Improving on existing TTS technology, Loquendo (a Nuance company) is showing the world that "even computers can show their feelings," with a huge array of TTS engines that are not only more advanced, but significantly more dynamic than existing alternatives.

The bad news is that only two of these engines are currently available for Android – Italian TTS Paola and American English TTS Susan. That being said, we can still hope that more of Loquendo's engines will be adapted for Android, and, in the meantime, Loquendo's website has amazing demos of all its TTS voices, both static and interactive.
