This is an interactive demo of CSTR's "Festival" speech synthesiser, which is software capable of making artificial speech in place of a real human. Festival is the most complete freeware multilingual, general-purpose synthesis system available. It is used by numerous research sites and other projects around the world. Further information is available on the Festival project page.

Unlike the simpler demo here, the demo on this page gives access to many more voices which have been developed for Festival.

Broadly, three synthesis methods are available in this demo:
