Accessing variables in different methods in TypeScript

Question

I've the below simple code, in which I have 2 variables defines in the Main method, and I need to access them from another method.

but I got the variables are not defined, though I defined them in the declerations/main.d.ts file as:

declare let voiceReady:any;
declare let x:any;

the main.ts file is;

/// <reference path="../declerations/main.d.ts" />
namespace CORE{
    export class Program {
      public static Main(): void {
            var voiceReady = new CORE.Listen(CORE.commands).commands;
            console.log(voiceReady);
            var x = 560;
            Program.execute('anything');
     }


        public static execute(spokenText:string):void{
            console.log('123');
            console.log(x);
            console.log(voiceReady);
       }
    }
}

UPDATE If I removed the deceleration from the .d.ts file, and added them to the class itself, I get compilation error as shown below:

Declare them as properties of the Program class.

namespace CORE{
export class Program {

    //Declare the properties here and access them in the methods
    static voiceReady: any;       

    public static Main(): void {
      this.voiceReady = new CORE.Listen(CORE.commands).commands;
      console.log(this.voiceReady);
      Program.execute('anything');
    }

    public static execute(spokenText:string):void{
        console.log(this.voiceReady);
     }
  }
}

If you want to reference from another class, import it outside your module like

import { Program } from "./Program";

and use it in your class like Program.Main();.

I got compilation error, I updated my question with this error, as I can not upload pic here, so I uploaded it in the question itself.
