A word-spotting experiment was conducted to investigate whether rhythmic consistency and phrase-final lengthening facilitate performance in Korean. Listeners had to spot disyllabic and trisyllabic words in nonsense strings organized in phrases with either the same or variable syllable count; phrase-final lengthening was absent, or occurring either in all phrases or only in the phrase immediately preceding the target. The results show that, for disyllabic targets, inconsistent syllable count and lengthening before the target led to fewer errors. For trisyllabic targets, accuracy was at ceiling, but final lengthening in all phrases reduced reaction times. The results imply that both rhythmic consistency (i.e., regular syllable count) and phrase-final lengthening play a role in word-spotting and, by extension, in speech processing in Korean, as in other languages. However, the results also reflect the language specific role of prosodic cues. First, the cues here were used primarily with disyllabic targets, which were cognitively more demanding to process partly due to their high phonological neighborhood density. Second, the facilitating effect of rhythmic consistency was weak, possibly because strict consistency is not present in spoken Korean. Overall, rhythmic consistency facilitated spotting when targets mapped onto phrases, confirming the importance of phrasal organization in Korean speech processing.
进行了一项单词识别实验，以研究节奏一致性和短语结尾延长是否有助于韩语的语言表现。听众必须在由音节数相同或不同的短语组成的无意义字符串中识别双音节和三音节单词；短语结尾延长不存在，或者在所有短语中出现，或者仅在目标前的短语中出现。结果表明，对于双音节目标，音节数不一致和目标前的延长会导致更少的错误。对于三音节目标，准确率达到上限，但所有短语中的结尾延长减少了反应时间。结果表明，节奏一致性（即规则的音节数）和短语结尾延长在单词识别中都起作用，进而在韩语的语音处理中也起作用，就像在其他语言中一样。然而，结果也反映了韵律线索的语言特定作用。首先，这里的线索主要用于双音节目标，双音节目标在认知上处理起来要求更高，部分原因是它们的语音邻域密度高。其次，节奏一致性的促进作用较弱，可能是因为韩语口语中不存在严格的一致性。总体而言，当目标映射到短语上时，节奏一致性有助于识别，这证实了短语组织在韩语语音处理中的重要性。
