c# - Adding voice to my text -


i trying add voice calculator project. able add voice. facing problem. when press 13, first says "one" says "thirteen". , 1 more thing unable add voice equal(=) sign.

private void numberbuttons(object sender, eventargs e) {     button b = sender button;     if ((b == null) || (b.text == "0" && buffer.length == 0))         return;     buffer += b.text;     txtoutput.text = buffer;     if (txtoutput.text != "")     {         spvoice voice = new spvoice();         voice.volume = 100;         voice.speak(txtoutput.text, speechvoicespeakflags.svsflagsasync);     } }

here's method.

private void equal(object sender, eventargs e)  {      if (buffer.length != 0)          operand[1] = double.parse(buffer);      switch (op)      {          case '+': result = operand[0] + operand[1]; break;          case '-': result = operand[0] - operand[1]; break;          case '*': result = operand[0] * operand[1]; break;         case '/': result = operand[0] / operand[1]; break;      }      txtoutput.text = result.tostring();     if (txtoutput.text != "")     {         spvoice voice = new spvoice();         voice.volume = 100;         // voice.speak("the result is"+ speechvoicespeakflags.svsflagsasync);         voice.speak(txtoutput.text, speechvoicespeakflags.svsflagsasync);     }     step = 1;      buffer = "";  }

here's equal method.

you have convert numbers words, otherwise it'll 13 1 three. here's post shows how that.

also, equal need add manually text want spoken.

basically need build text this, operationtext "plus" or "minus", etc.:

  var texttobespoken =  input1toword + operationtext + input2toword + "equals" + resulttoword
