The relation between word recognition and the estimate of the percentage of words understood was examined for monosyllabic words. Six-hundred and sixteen words were presented to 30 subjects in four signal-to-noise ratios (SNR) under five high pass, five low pass, and in the unfiltered condition. In each condition the subjects listened to 14 words with the carrier phrase ``you will write'' preceding each word. Subjects were instructed to write down each word, and at the end of each set of 14 words, to estimate the percentage of words that they understood in 7.5% increments. The subjects were not able to reliably estimate the words that they correctly understood based upon their identification of the words. Confusion matrices for 10 of the 30 subjects show the filter conditions and phonemic classifications that subjects consistently misjudged as having correctly understood.
