Frazier (1975) 提出了一种自适应梳状滤波技术，用于增强因添加竞争语音信号而降低的语音信号的清晰度。本文报告了对所提出的系统处理的材料的语音清晰度的一系列初步测试。男性和女性所说的句子既被用作目标，也被用作干扰器。对系统参数、扬声器和目标与干扰器幅度比的各种组合进行了测试。在没有干扰的情况下对已处理的材料进行基线测试，并在不同的目标与干扰器比率下对未处理的材料进行基线测试。
Frazier (1975) proposed an adaptive comb-filtering technique for enhancing the intelligibility of speech signals degraded by the addition of competing speech signals. This paper reports on a series of preliminary tests of speech intelligibility for materials processed by the proposed system. Sentences spoken by males and females were used as both targets and jammers. Tests were conducted for various combinations of system parameters, speakers and target-to-jammer amplitude ratios. Baseline tests were conducted for processed materials in the absence of interference and for unprocessed materials at various target-to-jammer ratios.
