i'm trying call speak method of class texttospeech multiple times, not seem work - speaks last phrase each time.

string temp="abcd";         ss(temp);          string temp1="wxyz";          ss(temp1);          public void ss(string t){             tts.speak(t, texttospeech.queue_flush, null);       }
