如果每个音素都由一个单位音来提示，人类就不能很好地感知语音。事实上，许多音素都经过编码，这样一个单一的声学提示就可以并行地携带有关连续音素片段的信息。这降低了必须感知离散声音的速度，但代价是线索和音素之间的复杂关系：线索随着上下文的不同而变化很大，在这些情况下，没有音素大小的可交换声学片段。因此，音素感知需要一个特殊的解码器。一种可能的模型假设，编码发生在关节肌肉的(不变)神经运动命令的水平之下。然后，解码器可以通过将输入的语音声音与这些命令相关联来识别音素。
Man could not perceive speech well if each phoneme were cued by a unit sound. In fact, many phonemes are encoded so that a single acoustic cue carries information in parallel about successive phonemic segments. This reduces the rate at which discrete sounds must be perceived, but at the price of a complex relation between cue and phoneme: cues vary greatly with context, and there are, in these cases, no commutable acoustic segments of phonemic size. Phoneme perception therefore requires a special decoder. A possible model supposes that the encoding occurs below the level of the (invariant) neuromotor commands to the articulatory muscles. The decoder may then identify phonemes by referring the incoming speech sounds to those commands.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
