通过同时多通道全带宽记录来研究高频能量的指向性，研究了水平平面上的语音和歌唱指向性。这种方法不仅可以利用长期平均频谱对运行语音进行准确分析，而且可以检查单个瞬变音素的指向性。几个声音产生因素可能影响指向性进行了检查。指向性在不同的生产方式（说话和唱歌）之间没有差异，在性别和生产水平（柔和、正常和响亮）之间只发现了轻微的差异，在更高的频率中更为明显。在特定的不发音摩擦音之间发现了很大的指向性差异，在4、8、16 kHz的频带中，/s、integral/比/f、theta/更具指向性。(C) 2012美国声学学会。[http://dx.doi.org/10.1121/1.4725963]
Speech and singing directivity in the horizontal plane was examined using simultaneous multi-channel full-bandwidth recordings to investigate directivity of high-frequency energy, in particular. This method allowed not only for accurate analysis of running speech using the long-term average spectrum, but also for examination of directivity of separate transient phonemes. Several vocal production factors that could affect directivity were examined. Directivity differences were not found between modes of production (speech vs singing) and only slight differences were found between genders and production levels (soft vs normal vs loud), more pronounced in the higher frequencies. Large directivity differences were found between specific voiceless fricatives, with /s,integral/ more directional than /f,theta/ in the 4, 8, 16 kHz octave bands.
