音节清晰度与音位清晰度之间的统计关系

在大量普通话清晰度试验的基础上,根据汉语音节结构的具体分析,认为语言的内部信息——结构规律在言语的主观识别过程中是十分重要的因素。这特别表现在言语信号受到较大的干扰或失真,言语信号的物理特性已不能提供充分的识别条件时,内部信息发生较大的作用。本文提出了考虑到这一内部信息作用的音节清晰度与音位清晰度之间的统计关系。这一关系,比Fletcher与Steinberg所建立的统计关系,更好地符合大量试验的结果。

ON THE STATISTICAL RELATION BETWEEN THE SYLLABLE ARTICULATION AND THE PHONEME ARTICULATION

The internal information, i.e. the syllable formation rule, of the language plays an important role in the statistical relation between the syllable articulation and the phoneme articulation, especially when the articulation scores are low. This is taken account in deriving an expression for the relation between the syllable articulation and the phoneme articulation scores, which agrees well with the experimental results of standard colloquial Chinese and accounts for the differences between theory and experiment for English and Japanese by previous authors.
