英语辅音（16）是在频率失真和随机掩蔽噪声的语音通信系统中说出的。听众被迫猜测每一个声音，当一个声音与另一个声音混淆时，所有的错误都被计算在内。使用噪声或低通滤波，混淆落入一致的模式，但使用高通滤波，错误是随机分散的。对这16个辅音的发音分析提供了一个由5个发音特征或“维度”组成的系统，这些特征或“维度”用于表征和区分不同的音素：发声、鼻音、亲和力、持续时间和发音位置。数据表明，发声和鼻音几乎没有受到影响，而这个地方受到低通和嘈杂系统的严重影响。有迹象表明，对这5个特征中任何一个的感知相对独立于对其他特征的感知，因此就好像涉及5个独立的简单通道，而不是单个复杂通道。
English consonants (16) were spoken over voice communication systems with frequency distortion and with random masking noise. Listeners were forced to guess at every sound and a count was made of all the errors resulting when one sound was confused with another. With noise or low-pass filtering, the confusions fall into consistent patterns, but with high-pass filtering the errors are scattered quite randomly. An articulatory analysis of these 16 consonants provides a system of 5 articulatory features or "dimensions" that serve to characterize and distinguish the different phonemes: voicing, nasality, affrication, duration, and place of articulation. Data indicate that voicing and nasality are little affected and that place is severely affected by low-pass and noisy systems. Indications are that perception of any one of these 5 features is relatively independent of the perception of the others, so that it is as if 5 separate, simple channels were involved rather than a single complex channel.
