Speaking involves both retrieving the sounds of a word (phonological planning) and realizing these selected sounds in fluid speech (articulation). Recent phonetic research on speech errors has argued that multiple candidate sounds in phonological planning can influence articulation because the pronunciation of mis-selected error sounds is slightly skewed towards unselected target sounds. Yet research to date has only examined these phonetic distortions in experimentally-elicited errors, leaving doubt as to whether they reflect tendencies in spontaneous speech. Here, we analyzed the pronunciation of speech errors of English-speaking adults in natural conversations relative to matched correct words by the same speakers, and found the conjectured phonetic distortions. Comparison of these data with a larger set of experimentally-elicited errors failed to reveal significant differences between the two types of errors. These findings provide ecologically-valid data supporting models that allow for information about multiple planning representations to simultaneously influence speech articulation.
说话涉及到检索单词的发音(语音规划)以及在流畅的言语中实现这些选定的发音(发音)。最近对言语错误的语音研究认为,语音规划中多个候选发音会影响发音,因为错误发音的选择略微偏向于未选择的目标发音。然而,迄今为止的研究仅在实验诱发的错误中检查了这些语音扭曲,这使得人们怀疑它们是否反映了自发言语中的倾向。在这里,我们分析了英语母语者在自然对话中与同一说话者所说的匹配正确单词的言语错误的发音,发现了推测中的语音扭曲。将这些数据与更大的一组实验诱发的错误进行比较,并未发现两种类型的错误之间存在显著差异。这些发现提供了具有生态效度的支持模型的数据,这些模型允许关于多个规划表示的信息同时影响言语发音。
