Problem with helloIntent: two results

“use strict”;

var Alexa = require(“alexa-sdk”);

var handlers = {
“HelloIntent”: function () {
this.response.speak(“Hello, Bob”);
this.emit(’:responseReady’);
},
“LaunchRequest”: function () {
this.response.speak(“bob, welcome to Codecademy”);
this.emit(’:responseReady’);
}
};

exports.handler = function(event, context, callback){
var alexa = Alexa.handler(event, context);
alexa.registerHandlers(handlers);
alexa.execute();
};

Whenever I plug this code(which I believe is correct) into the test option in the Alexa developer get two different effects. When I say “ask code academy to say hello” I get hello bob" (which is what I want) or “hello codecademy”(which i don’t want). I have no idea what I am doing wrong. I would love some feedback.
-Thanks
