Abstract : Various metrics are used to evaluate different aspects of speech communication. Most popular are measures of speech intelligibility. Other metrics that measure more than intelligibility are being employed, but they are not well known or readily available to potential users. This report contains reviews of some current practices and new research on metrics used to quantify speech communication. Three areas of speech communication are reported. The first reviews the development of speech intelligibility measures, the American National Standards Institute, S3.2-1989, 'Method for the Measurement of Intelligibility of Speech over Communication Systems,' and the proposed revision of the Articulation Index. The second addresses relationships between speech intelligibility and task performance showing that the complexity of both the speech an f the task affects performance. Some procedures allow determination of the amount bf intelligibility required to complete specific tasks. The third area addresses the roles of multiple modalities in speech perception, primarily the auditory and visual, in areas of integration models, generalizability theory, tests of basic discrimination abilities, and sequence comparison measurement techniques. Additional information of these topics is available from the individual researchers.
