Abstract

We describe completed and ongoing research on HALEF, a telephony-based open-source spoken dialog system that can be used with different plug-and-play back-end modules. We present two examples of such a module, one which classifies whether the person calling into the system is intoxicated or not and the other a question answering application. The system is compliant with World Wide Web Consortium and related industry standards while maintaining an open codebase to encourage progressive development and a common standard testbed for spoken dialog system development and benchmarking. The system can be deployed towards a versatile range of potential applications, including intelligent tutoring, language learning and assessment.

Popular grammar formats include JSGF (Java Speech Grammar Format), SRGS (speech recognition grammar specification) and ARPA (Advanced Research Projects Agency) formats.

Since the data collected during different ALC experiments are not balanced in terms of class and gender, we removed all speakers that were recorded in only one of the classification states. We then discarded as many male speakers (selected at random) as necessary to achieve gender balance.
