Am I joking?.....No I'm not......Its very easy.
1) Quickly open your notepad.
2) Copy the content in Blue
Dim msg, sapi
msg=InputBox("Enter your text","Message Box")
3) Paste it in Notepad
4) Save it with any name but the extension should be ".vbs"
5) If you wish to name it "XYZ"...then the file name will be "XYZ.vbs"
6) Close the window.
Now open the file, type anything in it and press enter..... Bingo!!!....You should be able to hear what you just typed.
But make sure your speakers are turned on ;)
