SpeechSynthesizer & SpeechRecognizer

Question

Am enhancing en existing web application which makes the visually impaired people, to be used based on the Text to Speech & Speech Recognition

The same code is working fine in windows application, but not in web application.

If I put break point, it's coming to the point but the code is not getting execute.

Here is the code, please do the needful.

using System.Speech;
using System.Speech.Synthesis;
using System.Threading;
using System.Speech.Recognition;



 SpeechSynthesizer ss = new SpeechSynthesizer();
    PromptBuilder pb = new PromptBuilder();
    SpeechRecognitionEngine sre = new SpeechRecognitionEngine();
    SpeechRecognizer sr = new SpeechRecognizer();

   protected void btn_Spk_Click(object sender, EventArgs e)
    {

            RadioButton rblist1 = ((RadioButton)row.FindControl("rdTemp_Opt1"));
            RadioButton rblist2 = ((RadioButton)row.FindControl("rdTemp_Opt2"));
            RadioButton rblist3 = ((RadioButton)row.FindControl("rdTemp_Opt3"));
