两个实验比较了合成单音节词表和自然单音节词表的回忆，以确定先前显示的由规则产生的合成语音的感知困难的位置[D]。李建军，李建军，李建军，等[j]。如果合成语音的感知在早期编码阶段需要增加处理能力，那么当短期记忆受到不同的压力时，合成语音和自然语音之间的回忆差异就会出现。在第一个实验中，使用三种呈现速度（每个单词1秒、2秒和5秒）来操纵对短期记忆的要求。尽管在所有呈现率下，合成列表的回忆能力都较差，但合成刺激的减少并没有随着呈现率的提高而增加。在第二个实验中获得了类似的结果模式，在每个口语单词列表之前，视觉上呈现不同长度的数字串（0、3和6位）以供记忆。然而，召回……
Two experiments comparing recall for synthetic and natural lists of monosyllabic words were conducted to determine the locus of previously demonstrated perceptual difficulties for synthetic speech produced by rule [D. B. Pisoni and S. Hunnicutt, ICASSP, 572–575 (1980)]. If the perception of synthetic speech demands increased processing capacity in early encoding stages, recall differences between synthetic and natural speech should arise when short‐term memory is differentially stressed. In the first experiment three presentation rates (1, 2, and 5 s per word) were used to manipulate the demands placed on short‐term memory. Although recall was consistently poorer for the synthetic lists at all presentation rates, the decrement for synthetic stimuli did not increase with faster rates. A similar pattern of results was obtained in the second experiment in which strings of digits of varying length (0, 3, and 6 digits) were presented visually for retention prior to each spoken word list. However, the recall of...
