We describe HARC, a system for speech understanding that integrates speech recognition techniques with natural language processing. The integrated system uses statistical pattern recognition to build a lattice of potential words in the input speech. This word lattice is passed to a unification parser to derive all possible associated syntactic structures for these words. The resulting parse structures are passed to a multi-level semantics component for interpretation. 6 19a. NAME OF RESPONSIBLE PERSON

“…We have also used the Learner to acquire a set of vocabulary items and word classes for a class grammar (Derr and Schwartz, 1989) for use in HARC, the BBN Spoken Language System (Boisen, et al, 1989a), which incorporates the ACFG system as its natural language component. Though the Learner does not directly produce a class grammar, we used the syntactic categories, semantic classes, and inflectional paradigms and forms which it provides to produce a class grammar.…”

“…This paper discusses the unification-based grammar component of the BBN Delphi system, the natural language component of the BBN Spoken Language System. This grammar, previously discussed in [4] [5], is written in a variant of the Definite Clause Grammar formalism [17] and simultaneously assigns both syntactic structure and semantic interpretation to an utterance. The grammar comprises some 1300 rules (including those for terminal items), and has recently been evaluated on the ATIS air travel information domain with favorable results [2].…”

This paper presents recent natural language work on HARC, the BBN Spoken Language System. The HARC system incorporates the Byblos system [6] as its speech recognition component and the natural language system Delphi, which consists of a bottom-up parser paired with an integrated syntax/semantics unification grammar, a discourse module, and a database question-answering backend. The paper focuses on the syntactic and semantic analyses made in the grammar.
