Paper: Demonstration of a POMDP Voice Dialer

ACL ID P08-4001
Title Demonstration of a POMDP Voice Dialer
Venue Annual Meeting of the Association of Computational Linguistics
Session Main Conference
Year 2008

This is a demonstration of a voice di- aler, implemented as a partially observable Markov decision process (POMDP). A real- time graphical display shows the POMDP’s probability distribution over different possi- ble dialog states, and shows how system out- put is generated and selected. The system demonstrated here includes several recent ad- vances, including an action selection mecha- nism which unifies a hand-crafted controller and reinforcement learning. The voice dialer itself is in use today in AT&T Labs and re- ceives daily calls.
