Few days back I had posted about Windows Live Messenger Translation Bot which translates our IM conversation into various languages.
Now this MTBot can not only translates but speaks also, whatever it translates. To begin with, it now speaks English and Spanish. So whatever it translates into Spanish can also be heard. Great work by MTBot prototype project.
So to try this first invite the bot by saying hello. (For those who have not added this bot to their contact list, please check Windows Live Messenger Translation Bot ). After saying hello, it will respond and you select "es" for Spanish. Then bot*say Do you Speak Spanish ?
You can also use bot:say but it gets turned into emoticon but it also works.So use bot*say <followed by sentence you want to translate and hear>.
