Pronouncing -ы at the end of words really has me stumped. At forvo.com, at the end of of вопросы, it's pronounced like the computer voice - sort of like "-ay". or "eh".
But for столы, аt forvo.com, -ы sounds more like и ("ee"), and not at all like the computer voice "ay/eh".
And neither one sounds like the -ы in Мы or Вы
