edit:

i need piece of code:

case "listen":                     ai.speak("i listening");                     textbox1.text = textbox1.text + " " + e.result.text.tostring();                     break; 

when 'listen', ai follows "i listening". after should placing text im saying microphone in textbox1, doesnt. places 'listen' in it.

everything else works fine!

case "listen":     ai.speak("i listening");     textbox1.text = textbox1.text + " " + e.result.text.tostring();     break; 

e.result contains result obtained when user said "listen". need listen user again after make ai said "i listening".

case "listen":     ai.speak("i listening");     var result = srecognizer.recognize();     textbox1.text += " " + result.text;     break;
