Effects of listeners' experience on two measures of intelligibility

10 speech-language pathologists with extensive experience in judging speakers' intelligibility and 10 control subjects with no such previous experience provided written identification and magnitude-estimation scaling judgments of the intelligibility of nine audiotaped speech samples. Analysis indicated no significant main effect for experience on either the written identification or the magnitude-estimation scaling tasks. Implications for the continued use of magnitude-estimation scaling as a measure of speech intelligibility are discussed.
