基频（F0）变化是听力正常的听众用来指导退化语音的词汇分割的许多声学线索之一。本研究旨在探讨是否F0轮廓有利于安装人工耳蜗（CI）的听者的词汇分割。词汇边界错误模式下引起的不变和平坦的F0条件进行了比较，在三组：听众与传统的CI，听众与CI和保存低频声学听力，和正常听力的听众进行CI模拟。结果表明，所有的组参加音节的压力线索，以指导词汇分割，和F0轮廓促进性能的听众与低频听力。(C)2009年美国声学学会
Fundamental frequency (F0) variation is one of a number of acoustic cues normal hearing listeners use for guiding lexical segmentation of degraded speech. This study examined whether F0 contour facilitates lexical segmentation by listeners fitted with cochlear implants (CIs). Lexical boundary error patterns elicited under unaltered and flattened F0 conditions were compared across three groups: listeners with conventional CI, listeners with CI and preserved low-frequency acoustic hearing, and normal hearing listeners subjected to CI simulations. Results indicate that all groups attended to syllabic stress cues to guide lexical segmentation, and that F0 contours facilitated performance for listeners with low-frequency hearing.
