Miller-Nicely data on the auditory confusion of 16 consonant phonemes.
A symmetric matrix of the misclassification probabilities of 16 English consonant phonemes.
Miller and Nicely (1955) obtained the confusions by exposing female subjects to a series of syllables consisting of one of the 16 consonants followed by the vowel a under 17 different experimental conditions. The data provided are obtained from aggregating the six so-called flat-noise conditions in which only the speech-to-noise ratio was varied into a single matrix of misclassification frequencies.
The data set is also contained in file ‘mapclus.data’ in the shell archive http://www.netlib.org/mds/mapclus.shar.
