Figures

FIG. 1.

Mean word intelligibility rates (in percent) for 44 talkers for N and NN listeners in sessions 1 and 2 for the word and triplet conditions. Error bars represent ±1 standard error.

FIG. 2.

Word intelligibility rates for individual talkers (w: woman, m: man, c: child) pooled across word and triplet conditions, for N and NN listeners.

FIG. 3.

Word intelligibility rates (%) for N and NN listeners for the 40 words with the lowest intelligibility for N listeners pooled across word and triplet conditions (not all labels are shown).

TABLE I.

Word intelligibility scores for NN listeners (in percent correct) for three talker groups (women, men, children; for each cell in each group N = 30 listeners). Standard deviation measures are given in italics.

TABLE II.

Word intelligibility scores for NN listeners (in percent correct) for first and second halves of test runs within each experimental condition (for each cell N = 30). Standard deviation measures are given in italics.

TABLE III.

Correlation coefficients (Pearson’s r) showing significant relations between the number of unknown words and intelligibility measures (in rau). T-W = Difference between mean scores for triplets—words in session 1. p < 0.05*; p < 0.01**; n.s. = non-significant. N = 30.
