abstract: Our objective was to build a speech interface for use with a medicaldecision-support application. We used a commercially available speech-recognitionsystem to obtain textual representations of input utterances and we generatedgrammars to supply the anticipated utterances for the recognition system. Wedesigned the interface to identify controlledvocabulary terms from grammatical and ungrammatical textual transcriptions ofutterances. Our method included two steps: translation of the controlledvocabulary terms and textual representations of input utterances into keyword-based canonical forms, and matching canonical forms of input utterances tocanonical forms of the controlled vocabulary terms. Evaluation of the speechinterface indicated that this matching approach increased the identificationof terms from misrecognized utterances.
