To enable differences in modes of glottal vibration to be studied, glottal air volume velocity waveforms can be recovered from speech recordings by inverse filtering. Most previous published work in this area has made use of analog filters. Digital inverse filters offer many advantages, including the ability to change filter settings to match changing vocal tract filter functions. Although the theory and many of the methods necessary for digital inverse filtering have been described in the literature, a straightforward description of the entire process has been lacking. The digital inverse filtering process developed for linguistic research at the UCLA Phonetics Laboratory is described in detail in this paper, with the intention of facilitating such work at other institutions.
为了能够研究声门振动模式的差异，可以通过逆滤波从语音记录中恢复声门空气体积速度波形。该领域以前发表的大多数工作都使用了模拟滤波器。数字逆滤波器具有许多优点，包括能够更改滤波器设置以匹配不断变化的声道滤波器功能。尽管数字逆滤波所需的理论和许多方法已在文献中有所描述，但仍缺乏对整个过程的直接描述。本文详细介绍了加州大学洛杉矶分校语音实验室为语言研究开发的数字逆滤波过程，旨在促进其他机构开展此类工作。
