Vocaboly
A few weeks back I came to know about a vocabulary builder software program called Vocaboly. I went to the Voacboly Web Site and downloaded the trial version. The trial version is fully functional. The only limitation is that it uses computer voice. If you buy it, you will get high quality human voice of American accent.
Vocaboly is mainly for SAT, TOEFL, GRE, GMAT and general vocabulary. It contains more than 12,000 words and each word is provided with meaning, phonetic symbol and pronunciation. I liked the product. If you are a preparing for any of the above tests or want to improve your vocabulary, then download the trial version and give it a try.
