Abstract

Statistical Spoken Language Understanding grammars (SSLUs) are often used only at the top recognition contexts of modern large-scale spoken dialog systems. We propose to use SSLUs at every recognition context in a dialog system, effectively replacing conventional, manually written grammars. Further- more, we present a methodology of continuous improvement in which data are collected at every recognition context over an entire dialog system. These data are then used to auto- matically generate updated context-specific SSLUs at regular intervals and, in so doing, continually improve system per- formance over time. We have found that SSLUs significantly and consistently outperform even the most carefully designed rule-based grammars in a wide range of contexts in a cor- pus of over two million utterances collected for a complex call-routing and troubleshooting dialog system.
