Text-to-speech

http://www.oddcast.com/home/demos/tts/tts_example.php 
  Text-to-speech is a very interesting website where you can type in the text, choose the language, the accent and even the different interesting effects, then you will hear the real people voice reading your text out. It offers 30 languages and more than 200 different people's voices for you to choose to read your text. 
  Language learners can learn different languages through this website. It will be very useful for English learners to distinguish the American English, British English and Australian English.  They can type in the same words and choose different voices to listen to the different pronunciations. For intermediate level students, they can use this website to help them to pronounce the new vocabulary if they don't have the access to any native-speakers in theri learnign settings. For entertaining, you can change the effect to listen to the interesting voice effects or you can type in words that you want to say to your friends and then record the voice to make it fun. 
  The only one problem with this website is that the length of the text is rather limited. It just can allow you to type in one to three short sentences one time. It may not be a good choice to read a passage for learners.
