Analysis-by-synthesis

综合分析说

A theory of speech perception which credits listeners with an internal, language-specific mechanism that responds to incoming speech by selecting certain acoustic cues, and then attempting to synthesize a replica of the input. When this is achieved, the synthesis has, in effect, carried out an analysis of the input. Such a procedure, it is argued, has the merit of being able to explain how listeners resolve the acoustic variability in signals, stemming from the differences between speakers, contexts, etc.

一种言语感知理论，主张听话人有一个内在的、针对特定语言的机制，它对输入言语的反应是先选择某些声学提示特征，然后尝试综合成一个输入的复制品。达到这一步，综合过程实际已完成对输入的分析。这一理论认为，这样一个程序的优点是能够解释听话人如何分辨由说话人或语境等因素的差异而造成的信号在声学上的变异。
