I came across a very useful online service the other day called Tip of my Tongue that helps you to recollect words that you vaguely remember but just can't blurt out. I tried it out immediately on a word that I never seem to get right the first time - a word that means "pulverization" starting with "com" and ending with "tion." I entered the relevant information and here is the result:
Yes, I am always unsure of whether the 'u' or the 'i' comes first in "comminution." This site will be on the top of my list of bookmarks.
The other one reads out your text and the computer-generated voices are not too bad. The site at Read the Words even produces an mp3 recording of the text you paste in its window and sends it to you by e-mail. You can try out a demo by pasting text less than 100 characters in a window, selecting a voice and listening to it. If you like it, you could register and then paste larger chunks of text and have it read it out to you while you translate. You can register for a free account, and upload Word, PDF or HTML files and have the text read out to you (don't upload confidential documents!)
Try the 100-character demo first selecting different voices and see if you like what you hear before you register for a free account.
Have a great weekend!
