From rule-based to statistical grammars: Continuous improvement of large-scale spoken dialog systems
14 years 20 days ago
Statistical Spoken LanguageUnderstandinggrammars (SSLUs) are often used only at the top recognition contexts of modern large-scale spoken dialog systems. We propose to use SSLUs a...
