This study investigated the perception of lexical pitch accent contrasts between innovative and conservative listeners under a sound change. Younger and older listeners speaking Kyungsang Korean participated in the 2AFC identification task. The participants responded to stimuli systematically varying spectral and temporal F0 properties (i.e., peak duration, onset/peak F0 values) and talker voices (i.e., older vs younger talker). Results showed that younger listeners utilized the temporal cue differently from older listeners, and listeners' perception also varied by talker age. Discussion was made in terms of consistency between the perception and production and the effect of social information in speech perception.
本研究调查了在语音变化下创新型和保守型听者对词汇重音对比的感知。说庆尚韩语的年轻和年长的听者参与了 2AFC 识别任务。参与者对刺激做出系统的反应，刺激的频谱和时域 F0 属性（即峰值持续时间、起始/峰值 F0 值）和说话者的声音（即年长和年轻的说话者）发生变化。结果表明，年轻的听者与年长的听者在使用时域线索方面存在差异，而且听者的感知也因说话者年龄的不同而有所不同。讨论涉及到感知和产生之间的一致性以及言语感知中社会信息的影响。
