Speech clarity/intelligibility: test-retest reliability of magnitude-estimation scaling.
The reliability of magnitude-estimation scaling as a measure of overall clarity of speech was investigated. 40 subjects (M age = 19 yr.) provided magnitude-estimation responses for nine audiotaped versions of a nonsense sentence varying systematically in number of correct consonant phonemes. There was no significant difference in the magnitude-estimation responses of the subjects during two test sessions separated by one week. Analysis suggested that magnitude-estimation scaling is a reliable measure of speech clarity/intelligibility. This finding is discussed in relation to speech samples varying in aspects other than number of consonant phonemes correct and possible further clinical research applications.
