PyDial

PyDial is an open-source end-to-end statistical spoken dialogue system toolkit which provides implementations of statistical approaches for all dialogue system modules. Moreover, it has been extended to provide multi-domain conversational functionality. It offers easy configuration, easy extensibility, and domain-independent implementations of the respective dialogue system modules.

PyDial is a scientific system developed for scientific purposes and actively used for research by the Dialogue Systems Group at the University of Cambridge. Although we put great effort into designing clean interfaces and easily understandable structures, some the code will not necessarily be up to commercial standards. As it is used actively by our reserach group, the code may also change in the future. However, the core intefaces have been designed in a way that there should not be any need to change them.
