在3D听觉显示器中，声音通过耳机以一种方式呈现，使得它们似乎源自听众周围空间中的虚拟源。本文介绍了一种研究的可能优点，这样的显示带限语音的可懂度和说话人识别的背景下竞争的声音。不同的条件进行了调查：语音材料（单词/句子），演示模式（单声道/双耳/3D），竞争的谈话者（1-4），和虚拟的谈话者的位置（在45度的步骤周围的前水平面）的数量。12个听众的平均结果显示，与传统的双耳呈现相比，两个或更多个竞争的谈话者的3D呈现的语音可懂度增加。在存在两个或三个竞争的说话者的情况下，识别说话者的能力稍好，并且识别所需的时间显著更短。虽然说话者的绝对定位是相当差的，空间分离似乎有显着的影响，沟通。无论是语音可懂度，说话人识别，或本地化，没有发现之间的差异使用个性化的3D听觉显示和一般显示。(C)2000年美国声学学会。【S0001-4966（00）01104-3】。
In a 3D auditory display, sounds are presented over headphones in a way that they seem to originate from virtual sources in a space around the listener. This paper describes a study on the possible merits of such a display for bandlimited speech with respect to intelligibility and talker recognition against a background of competing voices. Different conditions were investigated: speech material (words/sentences), presentation mode (monaural/binaural/3D), number of competing talkers (1-4), and virtual position of the talkers (in 45 degrees-steps around the front horizontal plane). Average results for 12 listeners show an increase of speech intelligibility for 3D presentation for two or more competing talkers compared to conventional binaural presentation. The ability to recognize a talker is slightly better and the time required for recognition is significantly shorter fur 3D presentation in the presence of two or three competing talkers. Although absolute localization of a talker is rather poor, spatial separation appears to have a significant effect on communication. For either speech intelligibility, talker recognition, or localization, no difference is found between the use of an individualized 3D auditory display and a general display.
