Text to speech on Quizlet.com [closed]

How did they implement text to speech (TTS)? Is there an open, free API for TTS synthesis? I know about Google Translate, but the license is not clear to me (another issue is that they block a request if it contains a referrer). Any idea?

Majdron,

I'm a lead developer at Quizlet. We're using a combination of our own technology and licensing/purchasing TTS software from several different companies.

There are some open source TTS engines/voices:

  • http://www.cstr.ed.ac.uk/projects/festival/
  • http://www.babelfish.org/tts-free.htm
  • http://espeak.sourceforge.net/
  • http://freetts.sourceforge.net/docs/index.php
  • http://mary.dfki.de/

Good luck!

The voices sound exactly the same as http://www.neospeech.com. Also, their list of languages match exactly.

It's not free, you have to license it.
