Text to Speech in the browser?

I've seen it done (google does it with google translate) but are there any op开发者_Python百科en source libs?

Thanks all!

I could be wrong, but I doubt they're doing this in JavaScript in truth. They obfuscate their code pretty well, but I bet that what they do is have a sound file served up after doing the text-to-speech on the server, just using JS to load the src url of the audio object.

Doing it on the server yields a bunch more options: http://www.google.com/search?aq=f&sourceid=chrome&ie=UTF-8&q=open+source+text+to+speech

You must check this out http://thetutlage.com/post=TUT178 , it is 100% browser based using javascript and seems promising to me..
