关系声学不变性理论[Pickett，E. R.，等（1999）中所述。Phonetica 56，135-157]在不同速率的双音节口语中测试了日语塞音数量的区别。问题是，是否感知的单一和成对停止两个音素类别之间的边界是不变的速率，以及是否有一个密切的对应关系之间的感知和生产的边界。塞音闭合与词（其中“词”被定义为双音节）的持续时间比以前被认为是一个不变的参数，分类的两个类别的生产，但本研究发现，这一比例随不同的说话速度的看法。然而，知觉和生产数据的回归和判别分析表明，治疗停止关闭作为一个功能的词的持续时间与截距项代表的知觉和生产的界限非常好。这一结果表明，调整停止关闭的持续时间比（即，封闭与添加常数）的字是不变的，并区分两个音位类别清楚。总之，结果支持相关声学不变性理论，并帮助完善理论方面的确切形式“不变性”可以采取。(C)2010年美国声学学会。[DOI 10.1121/1.3458847]
The theory of relational acoustic invariance [Pickett, E. R., et al. (1999). Phonetica 56, 135-157] was tested with the Japanese stop quantity distinction in disyllables spoken at various rates. The questions were whether the perceptual boundary between the two phonemic categories of single and geminate stops is invariant across rates, and whether there is a close correspondence between the perception and production boundaries. The durational ratio of stop closure to word (where the "word" was defined as disyllables) was previously found to be an invariant parameter that classified the two categories in production, but the present study found that this ratio varied with different speaking rates in perception. However, regression and discriminant analyses of perception and production data showed that treating stop closure as a function of word duration with an intercept term represented the perception and production boundaries very well. This result indicated that the durational ratio of adjusted stop closure (i.e., closure with an added constant) to the word was invariant and distinguished the two phonemic categories clearly. Taken together, the results support the relational acoustic invariance theory, and help refine the theory with regard to exactly what form 'invariance' can take.
