This paper presents a method for extracting both syntactic and semantic tags. An extended CFG parser works in conjunction with an HMM model, which handles unknown words and partially known words, to yield a complete syntactic and semantic interpretation of the utterance. Four experiments and applications were performed using the paradigm to show the usefulness of the approach in processing spoken sentences.
