本研究测试听者是否使用F0，持续时间，或两者的某种组合来识别短话语中重音单词的存在。当参与者听着移动显示器上的物体的指令时，研究人员监测了参与者对之前提到的和新物体的眼球运动。关键试验中目标对象的名称从自然产生的话语中重新合成，使其具有高或低的F0和长或短的持续时间。当F0急剧上升时，对新物体的注视达到最高。当F0急剧下降时，对前面提到的物体的注视是最高的。这些结果表明，听者使用F0斜率来判断是否存在口音，而F0和持续时间本身并不是唯一决定口音解释的因素。
The present study tests whether listeners use F0, duration, or some combination of the two to identify the presence of an accented word in a short discourse. Participants’ eye movements to previously mentioned and new objects were monitored as participants listened to instructions to move objects in a display. The name of the target object on critical trials was resynthesized from naturally-produced utterances so that it had either high or low F0 and either long or short duration. Fixations to the new object were highest when there was a steep rise in F0. Fixations to the previously mentioned object were highest when there was a steep drop in F0. These results suggest that listeners use F0 slope to make decisions about the presence of an accent, and that F0 and duration by themselves do not solely determine accent interpretation.
