Q. How can I learn the correct English pronunciation of words?

Google Translate has a pronunciation feature.  When you translate a word, you can click on the icon that looks like a small speaker (when you mouse-over the icon, it will read "Listen").  The direct link to Google Translate is http://translate.google.com/?hl=en
