I think there is no point to confuse with the remote web server and the browser where we are browsing and all.

 ss.SelectVoiceByHints(VoiceGender.Female);
                ss.Volume = 100;
                ss.Rate = -3;
                pb.ClearContent();
                pb.AppendText("Please answer all the Questions and you starts here!");
                ss.Speak(pb);
                Thread.Sleep(TimeSpan.FromMilliseconds(1000));

                pb.ClearContent();
                pb.AppendText(lbl1.Text);
                ss.Speak(pb);
                Thread.Sleep(TimeSpan.FromMilliseconds(1000));

                ss.SelectVoiceByHints(VoiceGender.Male);
                pb.ClearContent();
                pb.AppendText("Options are ");
                ss.Speak(pb);

                optiona = rblist1.Text;
                optionb = rblist2.Text;
                optionc = "Not Sure";

                pb.ClearContent();
                pb.AppendText(optiona);
                ss.Speak(pb);
                Thread.Sleep(TimeSpan.FromMilliseconds(700));

                pb.ClearContent();

                Choices clist = new Choices(new string[] { "Yes", "No", "Not Sure" });

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

                // Construct a Grammar object and load it to the recognizer.
                Grammar gr = new Grammar(gb);   
                sre.LoadGrammarAsync(gr); 
                sre.SetInputToDefaultAudioDevice();
                sre.RequestRecognizerUpdate();

                var result = sre.Recognize();

                if (result.Text == "Yes")
                {
                    rblist1.Checked = true; 
                    break;

                }                 
            }
