A N N O U N C I N G the Carnegie Mellon Open Source Communicator Spoken Dialog Toolkit We are pleased to announce the initial release of the Open Source Communicator Spoken Dialog Toolkit (CSDTk). The Toolkit contains all necessary components for building and deploying advanced spoken language dialog systems, for both desktop and telephony applications. The system is freely available for download at http://www.speech.cs.cmu.edu/Communicator/ You can try out the telephone-based Travel Planning system at +1 877 CMU-PLAN (268-7526). The Carnegie Mellon Communicator Toolkit is based on the CMU Communicator, a top-performing advanced dialog system developed as part of the DARPA Communicator program. It is distributed with a working implementation for a Travel Planning domain. CSDTk is built on top of the open source Galaxy Communicator Software Infrastructure. As distributed, the CSDTk operates in desktop mode. With the addition of suitable hardware it can be connected to, and used over, the telephone system. The CSDTk incorporates the following major components: - Sphinx II decoder(*), with automatic endpointing and barge-in management. Sphinx is a speaker-independent, large-vocabulary recognizer. The distribution includes acoustic, lexical and language models for the Travel Planning domain. - Phoenix semantic parser(*). With Travel Planning semantic grammar. - Helios post-parser, including understanding confidence management. - AGENDA Dialog Engine, including handler objects for Travel Planning. - DateTime understanding module - Travel back-end, including live access to airline and hotel information for about 500 destinations world-wide. - Rosetta language generation module, including the CMU Stochastic Generation Engine. - Festival(*) text-to-speech synthesizer, with Travel Planning voice database. The systems in modules marked (*) are already available as separate distributions. However, the Toolkit distribution includes versions with interfaces specifically designed for the Toolkit. Note that in addition to the CSDTk software you will need to install Perl and a database server, such as MySQL. The initial distribution is for Windows.
