The robot I work with (http://wiki.ros.org/Robots/AMIGO http://wiki.ros.org/Robots/AMIGO) uses a proprietary stand-alone package from Philips which works really well. Somehow, our license expired and now we use Festival, which works, but I really miss its old voice. Especially for Dutch text-to-speech it works quite well. But for the life of me I can't find a link of where you could buy it. Doing TTS correctly, with intonation etc. is really hard. Its not really my field, but I can imagine that getting intonation right is near impossible with just unannotated text.
