本研究旨在探讨日语单音节与双音节塞音长度对比的声学相关性。研究的建议是，多个声学特征协变与停止长度的区别，这些功能可在信号中作为潜在的次要线索。结果支持这一建议，揭示了存在的几个声学特征协变的单与双生的对比度在持续时间和非持续时间域。具体来说，前元音较长，后元音较短，前元音到后元音的基频和强度变化较大，并且有证据表明，双辅音的音质比单辅音的音质更脆。研究还表明，元音音长、基频和强度的变化具有较强的范畴化能力。
This study explores acoustic correlates to the singleton vs. geminate stop length contrast in Japanese. The proposal examined is that multiple acoustic features covary with the stop length distinction and that these features are available in the signal as potential secondary cues. The results support the proposal, revealing the presence of several acoustic features covarying with the singleton vs. geminate contrast in both durational and non-durational domains. Specifically, the preceding vowel is longer, the following vowel is shorter, there arc greater fundamental frequency and intensity changes from the preceding to the following vowel, and there is evidence of more creakiness in voice quality for geminate than singleton consonants. It is also demonstrated that the vowel durations, as well as fundamental frequency and intensity changes have fairly strong categorization power.
