Little is known about the effects of listener characteristics or listening conditions on intelligibility scores. This study compared intelligibility scores of dysarthric speech achieved under a standard listening condition with those obtained in non-standard conditions and investigated the effect of listener age, gender and familiarity with speaker accent on intelligibility scores. No differences were observed in the mean intelligibility scores across standard and non-standard listening conditions. However, mean range of scores in the standard condition was lower than in the non-standard condition (t = 3.07, df 90, p<.003; 95% CI 2.04-9.76). No main effects of listener age, gender or familiarity of accent were observed. When composite effects were examined increased age in male listeners was associated with reduced intelligibility scores. Results from the current study suggest that when conducting intelligibility research listening conditions should be standardised and that adult listeners of either gender and any age may be used to test intelligibility outcomes providing hearing acuity is taken into consideration.
关于听众特征或聆听条件对可懂度得分的影响，目前所知甚少。本研究比较了在标准聆听条件下获得的构音障碍语音可懂度得分与在非标准条件下获得的得分，并调查了听众年龄、性别以及对说话者口音的熟悉程度对可懂度得分的影响。在标准和非标准聆听条件下，平均可懂度得分未观察到差异。然而，标准条件下得分的平均范围低于非标准条件（t = 3.07，自由度90，p<.003；95%置信区间2.04 - 9.76）。未观察到听众年龄、性别或对口音熟悉程度的主效应。当检查综合效应时，男性听众年龄的增加与可懂度得分降低有关。当前研究的结果表明，在进行可懂度研究时，聆听条件应标准化，并且在考虑听力敏锐度的情况下，任何年龄的成年听众，无论男女，均可用于测试可懂度结果。
