This paper presents an environment for collecting clinical data using structured speech input.The system uses nomenclature terms and data consistency rules to limit speech input to a discrete set of phrases which can be configured to support a wide range of studies.This information is stored in an event-oriented data odel as strongly typed observations for subsequent distribution and data analysis.The use of speech input should result in increased efficiency during hands-busy data collection tasks.The strongly type data,as opposed to free- form narratives,will ensure a quantitative base of information for analysis and clinical decision support.
