistake in the sr.LoadGrammar(g)

An unhandled Exception of type 'System.Platformnotsupportedexception' occurred in System.Speech.dll

Additional information: No recognizer installed."

Answer 1

To change the language in the method SpeechRecognizer Theoretically I would have to use it this way:

private void Form1_Load(object sender, EventArgs e)
        {
            SpeechRecognizer sr = new SpeechRecognizer(new CultureInfo("pt-BR"));

However in Windows in Portuguese when Voce accesses this path:

• Control Panel > Ease of Access > Speech Recognition

And displayed this message:

Windows Speech recognition is not available for your current display language.

This is because according to this answer microsoft Answers. the Speech recognition is available only for the following languages: english (United States and United Kingdom), french, german, japanese, mandarin (simplified and traditional Chinese) and spaniard, as long as the Windows language is the above, that is, if your Windows language is portuguese, won’t work.
