I tried the first method which gave me the option to turn the voice off but even though there was a check mark for "off" that annoying woman's voice continued to speak. I could not find an active "option" button to push and was not able to use that second method.
Thanks a bunch for the guidance. I tried successfully the second method (i.e. hitting the Options button four time while in the "Roku Home " page) and got rid of that annoying voice). Some how Roku should have that message prominently displayed.
