Abstract

The phonemic substitution errors of ten apractic speakers were analyzed to investigate the effects of markedness on speech production patterns. Results revealed that: more errors were produced on phonemes high in markedness; more changes in markedness were from marked to unmarked than unmarked to marked; and errors and directional changes in markedness were positively correlated with ease of articulation. The findings were interpreted as a systematic effort by the apractic speakers to reduce the complexity of articulatory gestures required to produce phonemes.

摘要

分析了10名失用症患者的音素替代错误，以研究标记性对言语产生模式的影响。结果显示：标记性高的音素产生的错误更多；标记性变化中从标记性到非标记性的比从非标记性到标记性的更多；标记性方面的错误和方向性变化与发音难易程度呈正相关。这些发现被解释为失用症患者为降低发出音素所需的发音动作复杂性而做出的系统性努力。
