Next time you need help pronouncing a word, why not try www.howjsay.com?
I learned about this site a while ago, but was recently reminded of it by LibrarianInBlack. It is quite useful and quite simple.
Just type a word into the search box. Howjsay.com returns an mp3 file with the correct pronunciation of the word. Hover over the word to repeat the audio, as often as you like. The site also displays a listing of words near alphabetically to your search term.
A must site. Use it with your favorite on-line dictionary.
