众所周知,注视方向可以影响听觉空间知觉,但这种交互作用对复杂听力任务中的表现的影响尚不清楚。在本研究中,我们调查了在“鸡尾酒会”听力情景中,凝视方向对言语清晰度是否有可测量的影响。我们展示了位于0°、  ±  15°和 ± 30°方位的五个扬声器的数字序列,并要求参与者重复指定目标扬声器提供的数字。在不同的试验阶段中,参与者在视觉上专注于目标位置或非目标位置呈现的线索。持续追踪眼位以监测依从性。当固定在靶上(与非靶标相比)时,性能最好,这种效果的大小取决于特定的配置。这一结果表明,即使在没有视觉语音信息的情况下,凝视方向也会对多个说话者的混合语音产生影响。
It is well established that gaze direction can influence auditory spatial perception, but the implications of this interaction for performance in complex listening tasks is unclear. In the current study, we investigated whether there is a measurable effect of gaze direction on speech intelligibility in a “cocktail party” listening situation. We presented sequences of digits from five loudspeakers positioned at 0°,  ±  15°, and ± 30° azimuth, and asked participants to repeat back the digits presented from a designated target loudspeaker. In different blocks of trials, the participant visually fixated on a cue presented at the target location or at a nontarget location. Eye position was tracked continuously to monitor compliance. Performance was best when fixation was on-target (vs. off-target) and the size of this effect depended on the specific configuration. This result demonstrates an influence of gaze direction in multitalker mixtures, even in the absence of visual speech information.
