本文讨论了日语中两个著名的语音现象：元音清化和元音定时节奏。把元音清化看作是元音辅音化的过程，可能会改变日语的音节结构，导致偏离音节时节奏。为了研究与其他语言相比的自发日语，对OGI_TS的标签数据进行了分析。首先，在自发的日语中，元音清化似乎比在控制的语言中更频繁地发生。在自然言语中，即使在非典型的元音清化环境中，元音清化也经常发生。其次，节奏分析表明，它是接近音节定时节奏。这些结果表明，元音清化引起的自发日语偏离mora-timed节奏移动到音节定时。
This paper discusses two well-known phonetic-phonological phenomena of Japanese, vowel devoicing and mora-timed rhythm. Regarding vowel devoicing as a process of vowels getting consonantal, it may change the mora-templated syllable structures of Japanese, resulting in the deviation from mora-timed rhythm. To investigate spontaneous Japanese with comparison to other languages, the label data of OGI_TS was analyzed. First, it seemed that vowel devoicing occurs more frequently in spontaneous Japanese than in controlled speech. In spontaneous speech, vowel devoicing frequently occurs even in the environments non-typical of vowel devoicing. Next, rhythm analysis showed that it is close to syllable-timed rhythm. These results suggest that vowel devoicing caused spontaneous Japanese deviates from mora-timed rhythm moving to syllable-timed.
